The LDEO Cosmogenic Dating Group, develops and refines terrestrial cosmogenic nuclides as chronometers and tracers in the Earth Sciences.
One of our core projects studies mountain glacier fluctuations -and the underlying climate drivers- across the globe from the last glacial cycle up to present day. Our goal is to understand what has driven ice-age/warm-period cycles as well as evaluating the vulnerability of mountain glaciers in our warming world, and the impact of the glacier melt on societies, energy and shelter.
A more recent project adresses the question of stability of the polar ice-sheets. We are analyzing sub-ice sheet bedrock for multiple cosmogenic nuclides, that tell us the story of past deglaciation and regrowth of these ice sheets.
