Marine Geology and Geophysics Seminar, April 25

Speaker Kelsey Doiron, Ph.D., NSF Ocean Sciences Postdoctoral Fellow, Harvard University New Perspectives in the Application of Alkenones as Paleoenvironmental Proxies in Marine and Lacustrine Setting Abstract Alkenones are a biomarker widely used in paleoceanography as proxies for reconstructing sea surface temperatures (UK37’) and pCO₂ levels, offering valuable insights into Cenozoic climate change through marine […]

Speaker Jordan Wostbrock, Ph.D., Assistant Professor, Yale University Reconstructing paleoenvironments using triple oxygen isotope values Abstract The increase of d18O values in the rock record (where older samples have lower d18O values than modern) has been attributed to changing ocean temperature, an increase in the d18O value of the ocean water, or diagenesis obscuring paleoenvironmental […]

Marine Geology and Geophysics Seminar, April 11

Speaker Wenxiu Teng, Ph.D. Candidate, UMass-Amherst Assessing Marine-Sourced Sediment Supply and Its Influence on Salt Marsh Resilience to Sea Level Rise Using Satellite Observations Abstract Suspended sediment delivery is a key driver in the formation and maintenance of muddy coastal landscapes such as river deltas, mudflats, and tidal wetlands. While the critical role of riverine […]

Marine Geology and Geophysics Seminar, March 7

Speaker James Dottin III, Ph.D., Assistant Professor, Brown University Hydrogen Isotopic Evidence for a Core Component in Baffin Island Lavas Abstract The nature of chemical exchange between Earth’s core and mantle is fundamental to understanding their evolution. Tungsten-182 and helium-3 anomalies in volcanic rocks from deeply sourced mantle plumes have been attributed to core-mantle exchange. […]
