This collaborative project (with the Naval Postgraduate School) is a study of heat, momentum, and salinity exchange in the upper ocean as a component of the German Antarctic Program's Ice Station Polarstern (ISPOL) project, a planned fifty-day drift in the western Weddell Sea in November-December 2004. Two instrument clusters will measure the three-dimensional current, temperature, and salinity structure, to characterize the ambient oceanic turbulence structure. These data will provide the quantitative estimates of the eddy viscosity and diffusivity profiles in the upper ocean necessary for realistic modeling of scalar distributions and fluxes in the ice/upper ocean system, including fluxes of nutrients. In the event that the drift of Polarstern encounters the continental shelf, the turbulence measuring system, designed for depths in excess of 500 m, may be used for limited studies of the bottom boundary layer. This would add a useful dimension to the experiment, by making direct flux measurements in a density flow transporting cold bottom water off of the eastern Antarctic Peninsula shelf. The work continues a collaboration with scientists from the international community interested in the Southern Ocean south of 60 deg South that began with planning for Ice Station Weddell in 1990. It provides an opportunity for American participation in a German-led experiment with good potential for cross-fertilization of concepts and techniques for understanding high latitude air-sea-ice interaction. It includes partial support for a postdoctoral researcher and the opportunity to advise postgraduate thesis work.

这一合作项目（与海军研究生院合作）是对上层海洋热量、动量和盐度交换的研究，是德国南极计划冰站Polarstern（ISPOL）项目的一个组成部分，该项目计划于2004年11月至12月在威德尔海西部进行为期50天的漂流。 两组仪器将测量三维海流、温度和盐度结构，以确定周围海洋湍流结构的特征。 这些数据将提供必要的冰/上层海洋系统的标量分布和通量，包括营养物通量的现实建模的定量估计的涡动粘度和扩散率剖面。 如果Polarstern号漂流物遇到大陆架，设计用于500米以上深度的湍流测量系统可用于对底边界层进行有限的研究。这将为实验增加一个有用的维度，通过在输送南极半岛东部大陆架冷底层水的密度流中进行直接通量测量。这项工作继续与国际社会对南纬60度以南的南大洋感兴趣的科学家合作，该合作始于1990年对威德尔冰站的规划。它提供了一个机会，让美国参与德国领导的一项实验，该实验具有很好的潜力，可以相互促进了解高纬度空气-海冰相互作用的概念和技术。它包括对博士后研究人员的部分支持和为研究生论文工作提供建议的机会。
