Serendipity in Arctic Quaternary science leads to new frontiers across Beringia

Julie Brigham-Grette

Professor, Earth, Geographic, and Climate Sciences, University of Massachusetts Amherst

INSTAAR launched my Arctic research career, beginning with fieldwork on coastal Baffin Island and culminating in a traverse of the Cumberland Peninsula . Serendipity then drew me to investigate the Plio-Pleistocene sea-level h istory in the Bering Strait and the shared paleoclimate record across the Bering Land Bridge. Today using new tools and collaborations, I remained focused on synthesizing Arctic Ocean, borderland, and gateway histories and hope to convening scientists across disciplines-from mantle to atmosphere-to advance and communicate research on Beringia's role as both a high-latitude marine gateway and terrestrial bridge.

Bio - Julie Br igham-Grette (University of Massachusetts Amherst) brings 48 years (yikes) of expertise in Arctic climate change, with research grounded in the oceanic and terrestrial sediment records of Beringia. Her work spans the last several million years, including the history of Arctic sea ice, sea level, and landscape evolution in the western Arctic; she is currently collaborating with the communities of Mekoryuk and Kongiganak, Alaska, through the NSF Navigating the New Arctic Program to address present and future landscape change. Following her time at INSTAAR in 1985, she completed postdoctoral research in Bergen, Norway, on North Sea cores and then spent two years with the Geological Survey of Canada in Edmonton working in th e Beaufort Sea; she is especially proud of her 16-year leadership in drilling Lake El'gygytgyn in northeastern Arctic Russia, which recovered a 3.6-million-year record of Arctic climate evolution from the Arctic border lands.
