Project aim
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 study aims to investigate the influence of winter sea ice extent on a top Antarctic predator, the Weddell seal (Leptonychotes weddellii). This will be a 12-month pilot study investigating the winter movements of adult female Weddell seals. These data will enable us to assess the feasibility of using Weddell seals in a long-term study of winter sea-ice and predator performance.
