If you’ve been following Time Scavengers, you may have seen the paleo news posts that my students have written, which have been great! This post is a summary post about what I learned and what my students learned throughout the course of this project. I teach an upper- level class for geoscience majors at The University of South Florida called paleontology and stratigraphy. When I was designing what the course would look like, I tried to think about the skills I most wanted my students to have upon leaving. As most of my students in my classes won’t become paleontologists— they’ll go into a wide variety of science jobs— I wanted to find skills that will help them, no matter where they go. A lot of the things I want them to learn are already skills emphasized in a lot of college classes, including the ones I teach— critical thinking, evidence- based arguments, hypothesis testing, and other things. But one thing that I value a lot in science is the ability to communicate clearly with anyone, not just scientists.
The talks, seminars, and papers that I see and read and resonate with most are those that are easily accessible. It’s hard to get engaged and get excited about a topic (even something in my field!) if I have to continuously stop and think about what the person might be trying to say— I think most people would probably feel the same. I wanted my students to practice explaining scientific concepts in a way that anyone who wanted to read it would understand, so that when they wrote papers, presented research talks, talked to future clients, or even chatted with people about their science in cabs or at family gatherings, they could remember how to break down complicated concepts in an effective way without removing the main points of the science.
Students chose a recently published paper of their own interest and wrote a draft of their summary. Then, they had a chance to learn a bit more about the peer review process scientists go through (check out more on how peer review and publishing works here) by trading drafts with a partner and reviewing their work for clarity, accuracy, and grammar. I made final suggestions as the editor. Finally, the posts were published on this site! You can read all of my excellent students’ work here: USF Paleo/Strat
Students really seemed to enjoy this project, so much so that I had an idea for this spring and summer: to get students involved in a long term project to develop their scientific communication skills. Over the next few months, you’ll start seeing posts from my students who are writing a series of blogs and paper summaries as they work to develop their scientific communication skills. If you haven’t yet had a chance to meet Kailey, Lisette, Baron, or Mckenna, check out their bios now!
Entering the academic world and starting graduate school often means moving away from your family and loved ones and starting a new adventure. Each program, position, or job often comes with an associated move. We hope to share our successes and failures navigating moves and the burdens that come with them.
Jen [Illinois > Ohio > Tennessee > Florida > Michigan]
I have had four major moves (to new states) and three minor moves (local moves). Each move presented different challenges and experiences. My first move was from my home in Illinois to Ohio University to start my MS. This was about 6 hours from my mom’s house and we simply packed her Highlander and that was it. I had found a furnished (shared) apartment so I didn’t need any furniture and was able to fit everything else into her vehicle. I did not have a car of my own at this time and she drove home the following day after helping me unload the vehicle.
I did another move within Athens on my own to an unfurnished (shared) apartment. I took a few trips to bring a futon mattress but didn’t really have any other furniture items. A hiccup – probably an issue with most college towns – is that lease signing happens so early! So I had about a 1 month gap between leases and it just so happened I would be at field camp. So I moved all of my apartment into the lab for storage (thanks, Hannah and Alycia!) and then when I returned I moved into my new apartment. At this stage, I was borrowing my mom’s highlander and did the move(s) on my own. I had a small foldable dolly that I had gotten for ~20 bucks at Ace Hardware. Both of these moves were very inexpensive since I had essentially no furniture. I slept on a futon mattress on the floor of my second Athens apartment.
My move to Knoxville, Tennessee took more planning and was more costly. I was able to fill the Highlander (thanks mom!) with most of my belongings from Athens but I had obtained a futon mattress and a few extras like lamps and storage containers. Not everything fit into the Highlander, but Jeb (my partner) was willing to drive down separately with me and was able to fit the rest into his sedan. After we got situated in Knoxville, Jeb went back to Athens and I drove up to Chicago to get some furniture from my mom’s house since I now had an apartment but no furniture. My mom and I rented a cargo van from Enterprise and I drove the van and she drove the Highlander back down to Tennessee. We had the van for about a week so I could also buy a bed and bed frame (woo adult life) and then Nancy (mom) drove it back to Chicago. This totalled ~$700 for gas and van rental for the week. There are certainly cheaper ways to do this but this is what worked out for us at the time. After two years in the apartment, Jeb and I decided to move into a house in Knoxville. We found this house on Craigslist and for the in-town move, his mom drove up with their truck and helped us move everything.
The next move was to Gainesville, Florida where I got a postdoc at the Florida Museum of Natural History. I also was accepted to participate in a month-long workshop just before the postdoc was set to begin. So Jeb and I moved a trailer full of our stuff to Gainesville when he dropped me off at the workshop (a ~8.5 hour drive but ~10 in with the trailer). Our Subaru’s battery died on the way down, which was a difficult adventure (thank you nice Georgia man). We then stayed around looking at some local apartments. I eventually got an email from a current grad student there with an available house for very cheap – rented out by old staff and faculty of UF. The house was about 10 miles outside of town (a bit of a hike on my bike) but we couldn’t beat the rental price. The day my workshop was ending, Jeb drove down another trailer and our cats to the house. He had to pack it on his own and it was difficult. He arrived ~2:30 am and we had to start unpacking because we needed an empty trailer to pick up our stored belongings the following morning. This can be summed up by Jeb saying: ‘watch out there’s a bag of knives in the back’. The 6×12 trailers were ~$50 for a few days so we did that for two trips. We used Uhaul for both the trailers and storage – when you rent from them you can get a month of free storage!!! Take advantage of this program!!
Now that I had made it all the way south, it was time to head back to the midwest. We moved to Ann Arbor, Michigan from Gainesville at the end of August 2019. This time we rented a 20 foot U Haul truck with a trailer to pull the Subaru. We got the U Haul 3 days in advance to pack it best we could – yes this was more money but we desperately needed the time to get everything situated. We drove 14 hours the first day with two cats in the cab of the truck and spent the night at a Super 8 that we had selected for the giant parking lot… that was full when we arrived at 11:30 pm. The hotel was a complete crap hole and we slept and got up and drove another 7 hours to Ann Arbor. This one I budgeted out and recorded all of the expenses. Here is the breakdown: U Haul = $1110.56; Gas = $229.85; Food = $14.82; Hotel = $55.05 for a total of $1520.28. We obviously didn’t eat a lot and were very exhausted when we got up to Ann Arbor. Most recently, we did a more local move from Ann Arbor to Chelsea, about 20 minutes west of Ann Arbor. This was unfortunately during the stay at home order. We were able to rent an in town U Haul for about 24 hours. For whatever reason we went with the 10 foot truck, which required three roundtrips and several in our Subaru as well. We did all the packing and unpacking on our own, washed our hands a lot and did our best to be socially distant during the move. The truck cost $136.61 and gas was ~$16 for a total of $152.61.
Other things to consider: deposits, some companies require first and last month rent, changing electrical can have a processing fee, setting up internet services has a fee, cleaning supplies, don’t forget a new shower curtain (we did multiple times).
Sarah [North Carolina > Alabama > Tennessee > Florida]
Moving regularly can really have a big impact on you, especially since it’s easy to feel isolated in academia and it’s expensive (especially on a graduate student budget!). Jen covered a lot of the details I would have, with moving truck logistics and costs, so I’ll try and focus on other aspects of moving to consider!
With each of my major moves to new states, I did so as cheaply as possible, since I was a graduate student/recently graduated graduate student for all of them. I did so by moving in a cargo van or the smallest possible moving truck. This was made easier by not taking a lot of furniture with me when I moved. I went to thrift stores the week I moved to town and purchased things like tables, chairs, bookshelves, etc for cheap and sold them what I could or donated them when I moved again. Usually, I could afford to get all the furniture I needed for under $100-$150, which was way easier and cheaper than it’d be to rent a bigger truck to haul it hours away.
The major concern when I move is my pets- if you didn’t know, I have a LOT of pets. My partner and I have fostered for a few different animal shelters and we have quite a few of our own and some fosters that ended up just staying with us permanently. So moving can quickly become a hassle, so I’ll give you a breakdown of the things you might need to think about! I’ve never flown with my pet (I have too many and I have pets that most airlines don’t generally allow on board), so I can’t give you advice on that! I always drive with mine! Here’s a picture of all of my critters that I’ve moved with!
Do you have pets that could be not allowed in a rental agreement? I have a pitbull- mix, which can often be discriminated against in rental houses and apartment complexes. While I don’t agree with these policies, I can’t do much to change them. When moving to Tampa, I spent a lot of time trying to find apartments that did not discriminate and I did eventually find a good one. We contacted a real estate office that helped with apartment rentals and they gave us a list of apartments that didn’t have restrictions. A lot of apartments will also discriminate against “exotic pets” (i.e., anything outside of a cat or dog).
My best advice in this situation is to call and talk to them before you move in. I called a number of apartments and talked to them about my bunnies (I have two-Leo and Josie, 8.5 year old siblings). Most of the apartments were willing to waive that restriction when I explained that my bunnies were litter trained. I was also able to get the pitbull restriction waived when I was in town and made appointments to meet the apartment managers. Piper won them over in a minute with her endless affection!
Do you have more pets than a rental agreement usually allows? This can be a tough one! Again, if you feel comfortable, just call your apartment. I called in advance and explained that while we had two dogs, we also had two small bunnies and a guinea pig, all of whom were litter trained or lived in a hutch and wouldn’t have access to the rest of the apartment. My new apartment said that was fine, while others said no (so I didn’t rent from them).
Do you have money for pet deposits and monthly pet fees? Many places charge pet deposits that can be hundreds of dollars and monthly additions to rent. Make sure you can afford those charges before the move.
Look for vets BEFORE you move! If you can, make sure to find a vet that you think you’ll like before you move. This is *especially important* if you have a pet that isn’t a cat or dog, since not all vets are required to treat critters like bunnies, guinea pigs. This is so important because you never know when an emergency will happen! One of my bunnies had an emergency medical situation when we first moved here, and I had luckily already scoped out an emergency vet that could see bunnies. Call the vet office before hand to make sure they’re accredited (i.e., the AAHA- the American Animal Hospital Association) and to make sure they have someone who can provide help with your pets’ specific conditions, if they have any. It can be really scary not to have a vet identified in an emergency! Tip: does your local university have a vet school? They may have a clinic you can use!
Have at least a month of supplies stored, just in case. This is super important because critters don’t always tolerate change well! Make sure to have enough food, litter, and other needed supplies so that you can keep their lives a bit steadier while you move to a new place. Sometimes, you may need to take a few days to figure out where to get supplies in your new town (or, like in my case, 2017 Hurricane Irma came just a few weeks after we moved to Florida and we needed to have a bit extra on hand!)
Make sure to be extra patient with your pet. Moving is tough and it’s a lot harder when you don’t know what’s going on. Make sure to praise your pet, give them extra attention and treats. Consider giving them a new, special toy to distract them. Be patient if they forget their manners and use the bathroom inside- sometimes, stress can make your pets react weirdly. With my dogs, we had to move them to a separate room when we were loading the truck so they didn’t see it, which kept them calmer. If you know your pet is nervous, ask your vet if there’s a good medication option to help them get through the car ride.
Adriane[Virginia > Ohio > Virginia >Massachusetts > New York]
Jen and Sarah have already given you great advice above related to pets and moving fees, so I’ll keep this brief and provide some additional advice. First of all, I hate moving. My family moved a lot when I was younger, and as a consequence I feel like I don’t really have a ‘family home’ when I think back to my childhood. So when I move, the feelings of anxiety and unsteady home life come flooding back. Here, I’ll give you some insight into how I deal with moving.
When I moved to Massachusetts, it was just my husband and I. We had rented a U-Haul truck with a car trailer. My husband drove the truck towing his car, and I drove our Jeep with our two cats crated in the back. We did the drive from Virginia to Massachusetts in one day; it took 14 hours and it was HELL. We were all tired, but luckily our hotel in MA was nice. I had researched hotels near our new apartment extensively, as I knew we needed one with a large parking lot, a free breakfast (that’s always my requirement for a hotel; if I’m paying to stay with you, feed me), and of course they had to be pet friendly. We stayed at a Howard Johnson with two queen beds, which I hoped the cats slept on their own bed. No, they slept with us (ok, it *was* super cute). The next day, we drove to our new apartment and moved in. We had trouble moving in our couch (our apartment was on the third floor, with a narrow stairwell), but lucky for us a neighbor helped (we became and still are to this day good friends).
I really came to love our Massachusetts apartment, which really became our community and home. Therefore, when I got the postdoc offer from Binghamton University in New York, my excitement soon turned to anxiety when I realized this would require another move. However, in my offer package, the university would cover moving costs up to $3,000. I took full advantage of this. I hired a moving company for our moving day, and we were able to move 3.5 hours away from Amherst, MA to Binghamton, NY in one day. Whew! The cost came to a bit over $2,900 but under $3,000. If I can help it, I will never move again without hiring movers. Just be aware, with moving reimbursements from universities, especially public universities, the state may require an invoice or bill of lading. I did not realize this when I moved, my moving company has been unresponsive when I try to get in touch with them, and therefore I’m still waiting for my moving reimbursement from New York state today.
As mentioned, I become super stressed when I move. Here’s some things I did before our move to NY from MA that helped with the stress:
I tried to pack a box or two every day for a month before we moved. This allowed me to organize stuff and carefully pack all my valuable things (read: fossils).
I carefully labeled boxes with their contents, and grouped boxes with similar contents together. This way, when we moved, the movers kept together all the kitchen stuff, office boxes, etc. It made unpacking easier as well.
I Googled Binghamton (where we were moving to) and made a mental list of things I wanted to try, do, and places to visit when we got there. I find that if I have something positive and fun to look forward to, this reduces my anxiety greatly. I also feel more comfortable visiting or moving to a place the more I know about it beforehand.
I visited my favorite shops and stores in Amherst, and brought those foods, wine, and beer with us to our new home. It was nice to have these things with us in New York, as they were small comforts and gave us, oddly, a sense of peace.
I talked about my anxieties about my moving anxieties with my husband, and cried a lot. I have a thing where I stop talking about things that bother me, which will just increases my anxiety about an issue and causes me to cut myself off from those around me. It’s super unhealthy, I know, but I made a conscious effort to reach out and share my fears with my partner about moving. This helped my mood immensely, although it didn’t totally dissipate the anxiety. If you are like me, I would also strongly suggest visiting a therapist to share and work through anxieties about moving (I probably should have).
Recently, I went to the Washington D.C. area to visit the Smithsonian Museum of Natural History (which you can read about here) and to attend a workshop on best practices for new faculty members. But while I was there, I spied some excellent geology right in the city! I already showed you some of those while I was in the museum itself, so I’ll show you some of the other amazing pieces of Earth history that I saw!
I want to remind you that looking at amazing geology doesn’t have to wait for you to be on vacation or in a faraway destination-you can see these sites anywhere, if you’re paying attention! If you want to read more of these types of posts, check out my post from last year on the geology of bathrooms.
This first image is of a beautiful stylolite in a marble countertop in the bathroom of a café in the center of Washington D.C. A stylolite is caused when rock, most commonly carbonate rocks like limestone (which we call marble when they are metamorphosed), are put under extreme pressure and the individual grains will compress and leak fluid, leaving behind a squiggly line, like what you see in image 1. Just beautiful!
Our next stop brings us to Union Station in Washington D.C., where I found this magnificent staircase completely by accident (image 2). I was visiting Gallaudet University and the first signing Starbucks, when I got turned around and ended up at a different Metro station than I had originally intended. Well, serendipitously, I found this absolute beauty, making the detour more than worth it. This rock, just like the image before, is a type of marble, though it has very different colors. The red color in this marble can be attributed to chemical impurities- red is typically what we’d see if iron and feldspar was present in the marble sample. You can also see veins filled with calcite and look like quartz all throughout the staircase! I was intrigued about where this marble came from, so I did a little research. There wasn’t a lot of information, but it seems that this marble likely came from Vermont (See this blog here: https://blogs.agu.org/magmacumlaude/2014/06/13/building-dc-union-station-just-the-floors/), which was created over 400 million years ago, when limestone produced from a shallow sea collided with a volcanic arc and metamorphosed in an orogeny, or a tectonic collision. This is a fairly common scenario with how we get a lot of our marble from the Paleozoic in North America.
Our tour continues to just outside of Washington D.C., to Arlington, VA, where I was visiting a friend in the area. As we were walking to breakfast, I was treated to a spectacular number of rocks featured in the buildings’ walls along the way. First, is a beautiful granite (image 3). The pink mineral is potassium feldspar (K-spar, for short), intermixed with the milky white mineral (quartz) and a lot of amphibole, the black colored mineral that’s heavily present on the left side of the block. Granite also usually contains biotite, a black mica. If you take a look at this granite, you’ll see that the individual crystals are quite large, which tells us a lot about its formation. It’s telling us that it was formed intrusively; meaning, it was formed in an area not exposed to Earth’s surface and it cooled slowly, giving the crystals time to grow. I stopped to take a photo of this because the amphibole (there are many varieties of amphibole-hornblende is the most common in granite) because the heavy presence of the swirling amphibole isn’t something I usually see in most granite samples. Second, I saw these gorgeous phyllite samples on the outer wall of a building (image 4). Phyllite is a low-grade metamorphic rock, which means it’s not exposed to extremely high amounts of heat and pressure, but it has undergone significant changes from its protolith (otherwise known as its parent rock). In the case of phyllite, its protolith was a shale (compacted mud). You can recognize phyllite by a few different characteristics. During the metamorphic process, muscovite (a soft mineral in the mica family) develops, giving phyllite a really lovely shiny appearance (you can think of mica as being like nature’s glitter; just like glitter, mica is nearly impossible to completely get rid of if you accidentally get it everywhere!). You can also recognize phyllite by the gentle bands that form. Many metamorphic rocks are foliated, which we can think of as banding across a rock. The more pronounced the banding usually indicates a higher amount of metamorphism applied to the rock. Phyllite has subtle banding, which indicates that lower amount of metamorphism.
So, this next image (image 5) isn’t in D.C., but it was found during this trip in College Park, Maryland on the University of Maryland’s campus. It’s another gorgeous example of granite, this time in a fountain. Sometimes it can be really hard to recognize rocks when you’re used to seeing them beautifully polished and sealed (like the granite in image 3, but you can definitely do it with practice!) Just like in image 3, if you look closely at this fountain, you’ll see large crystals, because it’s an intrusive rock, and the same types of minerals- our pink K-spar, milky quartz, and black amphiboles. An intrusive magmatic event from millions of years ago had to form and cool, and then that granite had to be exhumed (brought to the surface) for someone to make that fountain. So cool!
Last, but certainly not least, let’s look at the marble here in the Ronald Reagan airport (image 6). This gorgeous marble makes up part of a seafood restaurant right near the entrance to the airport, before you go through the security line. Sorry that the image is kind of far away, but this was the closest I was able to get before having to get through the security line! One of my favorite things about marble is how different it can look from sample to sample. This marble shows completely different features than the ones I showed in images 1 and 2-remember, the color of marble is driven by chemical impurities. You can see large scale veins of what is likely calcite all over the rock itself as well as some dissolution features on the left side.
Recently, I went to the Smithsonian Museum of Natural History for a few days for some research (image 1)! This was an especially exciting trip because I got to see the BRAND-NEW Fossil Hall exhibits that the curators and staff have been working on for years (image 2)!!
My main goal for going to the collections was to make a personal database of the specimens present at the Smithsonian that belong to the groups I’m currently working on, echinoderms called Diploporita and Rhombifera and make notes of my own for future projects I’d like to start. For example, many of the specimens at the Smithsonian had unusual preservation, so I was thinking about possible projects for myself and for future research students to look into why these fossils were preserved the way that they were. I took photos of many of the specimens so that I’d have a good reference for later, too (image 3).
My main goal for writing this post, however, is to show you what it’s like to work at a museum! Museums are amazing places to go and learn and have fun, but it’s a totally different experience to go to a museum to look at its exhibits, as opposed to going to look at the collections. The exhibits at the Smithsonian, the halls filled to the brim with amazing rocks, fossils, and artifacts, only make up a teeny tiny percentage of what’s actually stored in the museum. So, without further ago, here’s the behind the scenes tour!
So, while the exhibits are absolutely beautiful and show off magnificent tales of Earth’s history, the collections areas show off something completely different but equally beautiful: the rows and rows of cabinets that are chock full of fossils just waiting to be studied (Image 4)! Every time a scientist publishes a paper on a fossil, that fossil has to be put in a public museum so that it can be studied by other people in the future (this isn’t always true, but almost all journals require that you put your fossils in a public museum). Some of the fossils in those collection rooms are absolutely beautiful and totally worthy of being put in an exhibit (image 5), but so many more, while they aren’t as “perfect”, give us insight into scientifically interesting questions.
Now, I want to show you a little bit about the Smithsonian’s exhibits! I want to show you my favorite new exhibit. You guessed it-it’s about echinoderms! This new exhibit shows the changing body types we see in these fossils throughout geologic time (image 6). They also did some really great work on an Ice Age exhibit and the megafauna that lived there (like mammoths, the Irish Elk, large sloths). It was tied in really well with learning about how climate change has affected life on Earth in the past and life on Earth now!
Finally, I want to show you around the exhibits you might not have noticed at the Smithsonian- the floors and bathroom counters! Since this is the nation’s most famous natural history museum, you know they have to have some good geology in their building materials! The main staircases that run through the museum are marble (metamorphosed (meaning, it was put under a lot of heat and pressure) limestone). Marble often leaves us clues about how it was metamorphosed by leaving behind stylolites. Stylolites are deformation features-meaning, the marks that rocks leave behind when they’re being squished by geologic processes. They often look like little squiggly lines! Check out the epic stylolites in the marble staircases of the Smithsonian (image 8)! Finally, here is a column that is made out of a rock called a metaconglomerate, which is a metamorphosed conglomerate (image 9). To put that into normal words, a conglomerate is a sedimentary rock that’s made up of large pieces of material (like pebbles or larger) all jumbled together. A metaconglomerate is simply one that has been deformed from heat and pressure! You can tell that this column been metamorphosed by how the large pieces of rock look like they’ve been stretched out and bent in weird directions.
It’s hard to believe, but the holiday season is fast upon us! I know you’re probably already thinking of all the things you want to do to prepare- decorate your home, inside and out, send holiday cards, buy presents, bake delicious cookies, etc. This post today is about ways we can all take to make sure that our holiday celebrations are more eco-friendly!
One thing to notice is that thrift stores are FULL of great holiday decorations! Why buy new when you can get awesome decorations for a fraction of the cost? Just this weekend, I was in a thrift store looking for a nightstand, when I came across a ton of great holiday decorations. I walked away with enough outdoor string lights to decorate the trees in my yard for a total of $4, all working and in great condition. There were artificial Christmas trees there, Hanukkah decorations, and more- all for a low price. Consider buying used to keep these types of things out of the landfill. Try to stay away from balloons, plastic streamers, plastic confetti, and decorative grass (like the kind you find in Easter baskets a lot of the times)- these are not recyclable and there are paper alternatives for many of them! As for balloons, many of the times, their pieces get stuck outside and animals try to eat them- causing illness and even death.
As so much of this is made out of plastic, decorations will absolutely last in a landfill for years to come. Reduce the amount we all collectively purchase from stores, save yourself some money, and reduce the landfill- it’s a win- win- win!
Ugly Sweater Parties and Holiday outfits
Skip Target and Walmart and go straight to the thrift store. So many people buy Ugly Sweaters, wear them once, and then donate them! I am not advocating for people to go to thrift stores and buy perfectly good, used clothing that’s cheap as a practical joke (many people use thrift stores as their primary clothing source- and for good reason! It’s accessible to a range of budgets) store, but there are *plenty* of Christmas themed sweaters at the thrift store that were made for the purpose of wearing to holiday parties! The clothing industry is responsible for an extreme amount of landfill waste and microplastic pollution in the ocean. Holiday sweaters often have glitter, sequins, and other items on it that definitely contribute to that- buy used!
There are also so many kids’ outfits in brand new condition at the thrift stores, as well as holiday party outfits for any age! Go there before going to a store to buy a new outfit!
Cards and wrapping paper
I love sending holiday cards and getting them. But there are ways we can send and receive holiday cards with a bit more thought to the environment.
First, and easiest, make sure to recycle the holiday cards/envelopes you choose not to keep! Second, try to select cards and envelopes that are devoid of glitter and anything that isn’t strictly paper- it cannot be recycled as well. Make sure that the cards and envelopes you’re disposing are recyclable, as well.
As for wrapping paper, don’t buy wrapping paper with any metallic foils or glitter- they aren’t recyclable. Skip the ribbons and bows- you can get some great all paper options that look great but can be recycled! One fun thing you can do is use paper you already have to wrap your gifts. It might not be holiday-themed, but it can reduce your waste output (I’m actually using the wrapping from my toilet paper rolls! I use a company (https://us.whogivesacrap.org – the toilet paper is made from recycled paper, so no more trees*!) and their rolls are wrapped in cute paper (no plastic at all!) My partner and I decided the paper was too cute to throw away, so we’re wrapping gifts in them.
This is a big conversation. Simply put, we have to do something to reduce our constant purchasing of new things that will eventually end up in a landfill. That doesn’t mean we have to change our gift-giving traditions, but there are ways of gift-giving without the carbon footprint.
Appliances. How many of us are looking at new tablets, phones, robot vacuums, or instant pots this holiday season? So many of the Black Friday sales are dedicated to these types of gifts right now.
First, we really need to consider holding on to our phones and tablets and other devices for as long as possible- these things use Rare Earth materials that, as you might have guessed, are rare- we can only mine them for so much longer. So consider holding on to your current devices until you absolutely need to get a new one.
If you really want a new kitchen appliance, try going on Craigslist or Facebook Marketplace! For example, my partner has really been wanting to try out an instant pot, but neither of us were willing to buy one. In our area, people are listing their used instant pots that they used once or twice and decided they didn’t want them! Try buying a gently used one for a holiday gift- it saves a ton of money and you’re reducing your carbon footprint by not buying a new appliance.
There are SO many things you can buy used or refurbished- just try! Books, furniture, appliances, children’s toys, and more can very often be found almost brand new for so much less. Before buying something new, see if you can find it used, instead! Last week when I was thrift store shopping, the section of children’s toys was huge! All of the toys looked to be in great condition- for those of you shopping for kids out there, see if you can’t give a toy a second home. Often, that toy only needs a little TLC to make it as good as new (seriously- I think the entire stock of Paw Patrol toys was there!).
Experiences. This holiday season, consider giving the gift of something to do. How about buy a loved one a zoo or aquarium membership, tickets to see the latest movie, a gift certificate for a massage, or a chance to go to a museum they’ve always wanted to see? Gifts like this, that can be shared together, can make wonderful memories that won’t contribute nearly as much to a landfill. I don’t know about you, but I cherish the time spent with family much more so than any gift.
Practical gifts. We can also consider giving someone practical gifts! I know this might sound weird, but my mom’s annual holiday gift to me while I was in graduate school was paying for my bunny’s annual checkup at the vet office. It was a gift of love, for sure, and made me smile because it was something I really needed. Consider giving the loved ones in your life things that they could use- maybe a pack of silicone, plastic free sponges? A set of plastic free freezer bags? Maybe take your friend who’s in grad school grocery shopping? There are all kinds of great gifts that will be useful and not get discarded are great!
Holiday Baking. Really, my favorite part of the holiday- cookies and cakes! Consider not using plastic wrap to wrap your goodies, if you can help it. Wrap them in paper, or beeswax, or go to the thrift store and pick up a dozen of those holiday themed tins (seriously- there are so many there!) Consider that the wrapping will often be discarded, so try to move away from stuff that can’t be recycled or will end up in the landfill. Also, baking is a great gift if you want to move away from giving someone an item that might not be used or might end up in a landfill! Do you have a killer banana bread recipe? Do you love making cute iced cookies? Make someone’s day and bring them some!
I hope all of you reading this have a holiday season filled with joy, time with loved ones, and relaxation. If we all make a few small changes to how we approach the holiday season, we can all reduce our carbon impact! Happy holidays, everyone!

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.
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!
Photo: 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 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.
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.
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 🙂
“Do you have vacation for three months?” “Do you even work when classes aren’t in session?” These questions get asked an awful lot to people who are in academia.
Sometimes, it can seem like that! Academia, for all of its unusualness, is a great place to work if you value schedule flexibility, especially when classes aren’t in session. As a matter of fact, as I type this on a Tuesday morning, I’m working from home in my pajamas!
There is a misconception that a professor’s job ends when the semester ends-this couldn’t be further from the truth! So, what do we do during the summer? It varies, depending on our specific positions, but my experience so far has been from someone with a high teaching load (3 lecture courses/semester)
Catch up on scientific literature! During the semester, it can be hard to block off time to read new scientific papers to see what new ideas have been published and to develop ideas on my research further.
Update lectures for next semester! Science changes quickly-this means that professors have to continuously update material to teach students. This summer, I’ll be updating material from my lectures that reflects new understanding of different topics. For example, new research about dinosaur evolutionary relationships that has been published in the past year or two means I need to update my slides on that material!
I also take time during the summer to edit assignments, exams, and lecture material that didn’t quite work the way I wanted it to. I take notes during the semester of the parts of lectures that weren’t engaging enough, or exam questions that may not have been entirely clear. This way, I can be much more prepared for the classes I teach every semester! Many professors also develop new courses during the summer, if they’ll be teaching new courses.
Catch up on service projects! This depends very much from person to person, but academic service is a big part of our jobs that often goes unseen by the public. Many of us serve on committees for professional organizations (e.g., The Paleontological Society). I serve on a grant committee that does the bulk of the work in early summer each year, so I spend a week or so reading grant proposals for researchers undertaking new paleontological research.
Conduct research and field work! During the summer, I have a lot of unscheduled time, which means I can take trips to museums or out to the field without too many scheduling difficulties. Some academics take their entire summer to travel, others only a little bit of time. It really depends. This summer, I won’t be traveling too much-probably only one or two short trips to collect data.
Write papers and grant proposals! The summer is a great time to write and submit papers, as well as grant proposals, both of which are required of a lot of academics. It’s easier to block off time to write when classes aren’t in session. During the summer, I like to write in different places than I do during the semester-instead of my office, I’ll write in coffee shops or at my house for a change of scenery.
Catch up on training! This summer, I’m taking a four-part course through the university to learn how to become a better ally for my LGBTQ+ students, as well as a course in learning how to be an ally for undocumented students. Personally, I like being able to do this during the summer so I have more free time to reflect on what I have learned and think about how to incorporate what I have learned in my classes for the upcoming semester.
Take a break! My schedule during the semester is often jam packed with classes, student appointments, and more. During the summer, I take a little more time to catch up on “life”- go to dentist appointments, run errands, and take some more time to play with my dogs and enjoy my hobbies.
This list is by no means complete, I’m sure, but hopefully you can get a sense as to what academics work on when they aren’t teaching classes! Hope all of you academics out there are having a productive and relaxing summer!
A new stemmed echinoderm from the Furongian of China and the origin of Glyptocystitida (Blastozoa, Echinodermata) S. Zamora, C.D. Sumrall, X-J. Zhu, and B. Lefebvre Summarized by Time Scavengers contributor, Sarah Sheffield
What data were used? A single, beautifully preserved echinoderm (relatives of sea stars and sea urchins) fossil from South China, named Sanducystis sinensis. Rhombiferans are extinct types of echinoderms with diamond shaped plates.
Methods: The new rhombiferan fossil was examined for all preserved features on its body; these features were ‘coded’ as characters for an evolutionary analysis. An example of a character: Does this have a stem? Yes=0; No=1. These characters were also used to code multiple other species of rhombiferan echinoderms. The reason for this was to figure out to what Sanducystis sinensis was most closely related. Computer programs, like PAUP*, take all of the characters coded and determine evolutionary relationships, based on the shared similarities between the species used in the analysis.
Results:Sanducystis sinensis falls within a large group of rhombiferan echinoderms called “Glyptocystitida” (similar to how humans are a large group of mammals). It’s an important find, as its place within the evolutionary tree of life is representative of a type of transitional fossil between a group of early rhombiferans that lack specialized breathing apparati and a group of more advanced, or derived, rhombiferans.
Why is this study important? This study paints a more complete story of how rhombiferans evolved through the Cambrian. It was not clear how the transition from rhombiferans without specialized breathing apparati gave rise to the more derived forms that we saw after the late Cambrian. This new find, Sanducystis sinensis, helps us to understand how that transition happened.
Big picture: Rocks from the late Cambrian (~500-480 million years ago) are very rare worldwide; this, of course, means that there are also very few fossils from this time as well. The late Cambrian is a very important time in Earth’s history, however, so finding fossils preserved from this time is critical towards understanding the evolution of life. Fossil finds, such as Sanducystis sinensis, have the potential to completely change what we currently know about how and when different groups of organisms on Earth evolved.
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 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.
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
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.
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.
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).
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.
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.
I recently took my geology students on a field trip to Blowing Rocks Nature Preserve on the eastern coast of Florida near Jupiter Island. This class is my upper level Sedimentary Petrology class made up of mostly geology majors (we mostly study the formation and identification of different types of sedimentary rocks, like sandstone and limestone). I wanted to show you all what we saw!
The rock that is shown here is the Anastasia Limestone, which was deposited in the late Pleistocene, which spanned about 2.5 million to 12,000 years ago. The ocean levels were much higher than they are currently, when this rock was made. We know this because the limestone that comprises the Anastasia was made underwater. Now, this limestone is exposed all along the eastern shore of Florida.
This limestone is really cool because once it was exposed, it began weathering in unique patterns. First, the energy of the waves is breaking the rocks down bit by bit. This is something we call mechanical or physical weathering. You can see evidence of this mechanical weathering by looking at how the rocks get narrower closer to the bottom-the waves usually only reach that point at high tide, so the rock above it isn’t nearly as affected (image 1). This mechanical weathering can make a few different types of features: sea arches (image 2) and sea stacks (image 2) are the kinds of things we can see here.
The cool geology doesn’t stop here though! Chemical weathering (i.e., breaking down the rock using chemicals-the most common one is water) also affects the rocks strongly here. Limestone is easily eroded away in the presence of acid, so any acidity in the ocean water or from rain above can wear away the rock in interesting patterns. Water splashes up on top of these rocks from regular wave action-that water slowly erodes the rock away, leaving small pits in the rock (image 3). However, what makes this place famous are the large pipes that are created from a mix of the chemical and mechanical weathering processes here. These pipes are quite literally large cylindrical tubes that have been worn out of the rock through hundreds of thousands of years (image 4). Water, when it comes in from waves, rushes up through these tubes and explodes out of the top! Sometimes, these can spray as high as 50 feet-hence the name of the park, Blowing Rocks (video 1)! As we go forward into the future, these pipes will continue to grow larger because they are continuously being worn down by wave energy.
There were some cool fossils on this trip, too! If you look closely, you can see lots of trace fossils from creatures who made burrows into the rock (image 5) and you can also see a lot of clam and snail fossils (mollusks!) Many of these fossils are broken up and the edges have been rounded-this is because of the higher energy waves constantly breaking them down (image 6). My students and I also found a living Portuguese man o’ war (image 7)- this isn’t a jellyfish because it isn’t a single organism, but it’s a closely related colonial organism. The man o’ war has long tentacles that can give humans very painful (but rarely fatal) stings. If you see one on the beach, don’t touch it! They are fairly common on the eastern coasts of south Florida, so be warned! All in all, my students had a great time on this trip, and they learned a lot about how rocks can change due to weathering over time. I hope you enjoyed it, too!
