In this episode of The Coastal Call, host Rob Nazarian welcomes Dr. Frank Nitsche of the Lamont-Doherty Earth Observatory and the Columbia University Climate School, along with Professor Tyler Griffin, assistant professor of biology at Fairfield, for a conversation about what the seafloor can teach us about Earth’s past, and what it can reveal about our future. Dr. Nitsche breaks down marine geophysics, from sonar mapping and seismic tools to the power of 3D data visualization. He shares fieldwork insights from Long Island Sound, the Hudson River, and Antarctica, including how scientists reconstruct glacial retreat to strengthen today’s ice-sheet models. The episode also explores emerging tools like AI, big-data workflows, and autonomous vehicles, along with advice for students interested in research careers.

In this episode of The Coastal Call, host Rob Nazarian and guest co-host Aishwarya Krutukulam speak with Dr. Penny Vlahos, a biogeochemist at the University of Connecticut, about what Long Island Sound can teach us about coastal change and community resilience. Dr. Vlahos explains how carbon and nitrogen cycling shape water quality, why the western Sound is more vulnerable to hypoxia and seasonal acidification, and how warming trends could reverse some restoration gains over time. She also discusses what effective collaboration looks like across science, policy, and public advocacy, as well as how hands-on research and mentorship can spark student curiosity and create long-term impact.
