Human activities have enhanced nutrient delivery to coastal ecosystems in the northern Gulf of Mexico which has increased primary productivity and resulted in the development of an oxygen-limited “dead zone.” By comparing populations living in the region today with the remains of historical populations preserved in seafloor sediments, we can determine the impacts of anthropogenic environmental change on marine life. Participating students will collect samples of seafloor sediments on research vessels offshore Louisiana, Alabama, and Florida and then analyze those samples in the Paleobiology Lab back at Colgate. Approximately five weeks will be spent conducting fieldwork and five weeks in the lab gathering and analyzing data. In the lab, we will use light microscopy and scanning electron microscopy to gather data on the biological characteristics of past and present marine invertebrate populations (e.g., egg size, body size, species composition). Students will learn to use the R programming language to explore their data and conduct quantitative analyses. Individual student research projects will help to establish historical baselines for the diversity, abundance, and characteristics of marine mollusks prior to the onset of industrial agriculture and commercial fishing.
All students interested in STEM are encouraged to apply, including first and second year students who have yet to declare their major(s). The Geology Department encourages students interested in summer research to meet with potential faculty supervisors before submitting an application. Proof of COVID-19 vaccination may be required, due to this project's off-campus components.
