This summer a few members of the UMass Micropaleo Lab traveled to Texas for the first ever International Ocean Discovery Program-Past Antarctic Ice Sheet (IODP-PAIS) Antarctic School at Texas A&M University! This program allows scientists from all over the globe who research Antarctica to come together to study the marine sediment cores stored at the IODP Core Repository. 

During our week at the repository, our mornings were filled with lectures and real-life activities led by geoscientists who have sailed on previous drilling cruises. We learned from them what shipboard life is like, how drill cores are taken, what problems can arise while drilling in Southern Ocean around Antarctica, and how to interpret the clues within the drill cores. To explore those clues, we were divided into mini-research teams and each given a core section from a prior expedition to analyze. Each afternoon we rotated among different core analysis stations: how to make and analyze microscopic smear slides, how to describe the macroscopic features of the core section, how to gather and interpret paleomagnetic and density data on the core sediment, how to scan core sections for key trace elements and improve your paleoenvironmental interpretations using element abundance data, and how to develop a timeframe for your core section (chronostratigraphy). Putting this all together, we were able to map a pattern of ice advance and retreat over where the drill core was taken. Since the core sections we were studying came from expeditions, we were able to double-check our data and interpretations against the published results and see how successful we were–my group was able to match the chronostratigraphy of the original study!

I was excited to learn so much and gain so many new friends at the Antarctic School, but my excitement was tempered by being the only woman of color in the program. I was ashamed to learn that an international program participant could not attend because they were not granted a U.S. visa in time: the American visa process is extremely biased, and as an international organization the IODP should use their agency to help all invited participants attend, regardless of their countries of origin. It is not enough to non-racist in today’s society–we must be actively anti-racist. I think international STEM research programs such as this one should hold spots specifically for students of color, students with disabilities, and other folks who are traditionally marginalized and underrepresented in STEM to attend. Programs like this are critical for early-career scientists to network with each other and the leading scientists in the field, and without holding doors open for marginalized students, how else will diversity in STEM increase?

Volunteering at Amherst Regional Middle School

Dipa here-

This past December, I got the opportunity to share my research and interests in climate change with a group of curious middle schoolers at Amherst Regional Middle School in Amherst, Massachusetts!

The school partners with University of Massachusetts Amherst Graduate Women in STEM (science, technology, engineering, mathematics) organization to connect graduate researchers to middle school students through 20-minute Science SoundByte presentations. The 7th and 8th grade students get to enjoy the presentations during their lunch times and learn about a variety of STEM research. As for me, I get to practice explaining my research and sharing my interests to the next generation of researchers.

While I was planning my presentation I knew I wanted to get these students thinking about climate change, since it is a problem that affects them too. The students talked with each other and then shared out what they knew about climate change, sea level rise, and their impacts on the environment–they knew so much! To explain how I use fossils to study climate change in the past, I gave the students marine fossils (fossil shark teeth, mollusks, ammonites, and corals) and asked them to draw the organism and its habitat. Did it live in the reef, open ocean, at the seafloor, or in the water column? If these fossils were found in the same location, what does this say about sea level over time in that place?

The students had fun getting to touch and look at fossils, and they worked together to solve how much sea level rose over time for the activity! It was great to be back in front of a class and talk to students about their interests in STEM and how we can work together to understand modern climate change.
