Biological Productivity and Foraminifera Microfossils: A Fingerpri... | Megan Hansen | RRS Live 2025

Megan Hansen is a Sophomore Marine Science, Chemistry major in the Randall Research Scholars Program (RRSP). Their research project presentation, "Biological Productivity and Foraminifera Microfossils: A Fingerprint of Past Ocean and Glacier Conditions Offshore Antarctica," was completed under the advisement of Rebecca Totten from the Geological Sciences Department. Project Description: This project is targeting analysis of the remains of small, single-celled organisms called foraminifera, and use their population assemblages as a proxy for past climatic conditions from Cranton Bay, a small bay offshore West Antarctica. Alongside radiocarbon ages of the sediment archive, grain size as a proxy for glacial influences, and stable isotopes as a proxy of productivity and nutrients, foraminifera assemblages will be used to reconstruct past conditions in the bay. Understanding ocean and climate drivers of glacial stability can help us predict the response of the West Antarctic Ice Sheet to warming.
