Brigham-Grette has participated in international scientific collaborations, including the Lake El'gygytgyn Drilling Project in Northeastern Russia that examined past Arctic climate conditions.[4]
Brigham-Grette received her PhD from the University of Colorado Boulder in May 1985, with the dissertation "Marine Stratigraphy and Amino Acid Geochronology of the Gubik Formation, Western Arctic Coastal Plain, Alaska."[8] Her graduate degrees incorporated the technique of amino acidgeochronology (amino acid dating),[9][10] which estimates the time passed since the death of an individual organism based on the changes in indigenous proteins preserved in carbonate shells.[11] Brigham-Grette utilized this technique to correlate regional stratigraphic sections to resolve glacial geologic and sea-level history.
Research and career
Following her graduate work, Brigham-Grette was a Postdoctoral Research Fellow at the University of Bergen from November 1983 to December 1984, where she collaborated with Dr. Hans-Petter Sejrup on the Geochronology of Quaternary sediments in the North Sea.[12]
In 1987, she became an assistant professor at the University of Massachusetts Amherst in what was then the Department of Geology & Geography (now Geosciences). Brigham-Grette was a visiting professor at the Alaska Quaternary Center, University of Alaska Museum of the North, Fairbanks, from January to June 1990.[14] In 1993, she became the third tenured female faculty member in the Department of Geosciences at the University of Massachusetts Amherst,[15] and was promoted to professor in 2001. Brigham-Grette teaches courses in glacial geology, Quaternary glacial stratigraphy, geochronology, and oceanography. Brigham-Grette is the first woman to serve as the Graduate Program Director for the Department of Earth, Geographic, and Climate Sciences at the University of Massachusetts Amherst (2013–present).[16]
Brigham-Grette has served in numerous leadership roles in the international Arctic science community. She has been a member of the Polar Research Board of the National Academy of Sciences since 2008 and the board’s chair since 2014.[17][18] She co-chaired the DOSECC Scientific Steering Committee to direct the renewed US Continental Drilling Program from 2010 to 2012 and was Vice-Chair of the DOSECC Board of Directors from 2011 to 2013. Since 2013, Brigham-Grette has been a member of the American Geophysical Union (AGU) Governance Board.[19]
Brigham-Grette received grants to study Lake Elgygytgyn in 1996 and 2000.[21][22] She was also one of the principal investigators in the 2009 Lake Elgygytgyn drilling project, which received funding in 2005.[23] This project led to the recovery of the lake's sedimentary sequence. Data from the drilling project was used in papers about both the Pleistocene's and later the Pliocene's arctic climate.[24][25]
Teaching and outreach
Brigham-Grette teaches about Arctic climate change. Since 2003, Brigham-Grette has been a leader or co-leader of a Research Experiences for Undergraduates (REU) training program in Svalbard (Norway).[26] This program provides undergraduates with hands-on research investigating the links between climate, glacial mass balance, sediment transport, and lake and fjord sedimentation from a location that has experienced warming over the past 90 years.[27] Brigham-Grette has worked with four teachers since 2009 as part of Polar TREC,[28][29] a program that brings high school teachers to the Arctic to participate in field research expeditions.
