Snow On Ice

Erratics along the Greenland ice sheet

Snow on Ice takes an integrated look at Arctic climate, focusing on the linkages between the ice, ocean and atmospheric processes to consider if climate warming could contribute to stabilizing the Greenland Ice Sheet. Could the loss of Arctic Sea Ice bring unexpected changes to the Arctic hydrologic cycle? Exposed ocean water could cause cold, dry Arctic air masses to warm, bringing additional moisture to this region, some of which could fall as additional snow. Could some of this additional winter snow on Greenlan last through the summer, causing the ice sheet to stabilize? This project will bring together temperature, precipitation and sea ice cover data reconstructed from new lake sediment and ice cores covering the past 11,700 years. The data will be synthesized into an ice sheet modeling effort examining simulations of Arctic ice cover from the last 8000 years and future projections. Partner institutions include University of Buffalo, University of Washington, JPL, UC Irvine, University of Montana, Geotop and GEUS.
