Reconstructing the strength of the Westerly Winds in the Southern Ocean
In this NERC- and Swiss Polar Institute-funded project, we are generating Southern Hemisphere Westerlies (SHW) proxy records from each of the three major sectors of the Southern Ocean, focusing on subantarctic islands situated in the core belt of the SHW.

Arctic climate history
For the last 20+ years, I have been working on various projects to understand climate evolution and human impacts on the Arctic environment.
These have included projects on Ellesmere Island, Greenland, Alaska and Svalbard.
