MGU Conference 2022

MGU (Michigan Geophysical Union) is a 1-day conference completely run by UM students, bringing together students studying earth sciences in the Earth and Environmental Science, Chemistry, and Climate and Space Sciences and Engineering departments across campus. This has historically just been a poster session, but this year a few live talks were held as well.

The SCIPP Lab had a very strong representation at MGU 2022! ALL members of the SCIPP Lab presented (4 grad, 4 undergrad posters) and Sierra volunteered as a judge. Two of our group members (Alex and Allison) were also on the organizing committee! Everyone did an awesome job creating their posters and presenting their results. Two of our undergrads were awarded “best undergrad presentation” awards! Congratulations Cecilie and Samantha!

1st Yr PhD student Alex Quizon presents modern gastropod clumped isotope calibration data to fellow graduate student. Of all the mollusks that have been calibrated and studied for clumped isotopes, marine gastropods have been largely left out. Preliminary work shows some species may have vital effects, but others do not. Identifying good target species can open up more fossil applications. Nice work Alex!
Junior UG Samantha Davies presents her work reconstructing paleo-ocean temperatures at a new KPg boundary section in Mississippi to Professor Jenan Kharbush. She must have impressed Professor Kharbush, because she was chosen as one of the “best undergrad posters”!! We are thrilled that Samantha will be continuing this research at more Gulf Coastal Plain sites as part of her senior thesis research in the SCIPP lab next year.
Freshman UG Manmeet Singh presents his work reconstructing paleo-ocean temperatures in the Maastrichtian Gulf Coastal Plain to Iso-Paleo-Lab grad student Nick Ellis (Passey Group). Amazing job Manmeet!
4th year PhD student Jade Zhang presents her work to lab neighbor Cameron Trip (Cole group). Jade is trying to figure out the best sampling and data processing strategy to extract temperature seasonality using D47. She is testing modern bivalves from the Atlantic/Caribbean where true seasonality is known. Then she hopes to apply these methods to fossils from Bermuda from the Last Interglacial to determine past seasonality.
Freshman Cecilie Phillips presents her work to an Earth graduate student. Cecilie is working with PhD student Alex Quizon to reconstruct past ocean temperatures and seasonalities up and down the US East Coast during the Last Interglacial. Cecilie analyzed fossil clams of the genus Mercenaria at subannual resolution and found growth shut offs at colder temperatures in the high latitude sites. We are excited that Cecilie will be staying on to work in the SCIPP Lab next year to continue this project!
Junior Sabrina Lanker explains her poster to SCIPP Lab grad student Lucas Gomes. Sabrina has been working with PhD student Jade Zhang to look at seasonality in fossil bivalves from Bermuda dating to the Last Interglacial. Nice work Sabrina!
1st YR PhD student Lucas Gomes presents his work on climate in the early Pleistocene of Florida. Lucas is using high resolution (subannual) clumped isotope sampling to reconstruct mean annual conditions, and seasonality of temperature and d18Owater from a Plio-Pleistocene section in central Florida. This preliminary data will be leading to new field work in early May to collect more samples from this site. Can’t wait to continue and grow this project!
3rd Yr PhD student Allison Curley explains her work on isotopic vital effects in bivalves to Professor Jena Johnson. Allison is studying mechanisms that produce different isotopic signatures in bivalve shells and how they can tell us about physiology, potentially in extinct taxa! Can’t wait to see this work published (soon!). Nice job Allison.

And a silly one too 🙂
