The P-Mag lab continued investigating the history of the Greenland Ice Sheet this summer, collecting lake cores and cosmogenic nuclide samples from the South Greenland margin. Brendan Reilly joined Gaylen Sinclair (PhD student, OSU) and spent about 2 weeks at a remote field location, 17 miles from the town of Narsaq. Gaylen, with CEOAS’s Anders Carlson, targeted this study area due to its unique geology, anticipating that the lake stratigraphy and glacial landforms will reflect the glacial and climate history of the past few thousand years. According to Gaylen, “Understanding how the ice sheet behaved in the past will help us understand it’s sensitivity to climate change, or how much and how quickly the ice advances and retreats in response to a change in climate.“
It was an eventful trip, including traveling by small boat through the icy Greenland fjords, weathering a major storm, experiencing the Aurora Borealis, and hiking through the rugged Greenland landscape. We look forward to what story the analysis of these unique samples reveal!
