See the link below for public details on this project.

Variations in the winter extent of sea ice are thought to have profound effects on biological productivity, such as algal growth and the reproduction of Antarctic krill, with subsequent flow-on effects through the food web. This pilot study aims to measure the winter foraging patterns of Weddell seals (Leptonychotes weddellii) as a first step in investigating their role in the winter sea-ice zone. Our specific objectives are to:

1. Obtain satellite tracks from a sample of adult female Weddell seals
2. Collect diving behaviour (dive depth, duration and frequency) from a sub-set of these seals
3. Collect high precision water temperature data from a subset of these seals

These data will enable us to assess the feasibility of including Weddell seals as a candidate species in a long-term study of winter sea-ice and predator performance.
