Field Activity 2023-639-FA

Identifier 2023-639-FA
Alternate names SKQ202311S
Purpose We plan to collect and analyze sediment cores from five submarine sedimentary basins on the Bering Sea shelf which may have been occupied by freshwater lakes during the last glacial maximum. Our objectives include reconstructing the vegetation of the emergent Bering Land Bridge and evaluating the relationship between sea ice extent during the Pleistocene and Holocene.
Location Bering Sea
Info derived Our team will analyze the cores using methods from diatom micropaleontology, palynology, organic geochemistry, sedimentology, and ancient DNA.
Comments This project is funded by NSF Grant OPP-2117052 to the University of Alaska Fairbanks. The research team will spend ~4 weeks at sea aboard the R/V Sikuliaq collecting data from the Bering Sea continental shelf. All sediment cores will be archived at Oregon State University.
