The U.S. Global Ocean Ecosystems Dynamics (U.S. GLOBEC) program has the goal of understanding and ultimately predicting how populations of marine animal species respond to natural and anthropogenic changes in climate. Research in the Southern Ocean (SO) indicates strong coupling between climatic processes and ecosystem dynamics via the annual formation and destruction of sea ice. The Southern Ocean GLOBEC Program (SO GLOBEC) will investigate the dynamic relationship between physical processes and ecosystem responses through identification of critical parameters that affect the distribution, abundance and population dynamics of target species. The overall goals of the SO GLOBEC program are to elucidate shelf circulation processes and their effect on sea ice formation and krill distribution, and to examine the factors which govern krill survivorship and availability to higher trophic levels, including penguins, seals and whales. The focus of the U.S. contribution to the international SO GLOBEC program will be on winter processes. This component will focus on the large-scale distribution, abundance and habitat of seabirds. This will be accomplished using strip-transect surveys and spatial analysis software and models to examine the large-scale data. This research will be coordinated with seabird studies which focus on seabird diet composition and small scale foraging behavior. The result of the integrated SO GLOBEC program will be to improve the predictability of living marine resources, especially with respect to local and global climatic shifts.

美国全球海洋生态系统动力学（美国环球环节）计划的目标是理解并最终预测海洋动物物种的种群如何应对气候中的自然和人为变化。 南大洋（SO）的研究表明，气候过程与生态系统动力学之间通过年度形成和破坏了海冰。 南大洋Globec计划（SO Globec）将通过识别影响目标物种的分布，丰度和种群动态的关键参数来研究物理过程与生态系统响应之间的动态关系。 SO Globec计划的总体目标是阐明货架循环过程及其对海冰形成和磷虾分布的影响，并检查控制磷虾生存和可用性到更高营养水平的因素，包括企鹅，海豹和鲸鱼。美国对国际比赛的贡献将放在冬季过程上。该组成部分将集中于海鸟的大规模分布，丰度和栖息地。这将使用带状调查和空间分析软件和模型来检查大规模数据。这项研究将与海鸟研究协调，该研究的重点是海鸟饮食组成和小规模的觅食行为。综合SO Globec计划的结果将是提高生活海洋资源的可预测性，尤其是在本地和全球气候变化方面。
