9316449 Martinson This project is the analysis of the data set obtained as part of an integrated research program into the oceanographic structure of the western Weddell Sea. The field work was carried out from an ice camp jointly occupied by U.S. and Russian scientists from February to June 1992. The data set obtained by the principal investigator had as its objective the definition of the vertical and horizontal thermohaline fluxes within the western part of the Weddell Gyre. Specifically, instrument clusters capable of measuring the Reynolds stress and the turbulent heat flux directly were suspended from the ice at the camp and maintained throughout the duration of the drift. Also, a remote buoy to measure upper ocean temperature, salinity, and current structure was emplaced to make observations on the larger scale variability within which the turbulence data is embedded, and which is expected to have some effect on the turbulence intensity. The analysis program will be carried out in conjunction with those of other concurrent experiments to quantify the energy brought to the underside of the ice, working toward the general goal of tracing the flux of energy from the ocean through the sea ice cover to the atmosphere. ***

9316449 Martinson本项目是对作为威德尔海西部海洋学结构综合研究计划的一部分而获得的数据集进行分析。 1992年2月至6月，美国和俄罗斯科学家在一个联合冰营地进行了实地工作。 主要调查员获得的数据集的目的是确定威德尔环流西部的垂直和水平温盐通量。 具体而言，能够直接测量雷诺应力和湍流热通量的仪器群被悬挂在营地的冰上，并在整个漂移期间保持不变。 此外，一个远程浮标测量上层海洋的温度，盐度，和电流结构进行观测的湍流数据中嵌入的更大规模的变化，预计有一些影响的湍流强度。 该分析计划将与其他同步实验一起进行，以量化带到冰底的能量，努力实现追踪从海洋通过海冰覆盖到大气的能量通量的总体目标。 ***
