This collaborative study between the Desert Research Institute, the University of California, Santa Barbara (0529087; Robin Ross), and the University of California, San Diego (0528728; Maria Vernet) will examine the relationship between sea ice extent along the Antarctic Peninsula and the life history of krill (Euphausia superba), by developing, refining, and linking diagnostic datasets and models of phytoplankton decreases in the fall, phytoplankton biomass incorporation into sea ice, sea ice growth dynamics, sea ice algal production and biomass accumulation, and larval krill energetics, condition, and survival. Krill is a key species in the food web of the Southern Ocean ecosystem, and one that is intricately involved with seasonal sea ice dynamics. Results from the Southern Ocean experiment of the Global Ocean Ecosystems Dynamics program (SO-Globec) field work as well as historical information on sea ice dynamics and krill recruitment suggest a shift in the paradigm that all pack ice is equally good krill habitat.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 the lower trophic levels, and will be integrated with other synthesis and modeling studies that deal with grazers, predators, and other higher trophic levels.

这项由沙漠研究所、加州大学、圣巴巴拉分校（0529087;罗宾·罗斯）和加州大学圣地亚哥分校（0528728; Maria Vernet）将研究南极半岛海冰范围与磷虾生活史之间的关系（Euphausia superba），通过开发、改进和连接秋季浮游植物减少的诊断数据集和模型，浮游植物生物量并入海冰，海冰生长动态，海冰藻类生产和生物量积累，以及磷虾幼体的能量、状态和存活率。磷虾是南大洋生态系统食物网中的一个关键物种，与季节性海冰动态密切相关。全球海洋生态系统动力学方案南大洋实验的结果（SO-Globec）的实地工作以及海冰动态和磷虾补充的历史信息表明，所有浮冰都是同样良好的磷虾栖息地的范式发生了转变。SO-Globec是一个多学科的努力，专注于了解影响生长，繁殖，南极磷虾（Euphausia superba）的招募和生存。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较低的营养水平，并将与其他综合和建模研究，处理食草动物，捕食者，和其他较高的营养水平。
