Probing paleorecords to understand future climates with Brittany Hupp
from GeOCHemISTea · host Sam Scher
Join us this month on GeOCHemISTea as we sit down with Brittany Hupp, Assistant Professor at George Mason University in the Department of Atmospheric, Oceanic, and Earth Sciences. Brittany specializes in micropaleontology, sedimentology, and low-temperature geochemistry, exploring ancient climates and ocean conditions to better understand modern environmental challenges.In this episode, Brittany shares her unconventional path into geosciences—from a dairy farm in rural Ohio to oceanic research cruises—and offers practical advice for aspiring geochemists seeking interdisciplinary careers. She introduces listeners to the Paleocene-Eocene Thermal Maximum (PETM), a pivotal ancient global warming event used as a critical analog to current climate change. Brittany explains how geochemical proxies, such as stable isotopes and trace elements in microfossils (foraminifera), illuminate past temperature shifts, ocean acidification, and hydrological changes.Tune in for captivating stories from life at sea, including the social dynamics aboard research vessels, and discover how paleoclimatology provides valuable insights into Earth's climate sensitivity and future scenarios.Grab your tea... it's time to spill!For this episode we read:The Paleocene-Eocene Thermal Maximum: A Perturbation of Carbon Cycle, Climate, and Biosphere with Implications for the Future (McInerney and Wing, 2011)Diagenetic Attenuation of Carbon Isotope Excursion Recorded by Planktic Foraminifers During the Paleocene-Eocene Thermal Maximum (Kozdon et al., 2018)Development of a novel empirical framework for interpreting geological carbon isotope excursions, with implications for the rate of carbon injections across the PETM (Turner and Ridgwell, 2016)Individual foraminiferal analyses: a review of current and emerging geochemical techniques (Fehrenbacher et al., 2024)
