Research

Major Research Interests

Remote sensing of glaciers

Development of new spaceborne and airborne techniques for mapping surface properties of glaciers

Dynamics of snow cover

Including the development of new monitoring techniques and the analysis of regional and circumpolar datasets. Currently part of a collaboration with British Antarctic Survey.

Dynamics of high-latitude vegetation

Long-term collaborative programme, with the Geography Faculty of Moscow State University, to develop and apply spaceborne monitoring techniques to tundra and forest change in the Russian Arctic and elsewhere as a consequence of climate change, airborne industrial pollutants and anthropogenic factors including reindeer husbandry.

PPS Arctic / Tundra-Taiga Initiative

International programmes to study the current status and climatological sensitivity of the tundra-taiga ecotone. More information is here.

Remote sensing of high-latitude fauna

This is a long-running research area which began with the study of reindeer in northern Russia. Currently it includes two collaborative projects with British Antarctic Survey, to study penguins and whales.

Reconstructing historical climate data from the Southern Ocean

The aim of this project is to use historical records from naval and commercial vessels operating at high southern latitudes to reconstruct ice and climate data from the southern ocean.
