Assistant Professor of Geology Bess Koffman coauthored a paper in the Journal of Geophysical Research: Atmospheres. Titled “Denali ice core methanesulfonic acid records North Pacific marine primary production,” the paper focuses on developing a tool for assessing past changes in primary production in the North Pacific, i.e., the base of the marine food web. The paper developed from the senior thesis project of David Polashenski, who Koffman worked with at Dartmouth College (along with Erich Osterberg). Using the 1200-year ice core methanesulfonic acid (MSA) record, they hope to provide long-term climate context for modern observations of declines in primary production.
