Advancing non-destructive analysis of sub-ice sediments to reconstruct Greenland’s ice-free past
Abstract
My research improves methods for extracting paleoenvironmental data from sub-ice sediments, focusing on the Camp Century ice-core’s four meters of sediment. Using cryo- X-ray micro-CT scanning, a non-destructive imaging technique, I analyze sediment shape, size, and microstructures, which help determine key parameters like ice-to-sediment ratio and depositional changes, revealing past environmental conditions when Greenland was ice-free. By enhancing ice-core analysis, my work advances our understanding of Greenland’s climate history and improves predictions of ice sheet responses to future warming.
