Currently funded projects in the Glacial History Lab include:

1) The GreenDrill Project [project website]

2) The GRate Project, which builds on the Snow on Ice Project [project website]

3) The Ghub Project [Ghub website]

Below is a list of the types of research we do, and the areas in which we work. Current funded research involves most of these investigations.

Fluctuations of the Greenland Ice Sheet during the Holocene

We use cosmogenic nuclide analysis (mostly 10Be dating) to reconstruct the history of Greenland Ice Sheet margins.

We use sediment records from proglacial-threshold lake basins to fix the position of the Greenland Ice Sheet margin during periods of time in which it was smaller than it is at present.

Dating Pleistocene and Holocene glaciation in Alaska

We reconstruct the extent and history of glaciation throughout Alaska (Brooks Range, Alaska Range, Southeast Alaska, etc.).

We investigate proglacial lake sediments as archives for upvalley alpine glacier changes.

Glacier history of Baffin Island, Arctic Canada

We have a long-standing interest in reconstructing glacier change on Baffin Island during the latest Pleistocene and Holocene. Recent work is focused on fjord deglaciation and Holocene abrupt climate change.

We reconstruct climate change from lacustrine archives on Baffin Island, using varves and biomarker proxies to investigate Holocene climate change and Neoglaciation.

Deglaciation of the Fennoscandian Ice Sheet

The deglaciation of the Fennoscandian Ice Sheet and the Norwegian Channel Ice Stream, and ice margin advances during overall retreat, are currently being reconstructed.


In the cosmogenic isotope lab, we analyze rock samples from glacial terrains to date glacial features and determine ice sheet processes.

In the lake sediment lab, we analyze biological, chemical and physical properties of lake sediment to study arctic paleoclimate.
