The project will be building habitat models from two sets of tracking data from two colonies of Antarctic fur seals, one in South Georgia and one on the Antarctic peninsula. It will also utilise stable isotope analyse on whiskers and seal teeth from these colonies that have been collected over the last 100 years. This should give us data on how their diet and nutrition has changed over time. One colony on South Georgia has a population that is in decline, this study could help identify possibilities for this decline.

该项目将根据来自两个南极海豹栖息地（一组位于南乔治亚岛，一组位于南极半岛）的两组跟踪数据来构建栖息地模型。它还将对过去 100 年来收集的这些群体的胡须和海豹牙齿进行稳定同位素分析。这应该为我们提供有关他们的饮食和营养如何随时间变化的数据。南乔治亚岛的一个殖民地的人口正在下降，这项研究可以帮助确定这种下降的可能性。
