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.
