This collaborative study between H.T. Harvey & Associates, Associated Scientists at Woods Hole, Inc., and R.G. Ford Consulting will combine and synthesize the distribution and occurrence patterns of highly mobile marine birds and cetaceans, as one of several data synthesis and modeling components that are based on the data obtained in the course of the field work of the Southern Ocean Global Ocean Ecosystems Dynamics (SO GLOBEC) experiment.Seabirds and cetaceans are long-lived, highly mobile, and highly visible top-predators that, except during breeding seasons, occur where prey is abundant and/or foraging efficiency is high. Therefore, these highly visible, mobile predators have proved to be sensitive indicators of where the middle portion of food webs are rich and available. This work will identify the degree to which the mesoscale integrative studies of the SO GLOBEC experiment apply toward interpreting patterns from a larger circumpolar perspective.SO-Globec is a multidisciplinary effort focused on understanding the physical and biological factors that influence growth, reproduction, recruitment and survival of Antarctic krill (Euphausia superba). The program uses a multi-trophic level approach that includes the predators and competitors of Antarctic krill, represented by other zooplankton, fish, penguins, seals, and cetaceans. It is currently in a synthesis and modeling phase. This collaborative project is concerned with understanding how the spatial distribution of top predators can be used to infer the distribution of krill and other mid-level prey, and will be integrated with other synthesis and modeling studies that deal with the hydrography, primary production, and krill dynamics.

这项合作研究之间的H. T。哈维协会，伍兹霍尔公司的联合科学家，和R.G.的组合。福特咨询公司将联合收割机结合和综合高度移动的海鸟和鲸目动物的分布和出现模式，作为根据南大洋全球海洋生态系统动态实地工作过程中获得的数据进行数据综合和建模的几个组成部分之一。（SO GLOBEC）实验.海鸟和鲸目动物寿命长，移动的多，是非常显眼的顶级掠食者，除繁殖季节外，发生在猎物丰富和/或觅食效率高的地方。 因此，这些高度可见的、移动的捕食者被证明是食物网中间部分丰富和可用的敏感指标。 这项工作将确定在何种程度上的中尺度综合研究的SO GLOBEC实验适用于解释模式从一个更大的环极prospects.SO-GLOBEC是一个多学科的努力，侧重于了解影响南极磷虾（南极磷虾）的生长，繁殖，招聘和生存的物理和生物因素。该计划采用多营养级方法，包括南极磷虾的捕食者和竞争者，以其他浮游动物，鱼类，企鹅，海豹和鲸目动物为代表。 目前正处于综合和建模阶段。这个合作项目关注的是了解顶级捕食者的空间分布如何被用来推断磷虾和其他中层猎物的分布，并将与其他综合和建模研究，处理水文，初级生产和磷虾动态。
