Ellen E. Martin is Professor and Chair at the University of Florida, specializing in paleoceanography and paleoclimatology using radiogenic isotope systems. She holds a Ph.D. in Oceanography from Scripps Institution of Oceanography (UC San Diego). Her research investigates connections between ocean circulation, chemical weathering, and climate change using Nd and Pb isotopes in deep-sea sediments.
Current projects examine how glacial retreat in Greenland influences chemical weathering patterns, nutrient delivery, and carbon sequestration. Dr. Martin's work also reconstructs deglacial water mass changes in the Southern Indian Ocean and documents methane cycling in subglacial environments. Her research links deep-sea geochemical records with continental erosion processes to understand Earth's carbon cycle responses to climate transitions.
Fieldwork focuses on Greenlandic watersheds to quantify weathering fluxes across deglaciated chronosequences. Analytical approaches integrate isotopic tracers with foraminiferal proxies to reconstruct past ocean circulation changes and their role in atmospheric CO2 variations during glacial terminations.
