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.

该项目将根据两个南极海狗栖息地的两组跟踪数据建立栖息地模型，一个在南乔治亚岛，另一个在南极半岛。它还将利用稳定同位素分析从这些群落收集的胡须和海豹牙齿，这些胡须和海豹牙齿是在过去100年里收集的。这将为我们提供他们的饮食和营养随时间变化的数据。南乔治亚岛的一个种群数量正在下降，这项研究可以帮助确定这种下降的可能性。
