Brief Summary: Today, sea level rise due to increasing global average temperatures is a huge threat to low-lying, coastal, and island communities. Sea level is rising, in part, from ice that is melting on Antarctica and Greenland. To understand how much sea level may rise in the near future, scientists look to the geologic past, when global temperatures were much warmer than today or close to the temperatures predicted for the coming decades. In this study, scientists looked at how much ice was lost from the Wilkes Subglacial Basin of East Antarctica during a time when global average temperatures were about 2 degrees Celsius warmer than pre-industrial values. They find that during these warmer periods, called interglacials, there was significant ice that melted from East Antarctica, and contributed to sea level rises. Thus, in the future, the ice melting from East Antarctica will contribute more to sea level rise than we previously thought.

Data used and Methods: Sediment from a deep-sea core drilled from the continental margin of East Antarctica was used in this study (Figure 1). From this sediment core, the authors analyzed the different types of sediment contained within the core through time. From the changes in sediments, the scientists could tell how much erosion was occurring. They also looked at the neodymium (Nd) isotopes from the sediments. Nd isotopes are a good way to also trace where the sediments in the core were coming from, so the scientists could determine not only how much erosion was taking place within East Antarctica, but where the eroded sediment was coming from. Increased erosion and a shift in the Nd isotope records indicate increased glacial melt and ice retreat on East Antarctica, thus the authors could tell through geologic time when and approximately how much the ice melted.

Results: Over the past 800,000 years, Earth’s climate has oscillated between cooler (glacial) and warmer (interglacial) periods (read more about this on our CO2 page). During some interglacial periods (times when the climate was warmer), the scientists found that the East Antarctic Ice Sheet began to erode the rock on which it sits and melted significantly. This led to increased sea levels within a world that was less warm than today.

Why is this study important? This study places new approximations on how much melting from East Antarctica could occur in a warming world, and how much that could raise sea level. Climate scientists think that if all the ice on East Antarctica were to melt, it would lead to approximately 53 meters of sea level rise globally! With the data from this study, it will provide new constraints on melting ice in a warming world, which will be incorporated into climate models of the future climate. This data will be given to policymakers to help us best prepare and mitigate the consequences of climate change.

Hobbies are important!

Sarah, Jen, and Adriane here-

Ever wondered what a scientist does for fun? Many people are surprised to find out that people who do science are into just about every single hobby that can be done! I think shows like the Big Bang Theory, that paint scientists as really nerdy and incapable of doing non-science related things, can make people think that scientists are really like that in real life (some of us are! Definitely nothing wrong with that- but scientists are a pretty diverse group of people). Why are hobbies important, though? Well, hobbies keep me sane. They give me a chance to take a break, completely, from work and do something challenging and fun. They give me a chance to make new friends outside of science and give me things to look forward to, when work gets tough.

So what kind of hobbies are scientists into? Well, we here at Time Scavengers wrote a group post so you could see the the types of stuff we get up to in our spare time.

Sarah

The three trilobites I’ve cross stitched so far! (This is my very first attempt at any form of embroidery-I’m pretty proud of them!

My favorite thing to do is read! I have a challenge with myself–I read at least 50 books a year. I don’t have a favorite genre, really. I’ll read just about anything: fiction, classics, memoirs, young adult–I just like reading stories of other people’s lives, whether they’re real or fictional. I read every night before I go to sleep and I always have an audiobook that I listen to while I’m vacuuming, walking to class, or driving in the car. Right now, as this post is being written, I’m rereading Kate Chopin’s The Awakening and listening to Tara Westover’s Educated (both super good–highly recommend!). I’ve read books for fun for as long as I can remember. Little known fact about me- I was on a competitive reading team in middle school aka I was super cool and not at all nerdy.

I’m also really into crafts. My mom is an art teacher, so she taught me how to do a lot of different crafty things (even if I inherited none of her skill). I love to paint, decoupage, and create all kinds of things. Recently, I decided to take up learning how to embroider. So far, I’ve cross stitched a few different trilobites to hang up in my office! Around my house are the relics of old craft projects that I’ve made and am probably way too proud of.

Another project of mine that I’ve taken up is learning American Sign Language. I’ve always wanted to learn and I recently decided that there was no time like the present. So, for the past year, I’ve been taking online classes through my local community college and spending time on weekends with the Tampa Deaf community to learn how to communicate via sign. It’s been a total blast and I’m hoping to keep learning!

Jen

Jen at Graham Swamp Conservation Area where she was biking and checking out dredged sediment from the beach. Fossils galore!!

My favorite thing to do is be outside. After working for any amount of time the only thing that really refreshes me is getting some sunlight and air. Most of my work involves sitting at my computer so I constantly get burned out from staring at my screen. These days I do a lot of biking both on long greenways on my road bike and on trails on my mountain bike. Jeb even made some nice trails on our property in Gainesville – almost two miles! I used to do a lot of trail running when we lived in Knoxville but would have to take long breaks to offset my shin splints, which would get really painful at times. I also like to examine the wildlife – what’s around me and do I know what it is? iNaturalist allows me to figure out what the things are that I’m unfamiliar with. They have a more ‘fun’ app called Seek that has monthly challenges and can identify organisms as you sort of pan over them with your camera! It’s a lot of fun to explore and learn and the same time.

I also knit scarves, I don’t do fancy patterns or anything besides scarves because the point of knitting, to me, is to clear my mind and keep my hands busy while we are watching TV or just relaxing. I choose to knit Harry Potter scarves because I love the series!! I first started knitting them almost a decade ago and have a little Etsy shop where people can purchase them if they want to. They are also really warm, I started making them when I lived in Chicago and it’s just a funny joke that I keep moving south and keep making them.

I have many other hobbies but those are the two that I really enjoy the most. I read books but not as avidly as I once did and it’s much harder for me than it used to be, I suppose it’s because my mind wanders more easily to get all of my other tasks done. I do yoga a lot, play with my cats, garden, play Pokemon Go, blog, and chat with old friends.

Adriane

Adriane and Scimmitar!

As I’m in the last year of my PhD and frantically trying to finish my dissertation, I don’t have as many hobbies as I should. Much like Sarah and Jen, I do enjoy reading novels (mostly fiction to balance out the serious-ness of sciencing), playing Pokemon Go, blogging, and hanging out with my cats and husband. When the weather is nice, I also enjoy hiking around western Massachusetts (there’s no shortage of awesome views here!). My husband and I have also taken up biking, which has been great incentive to get us out of the house and doing something physical! Often in the summer and fall, we bike down to a market down the road a bit for ice cream.

Honestly, my most guilty pleasure right now is Netflix and HBO, and cooking. There is nothing I love more than to come home after a long day at work (I’m currently averaging about 9-10 hour days in the lab, so when I come home, I don’t feel like doing much) and plopping onto the couch with my kitties and husband. I love to cook and experiment with different recipes, so I usually cook about 5-6 days a week. After that, my husband and I watch the latest TV obsession, which is usually a series (yes, we’re sad Game of Thrones is over, but hey, that leaves more time for re-watching other beloved series like Dexter!).

The aforementioned hobbies (if you call watching TV a hobby) are not always my ideal ways to pass the time, so I’ll let you all in on a little secret: I LOVE old cars! Before I left home for graduate school, my dad and I would work on my 1971 Mercury Comet, which my husband wittily named ‘Halley’ (like Halley’s Comet, get it?). My dad bought the car for me as my high school graduation gift, and we’ve been working on it ever since. My dad is a huge car nerd as well. He’s a machinist by trade, but I’ve never met anyone who knows as much about cars as him. He has rebuilt several engines, installed exhaust systems, rebuilt carburetors, you name it. Since I’ve had Halley, we’ve put in a new engine (a 306 cubic inch compared to the 289 that was in it), new rims, and lockers on the rear (lockers make both back tires spin at the same time). Eventually, I’d like to make the car a 4-speed, install bucket seats, and give Halley a paint job, as currently she is 3 different colors. As you can imagine, antique car restorations are expensive, so this is not an ideal hobby to have whilst one is in graduate school on a limited budget.

Adriane and her mom having an archery competition.

My other hobbies that I absolutely love to do but cannot in this phase of my life are gardening, horseback riding, tending chickens, and shooting (rifles and recurve bows). After that last sentence, you probably now realize that I was raised in the country and am a bit of a redneck. Currently, my mom takes care of my horse, Scimmitar, who I have had and ridden since I was in grade school. Scimmi is a 31-year-old Egyptian Arabian who has more spunk than any older horse I’ve seen. When I go back home to Virginia, I still take him on trail rides through the woods with my mom, my sister, and our other horses. My sister and mom love chickens as much as I do, and still have 8 as pets. The chickens are all different breeds, and are mostly used for bug control in the yard and a source of eggs. Recently, my mom did teach her hen how to play the xylophone! My mom is the one who actually got my husband and I hooked on shooting recurve bows. She learned from her friend, and actually taught a few classes at her local sporting goods store. Archery is great because it forces you to clear your mind and focus on your body. It’s a great stress reliever, way to build muscle, and learn to focus your attention. I enjoy shooting rifles with my dad and brother, but those are pretty noisy and not quite as good for centering yourself like archery 🙂

Academic Job Interviews

Jen and Adriane here –

Academic job interview season is always upon us and we wanted to give some perspective from our experiences. We have done phone interviews, Skype interviews, and in person interviews. More recently I, Jen, have had the opportunity to be on the other side of the table and do the interviewing. All of these experiences have given us a lot to think about and we would like to reflect on some of it for you all. 

Prepping for an interview

Jen: To prepare for interviews I had a series of steps. First, I would do some research on the university/museum/organization to figure out what their mission, goals, and vision are. I could use this information to figure out if I was a good fit and what about my own career goals align with theirs. I then go to the department/group website to get a sense of who might be interviewing me, in many cases you will get a list of people ahead of time. I would think about questions they may ask and answer them on a note sheet and then come up with a list of questions to ask them. 

Adriane: I was interviewed for two postdoctoral positions, and one tenure-track job. For the job, I did basically what Jen outlined above. I did research on each person in the department, such as where they went for graduate school, their most current and previous research interests, and any major on and off campus activities they were involved in. I then created a document with all of this information, with each page dedicated to that person. On that same sheet of paper, I also wrote down specific questions for each person. This way, I had everything I needed for talking to one person on one page, and I could also take notes. This method sounds like a lot of work (it really wasn’t), but it paid off immensely. Often, these on-site/campus interviews are tiring and you’ll be extremely nervous; do anything and everything ahead of time that will make the experience easier for yourself!

Below are some questions we encountered during job interviews (these were asked of us specifically for visiting or tenure-track professor positions):

Some questions you should prepare to answer:

  • Why do you want to work here? 
  • How would you/your research contribute to this department/job?
  • What do you need (such as equipment) to do research in this department?
  • What courses could you teach in our department?
  • How could you involved our students in your research program?
  • How could you collaborate with our faculty in this department?
  • Provide an example of an effective teaching method you use in the classroom. 
  • Describe your research. 
  • Describe how you teach/your teaching strategies. 
  • Outline a syllabus for a class you would teach (or they might ask you to do this for a specific class). 

Questions you should prepare to ask*:

  • How does the department support you (grad, faculty, staff) in your role?
  • What would the ideal candidate for this position bring to the department?
  • What sort of funds are available for students to engage with research or projects?
  • Are students encouraged to travel to conferences? Are there funds to help them?
  • Am I encouraged to travel to conferences?
  • What sort of internal funding support is available for my research?
  • Are there departmental service requirements and what would they be for my first year?
  • Do faculty support each other’s work? Is this a collaborative environment?
  • A good one to end on: Do you love living and teaching here, and why?

* It is always good to ask these questions to multiple people to see how answers vary within the department.

Phone Interviews

Jen: These are the most awkward for me. I take a lot of queues from facial expressions to keep conversations moving, so trying to figure this out without seeing is tricky. It also is harder for me to listen closely and take notes without the visual queues of someone speaking to me. My suggestion would be to wear headphones so you don’t have to hold up your phone, this will allow you to quickly take notes as people are speaking to you. Since you can’t tie names to faces, it’s best to have a list of people who will be speaking to you ahead of time so you can refer back to their speciality or position during the call. 

It may be worthwhile to use an online transcription feature like in Google Docs you can use Voice Typing. You’ll have to have the call on speaker but then you will get all of the questions people ask relayed in front of you. This is the other thing I struggle with – recalling multipart questions when on a call. Often you can’t write them down quick enough so you forget! But having a way to visualize the question again would be greatly beneficial and keep things moving. 

Skype/Video Call Interviews

Jen: I prefer these setups because having a visual of the interviewers really helps me. They can also be very awkward though – depending on the set up. Often, you will be projected onto a larger monitor and be interviewed by a conference room full of people. I have been interviewed by 1 to 6 people. This is tricky because if there is not a separate microphone it can be incredibly hard to hear the people interviewing you. That is okay, just be sure to notify them – they will likely ask if you can hear them and include something like, ‘you are a little faint’ or ‘could you speak up some’. These people will have a set of questions to ask you and often they will go around the room as certain people may have specific questions they are posed to ask each candidate. 

This can make it hard to identify who is who. I usually make a drawing of names or initials around a table so I can refer back to my cheat sheet of notes about the people interviewing me. This then helps place the people in the context of their role at the institution – which is super easy to forget when you are quickly being introduced to five people sitting around a table who are only ½ an inch high.

Be sure to have a quiet area to do the interview. Wearing headphones with a microphone ensures that they can hear you and hopefully you can hear them. I would also recommend a plain background or something simple so that the people interviewing you don’t get distracted and you are the main focus. I would try to have your face centered on the screen as much as possible without being cut off at the top or bottom of the screen. 

Similar to the phone interview, I would have a notebook adjacent to you so you could quickly take down some notes during the interview. Also, you can more easily use the ‘take a drink of water’ trick when they can see you drinking – unlike on the phone. If you need a second to ponder an answer to a question- take a sip of water and reflect then respond.

Adriane: In addition to what Jen said above, you should also find out ahead of time the format for the interview. For example, one of my postdoctoral interviews over Skype was in the format of about 10 minutes for a presentation and 20 minutes of questions and talking. This was helpful to know in advance, as I could prepare what I wanted to talk about and use slides to do so through screen sharing. Another important step you should take is to test your equipment before the actual interview with trusted friends or colleagues. I tested my Skype and screen sharing capabilities twice with friends. I’m really glad I did because the second time, my sound went out! Luckily I figured out the problem and was able to fix it far in advance. 

Because I work in a lab with several other people and I needed to be at my computer for the interview, I sent around an email to my lab mates to let them know the date and time of my interview.  I also put a sign on our lab door that read ‘Interview in Progress’ so people wouldn’t run into our office during that time. 

In-person Interviews

Jen: On campus interviews for faculty or staff positions can be much more involved. I’ve done two two-day campus visits and one one-day visit. Depending on the type of position you will likely be invited to give a talk – or two! These can be about a specific aspect of your research, your proposed research program to bring to the institution, your teaching experience and course offerings, or teach a course so they can observe you at the head of the classroom.

Prepare your mind: These are marathons. You will likely have a packed schedule of 30 minute meetings with all sorts of people. It is perfectly within reason to ask similar questions to a variety of people – in fact, you absolutely should! It will give you an idea of who is maybe talking up the department versus the reality of the situation depending on the answers you receive. 

Prepare your talks: Before starting, know your audience – meaning who are you speaking to? A room full of people who will understand exactly everything you say? That’s highly unlikely. Prepare background information to catch people up to speed. I have a set of background slides I constantly use to help people understand phylogenetic trees and how to read them. It’s best to set up your audience to understand your talk rather than to just spew information at them. 

Ask your colleagues, peers, friends, supervisors, anyone who recently went through the job interview life to send you their slides to see a structure or to set up a time to chat with you. I was advised to include citations for as many of my publications as possible on the slides. Showcase work done with undergraduate researchers to show the audience your commitment to their student body. 

Extra things to bring: For my first on campus interview I tired to be really prepared. I often don’t travel well so I made sure to bring aspirin and tums. I also tend to not sleep well or get cramps from sitting funny on the airplane so I always carry Icy Hot or similar muscle relaxer when I travel. Bring things that you need to be comfortable because you are likely to experience some discomfort. 

I always had a water bottle with me, I get really dehydrated so I figured this would help. None of the interviews I have done allowed flex time for bathroom breaks. This means you often have to request to use the bathroom or get a refill of water – you definitely should request these breaks!! It helps to just be quiet for a few minutes in a cold place before jumping back into conversations.

Adriane: For my on-campus interview, I did basically what Jen outlined above. I did research on each person in the department, such as where they went for graduate school, their most current and previous research interests, and any major on and off campus activities they were involved in. I then created a document with all of this information, with each page dedicated to that person. On that same sheet of paper, I also wrote down specific questions for each person. This way, I had everything I needed for talking to one person on one page, and I could also take notes. This method sounds like a lot of work (it really wasn’t), but it paid off immensely. Often, these on-site/campus interviews are tiring and you’ll be extremely nervous; do anything and everything ahead of time that will make the experience easier for yourself!

Second, I took the time to really get to know the department through news articles, their website, and through colleagues (our department head and one of my friends did their undergrad at the college I interviewed at, so they were great resources!). I did this while watching TV at night, and it became kind of fun. It also paid off, as I was able to ask questions about events and initiatives at the college which got people talking more. 

Third, I’ll emphasize what Jen said above about knowing your audience and preparing for your talks. When I did my on-campus interview, I was asked to do a teaching demonstration and a research talk. The college where I interviewed was undergraduate-only, so I knew I had to tone down the complexity of my research. I’ve taught a ton of undergraduates, so the teaching demonstration was fun and easy. I spent the most time on my job talk, which involved modifying figures that I had previously made, culling out very jargony words specific to my field of research, and providing enough background information for a general audience. I also used graphics to explain my science. I create a lot of geochemical data, which are basically just squiggly lines plotted against geologic time. To make the interpretations from these squiggles more appealing and contextual, I created models of my interpretations. These models likely won’t become published in a paper because I don’t have enough data to support them, but they were perfectly fine to illustrate my science and communicate that to a more general audience. After my talk, even the biologists who sat in said they understood everything and thought my research was really cool! So taking the extra time and effort to readily and easily communicate your science in well worth it!

A figure from my paper showing increased evolution correlates to cooling global temperatures and tectonic activity, but this was created for other scientists.
The modified version of the above figure that I made for my job talk, which was to a room full of undergraduate students. Here, I’ve cut out some data and added in colored bars and gradients to help guide people’s eye to better see the trends.

 

Fourth, be prepared for your schedule to get shifted around. My on-campus interview was during the Deep Freeze of early 2019, when temperatures in Michigan got into the -40’s with windchill. This led to the college closing, which rarely happened. This also meant that my two talks, instead of being on two separate days, were 30 minutes apart. I was totally fine with this, as I had practiced both talk to the point of almost boredom, and I had practiced them back-to-back (just by chance). 

Lastly, just be yourself and have fun! I’ve received A TON of interview advice over the years, but this has to be the best one. For every interview I’ve had, I just go in being myself and bring my full enthusiasm for my science. For the talks I gave during my interview, I made them fun not just for my audience but for myself as well.

An example of images from my teaching demonstration, where I got some laughs. Who doesn’t like cake and pictures of kids with cake on their faces?!?

As far as packing for the interview, I packed several different outfits (I tend to change my mind a lot, so I wanted to give myself some flexibility and freedom on wardrobe choices). I have curly hair, and have to use mousse otherwise I look like a Chia pet. I didn’t want to check my bags in the airport for fear they’d get lost, which meant I couldn’t take my beloved mousse brand. So I spent a few hours tracking down a travel-sized mousse I could take with me the week before I left. I even tested it out beforehand to make sure I was happy with it. So, don’t be afraid to take the extra time and initiative to pack what you want and what will make you comfortable. I’m so glad I didn’t try any new hair products while I was interviewing, that would have just added to the stress. I also bought myself a new leather bag that made me feel like a professional and adult. Just having this helped my self-confidence, and it allowed me to be more organized (I tend to just throw everything into my bookbag).  

Most importantly, don’t be afraid to advocate for yourself during your interview. It just so happened that while I was traveling to the interview, I started my period. For me, this means ibuprofen every 6 hours or else I feel dead. So I made sure to tell folks that I needed to use the restroom when I had to, and also when I needed to get back into the department head’s office to grab more Advil from my bag. There’s no reason to pretend your not a human with basic needs during these interviews, so don’t be afraid to ask for bathroom breaks, water, or whatever else you need!

Evaluating candidates

Jen: While I was at the University of Florida, I helped with the hiring process for two positions. The first was a staff position with over 50 applicants apply to join our core team. Our core team is really small, there are only five of us and three of us were part time. So we all evaluated each of the 50+ candidates, this means we looked through the submitted materials and online form. We had requested each applicant include a resume, cover letter, and list of references. Since there were so many candidates, those that did not follow instructions (such that they missed one of the required documents), we excluded  their application. We used the original job advertisement to look for specific aspects that the candidates could help us with and ranked them but this was only part of how we determined best fit. We also took into account education versus experience, how well laid out the resume was, and how well written the cover letter was. 

From this we pulled out just over a handful of candidates to investigate further. First, we re-read application packets and then we called their listed references to ask them a series of questions. We decided upon the questions we would ask ahead of time so that each of us got the same information – or close to it – for each candidate. We then hosted Zoom interviews with all the candidates that passed our reference check. This was usually about 45 minutes on our end 30 minutes on the candidates end. Something that is hard to avoid were technical issues. The first candidate we couldn’t get projected up onto the big TV so we all had to strain our eyes to see them on a laptop – we had to do this with the remaining candidates as well to be fair.

Ignoring my strange face and poor quality image, notice the background of the image. Your eye immediately wanders from me, the focus of the interview, to the miscellaneous things around my office.
Okay, again ignoring my strange face you see there are much less distractions in this image with the plain background. So your focus remains on my strange expression.

But it brought up some key things – be front and center with a plain background behind you. This will help the interviewers be able to see you very clearly. Use a microphone outside of the one in your computer, this greatly cuts down on background noise and the interviewers are likely in an echo-y room so anything you can do to reduce it will be easier on them. Speak slowly and deliberately, there is not a rush and when you speak fast (not always avoidable) sometimes it’s hard to keep up. Mostly because there are a few people in a large room trying to focus on a small screen – it’s a bad situation. 

We then had a meeting to decide upon the top candidates to bring to campus for an in-person interview. We spent half a day with each candidate working to get to know them better. We had a group discussion where other members of the museum staff could come mingle and ask questions and then a more formal interview with the core team. These were more conversation led with a few major points we wanted to make sure to hit along the way. These points could be items from the candidates resume or cover letter that we wanted more information on or from something in the first interview that we needed clarification on.

Hopefully these hints are helpful and best of luck on the job market!

NAPC Teacher’s Workshop in Digital Paleontology Resources

FOSSIL’s newsletter article: https://www.myfossil.org/digital-resources-in-paleontology-professional-development-workshop-napc2019/


 Jen and Adriane here – 

As part of the North American Paleontological Convention, there was a teacher workshop all about sharing digital resources in paleontology. This was hosted by the FOSSIL Project (which employs Jen) and iDigBio with many participating partners. We advertised the workshop about two months in advance and had a webpage with information for the applicants – we were targeting local California teachers. The primary goals were to (1) Raise awareness of resources available for teachers associated with digitized paleontological collections; (2) Connect teachers with a network of professionals, to help them develop and implement collections-based curricula; and (3) Increase confidence in teaching about global change and evolution using fossils.

Jen (front left) and Adriane (front right) teaching teachers about the wonderful world of foraminifera.

The day was structured in seven hour blocks. Each presenter had ~20-30 minutes to introduce the platform, provide background content, and explain the utility of the resource. This was then followed by a ~30 minute activity using the resource. We wanted the workshop to allow educators to immediately take content back to their classroom to employ but it’s always best to do a test run so the educators and facilitators can brainstorm modifications or limitations within their own classrooms. You can see a full agenda for the day by clicking here.

We were specifically involved with the presentation on the Digital Atlases of Ancient Life. When we were working on our MS degrees with Alycia Stigall we were both employed as an RA on this project for one year. Jon Hendricks led off our hour block with a presentation explaining the atlases that are available, the Digital Encyclopedia of Life (DEAL, a free online textbook), and the Virtual Teaching Collection. Alycia followed with a short presentation on Paleozoic life and assessing ancient ecosystems. And then we used the Virtual Teaching Collection to work to identify some of the major animal groups that were around during the Paleozoic. We helped facilitate the lesson and answered any questions the educators had. 

We also led our own presentation later on using myFOSSIL tools in the classroom. Sadie Mills led off with an overview of myFOSSIL and all of the capabilities of the website and mobile app. Adriane followed with a presentation on how foraminifera are the most awesome creatures to ever float on Earth. And then we walked through a lesson on using foraminifera as a tool to think about morphological shape and how they may have lived in different environments, and we provided other lessons for the teachers to think about forams as a tool for understanding climate change. 

Overall, the workshop was a huge success and the participants really learned a lot and got to have lots of in depth conversations with facilitators! All the materials from the workshop can be found on the myFOSSIL website.

Applying to Grad School IV: Interviews

Members of the Time Scavengers team are writing a ‘Applying to Grad School‘ series. These blog posts are written primarily for undergraduate students who are applying to graduate programs (but will be useful for any transitioning graduate or professional students), and will cover such topics as funding and stipends in grad school, how to write and build a CV, how to craft an email to a potential advisor, and how to effectively write statements for your applications. This is the fourth post in the series on how to effectively interview with a potential graduate school advisor.


Adriane and Jen here-

This post is all about interviewing for and visiting potential graduate schools as an undergraduate student in your senior year or as someone deciding to go back to college. This can be a VERY scary process, as it involves talking with high-profile scientists in your field of study and answering questions about your science, education, and interests. Below is some advice from our own experiences, some things you should do to prepare for an interview and/or on-campus visit, and some questions we were asked by potential graduate school advisors. 

Interviews

First, there are several different types of interviews you may be asked to do as a student. In-person, online (usually through a video chat platform such as Google Hangouts,Skype, or Zoom), on-campus, or on the phone

In-Person

In-person interviews can be done through a visit to the potential advisor’s campus or at a meeting that you are both attending. You should request an in-person meeting at a conference during your first few email exchanges with a potential advisor (see our “Applying For Grad School Part III: Emailing Potential Advisors”). Simply, conference meetings are easiest when you set them up beforehand. When I, Jen, was looking for PhD programs, I requested to meet with three potential advisors at the large geology conference the fall I was applying to programs. This allowed me to also meet with other lab members – students and postdocs – so that I could ask them questions about their experiences with the advisor. 

I, Adriane, asked to meet with two potential advisors at a large geology conference I was presenting research at during my senior year of undergrad. I told each person when and where I was presenting, and asked them to come there to talk with me. I did this so they could get a clearer picture of what my research was, and so they could ask me questions about my goals and such. I had two potential advisors come by my poster (both also had excellent feedback), but one was busy during that time. Instead, she and I sat down together and chatted informally for a few minutes.

Some things I, Adriane, did to prepare for our sit-down meeting at the conference was print out a copy of my poster and my CV to give to my potential advisor. I also had a notebook with me and several pens to take notes (because if you only take one pen, it’s sure to die or be dead). I also dressed appropriately for each interview, meaning I wore something comfortable but also professional. 

On-Campus

In some cases, the institution or advisor will help support your visit to their university, most after you have had an in-person or phone interview first. Many universities have funding to bring out PhD students, but not MS students – this is entirely school dependent. It is within reason for you to ask if there are funds to help offset travel, especially if it is not easy (or cheap) for you to get to the university. Current students will often host you as their guest so you can have more in depth conversations with someone in the program. Just note that most schools will reimburse you for your travel- meaning you will, unfortunately, have to front the costs for travel. 

Once I, Jen, was accepted into a program – I requested a visit to the campus. My visit ended up being in February and I was close enough to drive the 5 hours. I stayed with a current student (Sarah) so there were no lodging expenses and was able to get my gas mileage reimbursed. Visiting the campus was eye opening, I got to see students working in their spaces, talk with all sorts of faculty, and get a general feel for the atmosphere of the department. For the on-campus visit, I came prepared with some questions for students, faculty, and my potential advisor and ideas about projects I may be interested in. Remember, you are interviewing the school and you should question everyone you come across about their experience. If you have specific needs, make sure the school will provide them for you.

I, Adriane, did two on-campus interviews for my MS degree. I was invited to visit after I did in-person interviews at the geology meeting, and had been accepted to one of the schools. Both visits were nerve-wracking, but I highly recommend, if possible, doing an on-campus interview with your potential advisor. Doing so made me realize which advisor was the best fit for me and my career goals, and which school and city I would be most comfortable in. 

Online

Online interviews are very similar to in-person interviews. There’s a few extra steps you should do to prepare for your online interview before the big day:

  • Test out your equipment. Make sure the microphone, camera, and software all work before the interview. In fact, do this at least a week prior, as this will give you time to troubleshoot any issues that may arise
  • Find a quiet space to interview. Noises in the background will distract yourself as well as the potential advisor
  • Make sure the background is clear. Excessive clutter behind you (posters, books, shelves, other humans, etc.) will cause a large distraction. You want your potential advisor to focus on you, not your cat swatting flies or something in the background

Phone Interviews

To me, Adriane, phone interviews are the worse. I like to be able to see the person I’m talking to, as I respond better to visual cues. When you’re doing a phone interview, just be sure to find a quiet spot where you have good service and won’t get interrupted. Also, be sure to listen closely, as you don’t want to cut off, talk over, or interrupt the person interviewing you. 

TL;DR: Preparing for an interview regardless of the format (online, phone, in person)

  • Start by exploring the faculty and student page of the institution you are interested in, write down people that are somehow related to your interested and include a bullet of their interests and any questions they may be able to help you with. Jen suggests asking the same question multiple times to see the variation in responses – it can be very telling! You can bring a folder, clipboard, portfolio, notebook – whatever you are able to best take notes on.
  • Ask faculty at your current institution if they know people there or have any suggestions on people to meet with that may not be on your list. 
  • Decide how you are most physically comfortable. Jen usually wears dark jeans and a nicer sweater or shirt but is uncomfortable dressing up so often chooses not to. 
  • If you are doing a visit, be sure to have a separate list of questions for grad students – you will likely be taken to lunch or have some alone time with a few students. This is an opportunity to request honest feedback about how they are supported by the department and university. I, Adriane, made my decision on which MS program to attend based mostly on answers and experience from graduate students. 
  • If you are doing a virtual meeting make sure to get to a quiet place, use headphones, and try to have as plain of a background as possible with minimal glare. It seems silly but it can distract the person on the other end and you want them to be fully tuned into you!

Interview questions we were asked (at conference meetings and during on-campus interviews):

  • What is the bedrock under (current undergrad institution), and what is its age? (These questions are meant to test your geologic skills and knowledge, so any variant of this could pop up) 
  • Why are your GRE scores so low? (This really is not an appropriate question, but some professors are bold enough to ask anyway – Jen was asked this during her visit to UTK and Adriane during her visit to a NC school)
  • What are some of your personal goals during your (MS/PhD) degree?
  • What are your research interests?
  • Describe your research experience. 
  • Would you be comfortable teaching in a lab or classroom setting? Do you have teaching experience?

One last note, it is hard to remember this but the department is trying to sell itself to you. They want excellent students to help increase their output numbers. At some points you’ll realize it sounds like an info-mercial. They want you to choose them, even if you don’t have other options (don’t tell them that) they will still try to recruit you.

Applying to Grad School II: Preparing your CV

Members of the Time Scavengers team are writing a ‘Applying to Grad School‘ series. These blog posts are written primarily for undergraduate students who are applying to graduate programs (but will be useful for any transitioning graduate or professional students), and will cover such topics as funding and stipends in grad school, how to write and build a CV, how to network with potential graduate advisors, and how to effectively write statements for your applications. This is the second post in the series on how to prepare and structure your CV for graduate applications.


Adriane and Jen here –

A good starting point for gearing up to find a STEM* (science, technology, engineering, math) graduate program is to get your Curriculum Vitae (CV) looking good. There are a variety of ways to do this in a handful of programs that may or may not give you templates. When emailing people about working with them in the future it is customary to include your interests and your CV so they can look at your experience. A CV should document all of your academic credentials, accomplishments, outreach and service, publications (of all types), and more! Read this online resource to learn more about how CV’s and resumes differ.
*because we are all geoscience majors, the advice that follows is mostly applicable to STEM majors, check out CVs of people in your field by looking on their websites & research gate!

The additions to your CV all depend on what you are applying for and wish to do. If you are interested in a museum position, it’s a good idea to add when you have worked with collections, in what capacity, and for how long. Similarly, if you are applying for tech positions in a lab make sure you list out the equipment you have experience with and what you did with the machines. When applying for graduate schools specifically, what you really want to show is that you have a good, solid education, and that you are hard-working and can achieve tasks and goals.

We’ll go over some sections that should be included on your CV, but here are some general tips that apply to the entire document:

  • List the most important information first (Education, Professional and Work Experience), then go from there
  • Make sure the date for each item is very obvious and clear; provide a range of dates (e.g., 2013–2015), a year (e.g., 2016) or a specific semester (e.g., Fall 2015) for each item
  • Use italics and bolding, but do so in a manner that is appealing and does not distract from the overall appearance of the document
  • Make sure the text and any bullet points are aligned correctly throughout the entire CV
  • Use language that can be understood by the general public and doesn’t contain too much jargon; you don’t know who will be reviewing your application
  • Pick one font and stick with it
  • Using different sized fonts throughout is ok, but like italics and bolding, be sure this doesn’t distract from the overall look of the document
  • List your achievements (and other chronological things like community outreach, mentoring, etc.) in order from most recent to oldest last

As a disclaimer before diving into this post, we have been at the academic game for a long time. Do not feel discouraged if you don’t have as many lines on your CV. There are a million opportunities for you to expand your horizons and engage in research, award nominations, grants, and much more as you continue along your academic journey!

Document Header

The heading on your CV should include your name, address, and contact information. Generally, your name can be in a bigger font so the reader is drawn to that first. You can list your home address, or the address to your university. I, Adriane, always include my phone number, email address (make sure it’s a professional email address), and my website URL. It is important to make sure you are using the designated header space on your document, as this ensures you have more space on each page of your CV. There are settings that allow you to have a different header on all subsequent pages so the first can be large and then you can switch to just your name so the person reviewing it doesn’t lose track of whose CV it is. Here’s an example of a formal header:

I (Adriane) also jazzed up my CV by adding in images of fossils that represent the two major time periods I work in. Stylistic features like this may be considered as unprofessional by others. So, ask those in your lab group or your supervisor/advisor for their input before doing something like this.

Education

The first section of your CV should be all about your education. Here, you’ll specify where you attended high school (or leave it off, it’s up to you) and the college and/or university you attended for your undergraduate degree. Within this section you can also include your overall GPA. If you are attending graduate school to further your e.g., geology undergraduate degree, you can also put your major GPA. I, Adriane, did this when applying for graduate programs because my total GPA was low, but my geology GPA was pretty high. Within this section, also be sure to include the dates for which you attended each institution. If you did an undergraduate thesis or research project, you can even include that information in this section. Here’s an example:

An example of Adriane’s Education section from her CV with her undergraduate thesis and advisor information included.

After this section, you can tailor your CV sections to best fit you, the position you are applying for, and your experience. As an undergraduate, it’s important you showcase your experiences and capabilities.

Professional and Work Experience

The next section on your CV could be ‘Professional and Work Experience’. Here, you can add in any formal or informal positions you have held. For example, if you volunteered as an undergraduate teaching assistant, you could add that to this section. If you held any jobs, add those as well! Jobs that showcase team building, management, and other useful life skills are important to add even if they aren’t relevant to your target job or career. Some academics will tell you to leave off jobs that don’t have anything to do with the degree you are seeking in graduate school. I, Adriane, still include the two assistant manager retail positions I held while going to community college. I worked hard at those jobs, and including them on my CV (hopefully) signals to others that I have leadership experience and have extensively worked in teams to accomplish tasks. Both of these qualities are important in academia, although they are hardly talked about. Adding in these other professional experiences also helps fill out your CV if you are really early in your career path or haven’t found a position that will pay you for your scientific expertise  (as many lab positions are volunteer based).

Peer Reviewed Publications and Conference Abstracts

One of the next important sections you should include on your CV is any abstracts you authored or were included on for academic meetings. If you contributed to a peer-reviewed publication go ahead and include it here. It’s important to be consistent with the style you cite publications and abstracts in this section because it can look messy or be confusing otherwise. This section highlights that you’ve been involved with research, and have practice presenting your research to the scientific community. If you don’t have research experience, don’t fret! Many undergraduates who apply to graduate programs don’t have that experience just yet, and that’s ok!

An example of Jen’s Publications section from her CV, this is a subheader specifically for Peer reviewed articles. In this same section she includes a separate subheader for Conference abstracts.

If you have any other types of reviewed literature you can also include it in this section. Maybe you helped edit something for a companies big annual report or contributed to a local journal or newsletter. Writing is a really difficult skill to acquire and if you can showcase you have been practicing that is great!

Funding and Awards

Next, list any funding you have received for any research projects, events, or clubs/associations you were involved with. You can title this section something like ‘Funding Awarded’. This section shows your future graduate school advisor that you can win money (a very important skill in STEM fields). In the heading, be sure to include the total amount of money that you’ve won to date. Each item in this section should also include the amount for each award. It may not seem like it, but if your college/university has helped you pay for attending a meeting, that’s money you should include in this section as well!

An example of a funding section from Adriane’s CV. Notice the total amount won is included in the heading, and then each item has its own funding amount.

If your CV is not super filled up it’s totally fine to combine sections. I, Jen, often suggest students to include funding and awards together – the heading could be funding and awards, achievements, whatever you think best describes what you are putting in the section. When you end up with more funding and/or award success it makes sense to split them into two sections so you can keep track of things. I called my Awards and Honors and also included any instance where I guest lectured for faculty members. I didn’t have another good place to put it in my subheaders so this seemed reasonable to me.

Example of Jen’s Awards and Honors section on her CV, which includes departmental and club awards as well as guest lectures for departmental classes.

Relevant Coursework

The next section you could include on a CV is any relevant coursework. For example, when I, Adriane, applied to paleontology programs, I included all the courses I took that were related to paleontology in any way (biology, invertebrate paleobiology, stratigraphy and sedimentology). Here, you can include the semester you took the course, and even a short two-sentence description of the class. If you gained specific skills in the class, it is best to include that in the short blurb. If you took a mineralogy course and also had the opportunity to prep and analyze samples for XRF or XRD, include that information!

Other Relevant Experience

The next section of your graduate school CV could include a section titled ‘Field Experience’ (or ‘Field and Lab Experience’, or ‘Lab Experience’). This section highlights the work you’ve done in the field/lab, when you did that work, and a short description of what it was you did. This section shows your future graduate school and advisor that you know your way around the lab or have experience doing science outdoors. Again, if you don’t have this experience, it’s not a huge deal!

An example of how to write and format a ‘Field and Lab Experience’ section on a CV. If you also have experience working with museum collections, include that in this section as well!

I, Jen, have titled a similar section more broadly as ‘Research Experience’. Here I include when I worked with (1) specific fossil collections; (2) specialized equipment or instruments; (3) any other things that may not have fit within the job descriptions listed above but may be useful for potential advisors or PI’s to know about.

Example of a ‘Research Experience’ section in Jen’s CV. Simple and concise phrases indicating what I did when then people can match it to specific time periods in my academic training.

Academic and Community Service

After you’ve highlighted your education, work experience, the research you’ve done, and your coursework, there are a few other sections you can include on your CV if you have the experience. If you’ve won an award as an undergraduate student, include that in a section titled ‘Awards and Honors’. If you are part of an organization, for example, president of the Geology Club, that can be included in a section titled ‘Academic Service’. Academic Service is any activity you do within the science community as a volunteer. This differs from Volunteer Experience as these are things done outside of academia. While we’re talking about it, do include a section on your CV where you highlight any volunteer or outreach experiences you have. This could be as simple as talking to a K-12 class about science, or helping at a rock and fossil sale.

Professional Memberships Organizations

The last section on your CV should be titled ‘Professional Memberships and Organizations’. This is where you will list all the clubs, organizations, and associations you are a part of. This shows that you are an involved and active member of your scientific and local community, a networking skill that will become even more important in graduate school!

Other Potential Headers

The National Science Foundation has a series of headers in their short format CV requirements and I, Jen, have worked to adopt some of the language that this large organization uses. So, I have a big header called ‘Synergistic Activities’ this includes, programmatic events I organized, ways I engage my community, professional development opportunities that I’ve participated in, professional service, mentoring experience, and invited talks and lectures. Now, that’s a whole lot of stuff but the header is something that people may specifically look for when they are analyzing your CV.

I also have a section called ‘Courses taught as instructor of record’. This is handy when applying for teaching positions because right off the bat they can see that I have taught a full course and have experience in front of a class. I have another section for ‘Collections Curated’ this is for specimens that I took care of or managed in some way. As I was applying for museum and faculty positions, it was to by benefit to include this section and showcase what I had done.

Example from Jen’s CV of the language used to describe the collections curated during my various positions.

Summary

Our last bit of advice is to seek out help with your CV! Reach out to your classmates, a trusted professor, or a graduate student for feedback. Your CV will likely go through several iterations until you end up with something you are happy with. Also, attend any resume or CV-building workshop on your campus or in your community if you can. You’ll likely receive additional advice than what we provided here, and also get really great feedback from others on your CV. And remember, your CV is a living document, meaning you should continually update it anytime you achieve something!

Applying to Grad School I: Paying for Your Graduate Degree

Members of the Time Scavengers team are writing a ‘Applying to Grad School‘ series. These blog posts are written primarily for undergraduate students who are applying to graduate programs (but will be useful for any transitioning graduate or professional student), and will cover such topics as funding and stipends in grad school, how to write and build a CV, how to network with potential graduate advisors, and how to effectively write statements for your applications. This is the first post in the series on various ways you can get paid to attend graduate school in STEM (science, technology, engineering, math) fields.


Jen, Adriane, and Sarah here –

Attending graduate school is an exciting prospect, but you can quickly become overwhelmed with deadlines, things to do, but mostly by the expense of it all. It’s no secret that today’s college undergraduate students are facing increasing tuition costs along with inflated interest rates on loans. Within public 4-year universities and colleges alone, tuition and fees rose on average 3.1% per year from the period of 2008 to 2019. Even within 2-year public colleges (such as community colleges), tuition and fees rose on average 3.0% per year within the same period of time! For student loans, interest rates range from 4.5% to as high as 7%, and that interest is usually compounding (meaning you will pay interest on the interest that your loan accrues over time). It can seem like there’s no way to escape college and obtain an education without paying dearly for it, especially if you want to attend graduate school right or soon after your undergraduate degree.

But fear not, there are several ways in which you can avoid taking out loans while pursuing a graduate degree, both MS and PhD. Since we are all geoscience majors, the advice and information we provide herein is more applicable to graduate degrees in STEM (science, technology, engineering, math) fields. Below, we discuss a few options to reduce the cost of attending graduate school. We also are very transparent about the debt we accrued during our undergraduate degrees and how that compounded over time. But mainly, we want to explain how you can get paid (yes, you read that correctly!) to go to graduate school.

First, we’ll discuss the different types of assistance you can be granted to go to graduate school. We’d like to stress that we do not advocate for paying for graduate school out of your own money if you’re majoring in a STEM field*, as you should be able to get an assistantship to pay for your tuition and provide a stipend (living expenses)**.
*we’re uncertain about non-STEM fields-please look for good resources to help you understand how tuition waivers and stipends work in other fields!
**some STEM industries will pay for their employees to go back to graduate school. This is an awesome option, but not available to everyone.

Assistance within the University

Teaching Assistant

Teaching assistants (TA for short) are graduate (MS and PhD) students who are paid to help teach classes and labs at their university. For example, Adriane taught Historical Geology lab sections at UMass Amherst, and had a blast doing it (so many cool field trips!). As a teaching assistant, you will also be involved with setting up experiments for labs, grading students’ assignments, helping on field trips, or even leading your own field trips! Being a teaching assistant can be a ton of work, but it is a great way to make money and sharpen your skills as an educator (important for folks who want to continue teaching in any capacity after their degree). There may also be opportunities to continue working as a TA over the summer, as these jobs usually do not include summer stipends.

Teaching assistantships often include tuition remission, meaning you are not expected to pay for your education. This is important when you are looking for graduate positions in the university. You want to ensure that you are receiving a stipend and tuition remission. Even though you are getting your education paid for there often are still associated fees you have to pay each semester. These fees can range from 100’s to 1000’s of dollars every semester and cover transportation, athletic, heath, and building fees on campus.

Research Assistant

As part of her RA as a master’s student, Adriane helped curate and digitize a fossil collection at Ohio University.

A research assistant (RA) are graduate students who are funded to do research or work on some aspect of a project. Usually, the money to fund an RA comes from the student’s primary academic advisor, or it could come from some other professor in the department. In most cases, an RA is only funded during the academic year, but it’s not uncommon that money for an RA is budgeted to fund the student over the summer. For example, Adriane and Jen were each funded for an entire year from their MS advisor’s NSF (National Science Foundation) grant, where they were able to build a website while working on their own research. The benefit of RA positions is that they are usually more flexible as to when you can get your work done. When Adriane was doing her MS degree as a research assistant, she would spend an entire two days of the week doing RA stuff, that way she had huge chunks of time to focus on her research. The downside to being an RA is that you don’t receive teaching experience or get to interact with students in a formal setting. This isn’t a huge deal, as there are usually opportunities to help professors out teaching their courses while they are away at conferences, doing field work, etc.

 

Internal University or Departmental Fellowships

Internal fellowships (and grants) are small to large pots of money that you can win from within your university or college. You have to do some research and keep up with deadlines on these because often they have specific requirements. While Jen was at UTK there were several extra fellowships you could apply for as a graduate student. Some were specifically for MS students others for PhD students – some were mixed! One was only for students in their first year and one was only for students in their last year. Jen was fortunate enough to apply for an receive a fellowship through the university to fund the last year of her dissertation. This allowed her to reduce her teaching load and focus more on writing. You can read about it by clicking here.

External Funding Options

External fellowships

There are fellowships, like NSF’s Graduate Research Fellowship Program (GRFP for short)-you write a proposal for the research you want to work on and submit it. It’s reviewed by experts in the field you want to specialize in. These are incredibly competitive across a national or even international scope, but they are great ways to fund your research! Often, you have to apply to these either before you begin your graduate program or early into your program, so look into it as soon as possible!

There are other options to acquire competitive fellowships, often to finish off your dissertation without being restricted by teaching or other responsibilities that take time away from completing your projects. NASA has a program that graduate students can apply for, but there are restrictions – you already have to be enrolled and your project has to fit whatever the theme of their solicitation is that cycle. Adriane won a similarly competitive fellowship for foraminiferal research, which you can read about by click here.

Tuition Remission/Waivers

In some jobs and careers, your employer will reimburse your tuition costs. These are often to benefit your employer, as investing in your education and training will make you a more well-rounded and specialized employee in your field. The amount that your employer will reimburse you also varies; some may provide 50% remission or 100%. This amount can also vary depending on the number of courses you take during your graduate career. If you think your employer offers tuition remission, it is best to have an open and honest conversation with them about how much they will reimburse you for, and how many classes or credits they will cover.

The Cost of Graduate School: Examples

Below is an outline of how each of us paid for our undergraduate, masters (MS), and doctor of philosophy (PhD) degrees.

Jen

Jen exploring Ordovician life with young minds at the Paleontology summer camp at the McClung Museum.
Undergraduate: Once I left home I was given access to funds from my parents that I could use to pay for school. I lived in the dorms my first two years which used up a lot of this money. I then moved into an apartment and took up three part-time jobs (lifeguard, gym manager, research assistant) to maintain my living and school expenses. This allowed me to save the remainder of the money in my college fund and use it to move to Ohio for my MS program.
MS: My first year at Ohio University I was a TA. My first semester I taught lab for Introduction to Paleontology and my second semester I taught Intro to Geology and Historical Geology. My second year I was on an NSF grant as an RA and worked on the Ordovician Atlas project for Alycia. Both summers I was awarded summer pay through this NSF project. My pay at OU was ~$14,000/year. My student fees at OU were ~$600/semester (summer was less like ~$200). Instead of taking out loans I took advantage of a loophole and paid late. There was a payment system but it cost extra. There was no fee (at the time) for simply paying a month late. It took some serious budgeting but was possible to slowly save for these extra fees.
PhD: I was a TA all four years at UTK and taught a variety of classes: Intro to Paleontology, Earth’s Environments, Earth, Life, and Time, Dinosaur Evolution. During my time here my department stipend was $15,000 and I earned another $5,000 annual award from the university. I was able to split my pay over 12 months rather than 9 months. I was also able to work extra jobs over the summer at the university to augment my pay. Year 1 I was TA for a 4-week summer course for an extra $1000. Year 2 I taught a 4-week summer course as instructor for $3000. Year 3 I taught governor’s school (4-week program for high school students) for $2000. Year 4 I taught a paleontology summer camp at the local natural history museum for $500 (but also had the fellowship, where I got $10k but was reduced teaching so only received $7.5k from department).

Sarah

Undergraduate: Full need based scholarship (shout out to UNC Chapel Hill for making my education possible!). My scholarship covered everything but summer school for the most part and I was hired as a federal work study student to pay for books and other necessities. I worked other jobs at the same time-I worked as a geology tutor and a lab instructor, namely, to cover other needs (medical care that wasn’t covered by insurance, transportation, etc.). I took out $7,000 in federally subsidized (i.e., interest doesn’t accrue until you begin paying) to cover summer classes and a required field camp.
MS: I was paid as a half RA/half TA for one semester. I worked the remaining 3 semesters as a full TA teaching 3–4 lab courses per semester (I was paid extra to teach in the summer). My base pay was $14,000/year in Alabama. I worked as a tutor for the athletics department one summer to help pay for groceries. I did not take out loans for my degree, though I was not able to save much money.
PhD: I was an RA on my advisor’s NSF grant for 2 years and a TA for two years. I also worked as a TA or a full course instructor for 3 of the 4 years. My base pay was $15,000/year in Tennessee. I took out $15,000 total in federally unsubsidized loans (i.e., loan interest began accruing immediately) to cover unexpected medical, family, and car emergencies. I also did small jobs, like tutoring individual students, helping professors, and babysitting to make a little extra money-my PhD department had a rule that we weren’t allowed to work outside tax-paying jobs on top of our assistantships.

Always looking to find that extra dollar in graduate school.

Adriane

AS (Associate of Social Science): I spent four years in community college, and lived at home while doing so. I worked 20–30 hours a week at a retail store to pay for courses and books. My grandmother did help me significantly during this time, so I was able to save up a bit for my BS degree when I transferred.
Undergraduate (Bachelor of Science): I took out loans for 3 years worth of classes and research at a public 4-year university, in total about $40,000. I received a research fellowship ($3500) to stay and do research one summer. I still worked at my retail job the first summer and on holidays to make some extra money.
MS: The first year I was a teaching assistant and my stipend was about $14,000 for the year. Over the summer, I won a grant from the university ($3000) that covered rent and living expenses. The second year I was a research assistant and made about the same as I did the first year. I think I took out about $5,000 worth of loans to help cover university fees and supplies.
PhD: Throughout my first 3.5 years, I was funded as a teaching assistant making $25,000 the first two years, then was bumped up to $28,000 the third year (the teaching assistants at my university are in a union, so we won a huge pay increase). For the last year of my PhD, I won a fellowship (click here to read about it) from a research foundation ($35,000) that pays for my stipend, research expenses, and travel to research conferences. Early in the degree, I took out about $5,000 worth of loans to help cover fees and supplies.

Microplastics Alter Plankton Poop

Summarized by Adriane Lam

The Problem: There is a growing body of research that shows that microplastics, tiny (1um-5 mm) pieces of plastics, have made their way into the deepest reaches of our oceans and are being ingested by marine life. Microplastics ingested by animals have been shown to cause adverse health effects to them, but as consumers of marine animals, these same microplastics are making their way into our diets. As yet, we do not know the exact ways in which microplastics can affect human health on longer time scales.

Zooplankton, which are small animals and protists that float in the water column and feed on primary-producing phytoplankton, are an important link between phytoplankton and other, larger animals. Zooplankton make up the base of the food chain, and are the main food source of marine mammals such as blue whales.

One type of zooplankton is especially common in our oceans today. Copepods are marine crustaceans that are found in nearly every freshwater and saltwater habitat. In addition to being an important food source, copepod poop is an important part of the biological pump. In other words, these animals’ poop transports atmospheric carbon dioxide (which is trapped in organic matter, or fixed carbon) to the seafloor, where it is stored in seafloor sediments.  The poop also provides important nutrients to other animals that live within or on top of these sediments. Copepods have been shown to ingest microplastics in the wild. The ingestion of microplastics by copepods may alter the way in which these animals select their food. And of course, if microplastics are being ingested, they are also being exported to the seafloor in fecal pellets. This study was designed to look at how microplastics alter how copepods choose their food and how the ingested plastic materials affect the sinking rate of copepod poop.

Methods: In this study, the scientists grew three species of microalgae (all that copepods like to feast on) in the lab and spiked it with different types of microplastics. The microplastics included things such as nylon, which is commonly found in clothing, especially active wear, and polyethylene, which is the most commonly-used plastic in the world (it is used to make shopping bags, shampoo bottles, and toys, to name a few uses).

The microalgae with microplastics was then fed to the copepods back in the lab, where the amount of microplastics ingested. The fecal pellets from the copepods were then collected and rinsed over a screen. To determine if microplastics contained in the poop affected the sinking rate of the pellets, the scientists dropped the pellets into cylinders filled with filtered seawater. They marked where the pellet was in the cylinder every 40 mm. To determine how different each pellet sank with microplastics, the scientists also measured the rate at which copepod poop without microplastics fell through the water column. When the poop reached the bottom of the cylinders, they were taken out and examined under a microscope. This way, the scientists could count the number of plastic pieces in each pellet.

Results: The scientists found that copepods preferentially liked to eat microplastics in a smaller size range (10-20 um), with a preference for the polyethylene over nylon fibers. When the copepods were exposed to microplastics, they preferentially did not eat as much algae. In addition, the copepods shifted their preference for one species of algae over others. Nylon fibers impeded ingestion of algae that was a similar size and shape to the microplastics. The scientists think the copepods associated algae of similar size and shape with microplastics, and thus avoided eating that algae species in an attempt to avoid plastic consumption.

The study confirmed that fecal pellets that contained both polyethylene and nylon particles were slower to sink through the water column. There was a difference in sinking rates between poop that contained more polyethylene, a denser microplastic, compared to nylon, a less dense material.

Why is this study important? This study is one of several that highlight the ways in which plastics are negatively affecting our food chain in the marine realm. The reduced sinking rate of fecal pellets may also affect the rate at which carbon dioxde, a major greenhouse gas, can be removed from the atmosphere through photosynthesizing algae who are then eaten by zooplankton. If fecal pellets are left to float for longer, there is also a higher potential of the microplastics being re-ingested by other zooplankton through coprophagy (ingestion of fecal pellets). On long and short timescales, the decreased export of poop and fixed carbon dioxide to the seafloor may have large consequences, as plastic within poop could keep more carbon from being exported and stored on the seafloor.

Plankton Photo Shoot Part II: Creating the Perfect Image

Adriane here-

This post is a follow-up to one I wrote previously called ‘Plankton Photo Shoot‘. In that post, I described how I take images of my fossil plankton using a scanning electron microscope, or SEM. But that was really just the first phase of taking images. In this post, I’ll talk a bit about what I do with the SEM images once I have them, and how I clean them up.

After I have SEM images, I save them to a few different folders. When taking images of fossil plankton, we usually take several pictures of the same specimen: one of the spiral side, the umbilical side (think of this as your back and front), and one of the side view of the specimen. After the images are organized into the appropriate folder that corresponds to the side of the plankton I took an image of, I then begin the editing process!

This is a screenshot of an image of a plankton species called Globorotalia tumida. Here, the image is imported into Adobe Photoshop.

The first thing I do is open the image I want to work with in Adobe Photoshop. Once imported, I then use the ‘Quick Selection’ tool to draw an outline around the fossil. I do this so I can copy and past just the image of the fossil into a new document and cut out the background. One I have the fossil isolated, then the real fun begins!

This is another screenshot of the fossil isolated from the background using the ‘Quick Selection’ tool in Photoshop.

The first thing I do with an isolated fossil image is to zoom into the image. The reason I do this is because I want to inspect the image to see how well the ‘Quick Selection’ tool worked. Sometimes, if an image does not have a lot of contrast, or the background looks the same color as the fossil, some of the background will be included in the selection. If this happens, I then use the Eraser tool to go around the outside edges of the image. This makes the image more crisp and defined!

This is what the fossil image looks like when I zoom into the image at 400x magnification. The edges already look quite good, but notice there is a small gray ‘halo’ around the image, which is especially apparent on the left side.

This is what the image looks like after using the eraser tool on the edges of the image. You can’t tell too much, if any, of a difference, but it does help give the image a bit more definition! I also delete the white background before I save the image as a .PNG file type (.PNG files don’t have a background, which is great because then I can put the image against any color background I want to later).

The final image! From here, the image is saved as a .PNG file for later use!

And that’s it! I now have a beautiful fossil image that will be used later in a publication! Of course I have to repeat this process for each fossil (which, right now, I have over 200 to edit!). Stay tuned for Part III of Plankton Photo Shoot, where I’ll show you how these images will be displayed in a publication for other scientists!

Johanna M. Resig Fellowship: Honoring a Wonderful Foraminiferal Researcher

Adriane here-

I’ve done a lot of stuff during my time here at UMass Amherst, probably too much stuff (including building this website with Jen and collaborators, which is definitely something I have no regrets about!). Because of the amount of teaching, outreach, and large research projects I’ve done and continue to do, my PhD, which is funded by my department for 4 years, will take an extra year. However, my funding runs out at the beginning of May 2019.

It’s not uncommon for a PhD degree to run over the 4 year mark; in fact, it’s really quite common. But how to sustain oneself for this extra time is the tricky part. There is money available to graduate students to support us in our final year(s) of our degree through fellowships and grants. These are often very competitive and hard to win, but totally worth applying for. So I decided to apply for a fellowship to fund the remainder of my time here at UMass.

The fellowship that I applied for is through the Cushman Foundation for Foraminiferal Research, an organization specifically for scientists who work with fossil plankton. The organization has been around for quite a while, and its members include professors, researchers, and students from all over the world. The Foundation is great because they have several grants and awards for students, to fund their research and travel to local, regional, and international meetings.

The Johanna M. Resig Foraminiferal Research Fellowship is named after its namesake, who was a life-long foraminiferal researcher and editor of one of the most prominent journals for foraminiferal research, the aptly-named Journal of Foraminiferal Research. Johanna was born in Los Angeles, California on May 27, 1932. She  found her love for geology at the University of Southern California, where she received her Bachelor of Science in 1954 and her Master of Science in 1956. After graduation, Johanna went to work for the Allen Hancock Foundation. There, she studied foraminifera that live off the southern coast of California. In 1962, Johanna was awarded a Fullbright grant, a very prestigious award that gives money to scholars to study abroad for a few years. With this grant, Johanna continued her research at the Christian Albrechts University in Kiel, Germany. While in Germany, she earned her PhD in natural science in 1965. Once she had her doctorate, Dr. Resig began a professorship at the University of Hawai’i as a micropaleontologist in the Institute of Geophysics. She was the first woman recruited in the Hawai’i Institute of Geophysics, and remained the only one for several years. She was a professor at the university for over 40 years, where she published over 50 articles and book chapters on foraminifera. Dr. Resig published mainly on benthic foraminifera (those that live on the seafloor) as well as planktic foraminifera (those that float in the upper water column). She worked with sediments from all over the world, and also used the shells of foraminifera to construct geochemical records of our oceans. During her career, Dr. Resig described and named five new species of foraminifera and even a new Order! Dr. Resig was not only known for her research, but she was also a dedicated mentor and teacher at the University of Hawai’i. While there, she taught hundreds of undergraduate and graduate students in her courses, and mentored about a dozen graduate students. When Dr. Resig passed away on September 19, 2007, her family gave funds to the Cushman Foundation in her name, and thus the Johanna M. Resig Foraminiferal Research Fellowship was established.

Interestingly, my PhD advisor, Mark,  worked with Dr. Resig during her career. They sailed together on a large drillship called the Glomar Challenger, which took sediment cores of the seafloor for scientists to study. During an expedition together to the western equatorial Pacific (called ‘Leg 130’), they were both micropaleontologists (scientists who use tiny fossils to interpret the age of the sediments and reconstruct the ancient ocean environments). Mark is a huge fan of country music, and he recalled that he loved to play country music on the ship while the scientists were working. One song he was particularly fond of, ‘All My Exes Live in Texas’ by George Strait, was deemed entirely comical by Johanna! Mark describes Johanna as a dedicated scientists, a wonderful micropaleontologist, and someone that was a joy to be around.

The fellowship named after Dr. Resig will support the remainder of my time as a PhD student at University of Massachusetts Amherst. The money will be used as stipend (which is a fancy academic word for income), but it can also be used for analyses and lab expenses and travel to conferences. One way in which I’ll use the money is to pay an undergraduate student to process sediment samples that I will use in my next research project. This way, I’ll get a jump-start on my next project, and a student will be earning money doing science. They will also learn more about the samples that are collected as part of scientific ocean drilling. It’s totally a win-win situation, and I feel that by using part of the fellowship to mentor and help the next generation of students, I am honoring Dr. Resig’s memory and her commitment to mentoring and advising.
