Identifying the basic habitat requirements of Antarctic predators is fundamental to understanding how they will respond to the human-induced challenges of commercial fisheries and climate change. This understanding can only be achieved if the underlying linkages to physical processes are related to animal movements. As part of the international Retrospective Analysis of Antarctic Tracking Data (RAATD) organized by the SCAR Expert Group of Birds and Marine Mammals, this research will collate and synthesize tracking data from crabeater seals, Lobodon carcinophagus, and Weddell seals, Leptonychotes weddelli. These data will be combined with all available data from the Southern Ocean that has been collected by researchers from Norway, United Kingdom, Germany, Australia and the USA. These data will be analyzed using a common analytical approach and synthesized into a synoptic view of these two species across the Southern Ocean. The diving and movement patterns will be examined for each species. As well, the total home range and core habitat utilization patterns for each species and region will be determined. This study will develop global habitat maps for each species based on physical and biological attributes of their "hot-spots" and then overlay all the species specific maps to identify multi-species areas of ecological significance. Broader impacts include support and training for a postdoctoral scholar, the production of a publicly available database and the participation in an international data synthesis effort.

确定南极捕食者的基本栖息地要求，对于了解它们将如何应对人类引起的商业渔业和气候变化挑战至关重要。只有在与物理过程的基本联系与动物运动有关的情况下，才能实现这种理解。作为由鸟类和海洋哺乳动物SCAR专家组组织的国际南极跟踪数据回顾分析(RAATD)的一部分，这项研究将整理和综合来自蟹海豹、食癌海豹和韦德尔海豹的跟踪数据。这些数据将与挪威、英国、德国、澳大利亚和美国的研究人员从南大洋收集的所有现有数据结合在一起。这些数据将使用共同的分析方法进行分析，并综合成南大洋上这两个物种的概貌。我们将研究每一物种的潜水和运动模式。此外，还将确定每个物种和地区的总栖息地范围和核心栖息地利用模式。这项研究将根据每个物种的物理和生物属性，为每个物种绘制全球栖息地地图，然后叠加所有物种特定地图，以确定具有生态意义的多物种区域。更广泛的影响包括对博士后学者的支持和培训、制作公开可用的数据库以及参与国际数据综合工作。
