“Recent scientific evidence across disciplines points to an unstable Greenland Ice Sheet (GrIS), which is particularly concerning in view of a rapidly changing Arctic system, its impacts on local communities and ecosystems, and the regional and global impacts of sea-level rise.”
GreenDrill will test the sensitivity of the northern Greenland ice sheet to answer critical questions like:
- How vulnerable is the ice sheet to our warming climate?
- What area of the ice sheet is most vulnerable, contributing the first few centimeters of sea level rise?
- When would we expect this to occur?
Answers to these questions are locked in the bedrock archive buried under the Greenland Ice Sheet. Pursuing answers has triggered mobilization of the first large Greenland ice drill program in over a quarter century.
GreenDrill is a 5-year, $7 million project funded by NSF that brings together researchers from Lamont-Doherty Earth Observatory, University at Buffalo, University of Massachusetts Amherst, and Penn State, and harnesses the resources of the U.S. Ice Drilling Program.
GreenDrill addresses the climate vulnerability of the northern regions of the Greenland Ice Sheet by drilling transects of 3 cores through the ice in 4 different locations.

The GreenDrill project launched in the midst of a series of unprecedented global challenges that appeared from seemingly nowhere. Project PIs Jason Briner ([email protected]) and Joerg Schaefer (LDEO) reflect on the magnitude of the project and the imperative to move the project forward and continue the work, with additional planning and collaboration.
