Collaborative Research: West Antarctic Ice Sheet Stability: The Glacial Geologic Record From The Ohio Range Of The Horlick Mountains In The Bottleneck, Harold W. Borns Jr.
University of Maine Office of Research Administration: Grant Reports
This award supports a project to document former high stands and assess the stability of the West Antarctic ice sheet (WAIS) at the Ohio Range near the head of Mercer Ice Stream (formerly Ice Stream A). The field location is situated in the "Bottleneck", a unique, relatively narrow passage in the Transantarctic Mountains connecting the West and East Antarctic ice sheets. The location lies near the ice divide and is thus well situated to determine past interior ice elevation. The research will involve geologic mapping of glacial deposits and erosion features combined with cosmogenic surface exposure dating on the Ohio …
