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.

H.T.之间的这项合作研究Harvey＆Associates，Woods Hole，Inc。和R.G.的关联科学家福特咨询将结合和综合高度移动海洋鸟类和鲸类的分布和发生模式，这是基于在南方海洋全球海洋生态系统的现场工作中获得的数据合成和建模组件之一，这些组件是基于在现场工作过程中获得的数据（So so Globec），在繁殖过程中，高度高度培养了，以及高度培养的，以及较高的手机，移动，移动效果，以及较高的手机，移动效果。季节，猎物丰富和/或觅食效率很高的季节。 因此，这些高度可见的移动捕食者被证明是食物网中间部分丰富且可用的位置的敏感指标。 这项工作将确定SO Globec实验的中尺度综合研究适用于从较大的近极角度来解释模式的程度。So-Globec是一种多学科的工作，重点是理解影响生长，繁殖，募集，招募和抗生物的生物学因素（Euphausia superba）。该计划采用多营养水平的方法，其中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，海豹和鲸类动物为代表。 它目前处于合成和建模阶段。该协作项目涉及了解如何使用顶级捕食者的空间分布来推断磷虾和其他中层猎物的分布，并将与其他合成和建模研究集成在一起，这些研究和建模研究涉及水文，初级生产和磷虾动力学。
