Deglaciation of the Western Margin of the Greenland Ice Sheet

The Greenland Ice Sheet (GIS) is shrinking today in response to the warming atmosphere and ocean. The GIS holds enough freshwater to raise sea level by 7.4 meters (24 feet) if it melted completely. Thus, understanding how it responds to warming is important. In this project we are investigating GIS vulnerability by studying how the GIS responded to climate warming in the past. At the end of the last ice age, about 20,000 years ago, the western GIS margin extended farther into Baffin Bay, hundreds of kilometers west of its present position.

Lab upgrades and a new website

It is an exciting time for the LDEO Paleomagnetics Lab as we make progress on needed electric upgrades and get ready to install our Helium Free 2G Enterprises Long Core Magnetometer, recently donated to Columbia University from ETH Zurich.  At the same time, we are launching this website and growing with new hires.  Stay tuned to this website for more updates in the future.
