Ongoing Research Projects


Read about our project to collect bedrock cores from beneath the Greenland Ice Sheet. These cores will help us determine the last time the Greenland Ice Sheet disappeared. 

We Support JEDI

We believe in Justice, Equity, Diversity and Inclusion in Geosciences, one of the least diverse STEM communities in the US and beyond. We recognize that we failed Sciences and our community over the last decades, and define the JEDI goals as central challenges for our community, for Lamont and for the Cosmo Group. We endorse the Lamont Black Lives Matter-Anti-Racism commitment as well as the Lamont Code of Conduct.
