This collaborative study between the Polar Oceans Research Group, Old Dominion University, and the University of Wisconsin-Madison will identify and investigate the causal mechanisms through which changes in sea ice and variability in the western Antarctic Peninsula marine ecosystem affect recruitment in Adelie penguin populations.The approach combines data collection, extensive data analyses, and the development of a bioenergetics model of penguin chick growth that provides a framework for investigating the physical and ecological factors that determine chick fledging weight, which is linked to recruitment success. The available data base spans 30 years at Palmer Station, and four major research programs, including the Southern Ocean experiment of the Global Ocean Ecosystems Dynamics program (SO-Globec). 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 specifically with the sea ice dynamics that constrain ecological processes, and will be integrated with other synthesis and modeling studies that deal with primary producers, grazers, predators, and other higher trophic levels.

极地海洋研究小组，旧自治领大学和威斯康星大学 - 麦迪逊分校之间的这项合作研究将识别和调查因果机制，通过这些机制，南极西部半岛海洋生态系统的海冰和可变性的变化会影响Adelie Penguin人群的招聘。用于研究决定雏鸡体重的物理和生态因素，这与招募成功有关。 可用的数据库跨越了帕尔默车站30年，以及四个主要的研究计划，包括全球海洋生态系统动力学计划（SO-Globec）的南洋实验。 So-Globec是一项跨学科的努力，旨在理解影响南极奎师（Euphausia Superba）的生长，繁殖，招募和生存的物理和生物学因素。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。这个协作项目特别与限制生态过程的海冰动力学有关，并将与其他合成和建模研究集成，这些研究与主要生产者，放牧者，捕食者和其他更高的营养水平有关。
