Julie Brigham-Grette is an American glacial geologist and professor in the Department of Geosciences at the University of Massachusetts Amherst.[3] Her research focuses on Arctic paleoclimate and Quaternary glacial history, including work on lake and marine sediment records in Beringia and the Bering Strait region.[4]

Early life and education

Brigham-Grette earned a BA in geology from Albion College in 1976, graduating magna cum laude.[5] She completed an MS in geology at the University of Colorado Boulder in 1980 with a thesis on Quaternary sediments at Broughton Island, Baffin Island,[6] and a PhD at the same institution in 1985 on the Gubik Formation of Alaska’s Arctic Coastal Plain.[7] Her graduate work applied amino acid dating to carbonate fossils in support of Quaternary correlation and sea-level history.[8]

Research and career

Brigham-Grette joined the faculty at UMass Amherst in 1987 (then the Department of Geology & Geography, now Geosciences).[9] She has led or co-led multiple field campaigns in Arctic Russia and Alaska and has been a co-director of the Joseph Hartshorn Quaternary Laboratory at UMass.[10]

A significant part of her work involves the Lake El’gygytgyn Drilling Project in northeastern Russia. The project recovered a continuous sedimentary sequence that has been used to reconstruct Arctic climate over the last 2.8 million years.[11][12] Earlier project overviews describe the logistics and objectives of the drilling effort.[13]

Brigham-Grette has held leadership roles in polar and Quaternary science organizations. She was appointed chair of the Polar Research Board of the National Academy of Sciences in 2014,[14] and has served in AGU governance,[15] among other committee and panel roles.[16]

Research contributions

Brigham-Grette’s work has applied amino-acid geochronology to Quaternary stratigraphy and sea-level history,[17] and contributed to reconstructions of Arctic climate variability using lacustrine records from Lake El’gygytgyn.[18][19] She has been principal investigator on National Science Foundation awards related to Arctic paleoclimate and undergraduate research training in Svalbard.[20][21][22]

Teaching and outreach

At UMass Amherst, Brigham-Grette has taught courses in glacial geology, Quaternary stratigraphy, geochronology, and oceanography.[23] She has also participated in public and educator outreach related to Arctic climate, including talks and media appearances connected to the Lake El’gygytgyn project.[24]
