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.

该项目将从两个南极海豹菌落，一个在乔治亚州的两个菌落，一个在南极半岛上建立栖息地模型。它还将利用过去100年收集的这些菌落的晶须和密封齿的稳定同位素分析。这应该为我们提供有关他们的饮食和营养如何随着时间而改变的数据。乔治亚州南部的一个殖民地人口正在下降，这项研究可以帮助确定这种下降的可能性。
