Western Greenland Surface Exposure Dating & Glacial Geomorphology
PI(s):
Paleoclimatic trends in the polar region have become increasingly important following the recognition of a probable polar amplification to global warming. High latitude feedback mechanisms play an important role in the climate system, but in the absence of long term meteorological records, natural climate variability and feedback mechanisms remain poorly understood. Arctic areas are rich in glacial features of all sizes and their deposition time and mode contain one of the few continuous archives for deciphering past climate variability in present-day arid continental subarctic areas. Ice margins are highly sensitive to climate change and Surface Exposure Dating (SED) offers a direct insight into the final time when ice was present above glaciated features. This proposal asks for support for a start-up project that aims to link the glacial dynamics of the Isunguata Sermia Glacier to climate change during the Holocene.
