9410849 Morison 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. ***

9410849莫里森这个项目是对作为威德尔海西部海洋结构综合研究方案的一部分而获得的数据集的分析。这项野外工作是1992年2月至6月在美国和俄罗斯科学家共同占领的一个冰营地进行的。首席调查员获得的数据集的目标是确定韦德尔环流西部的垂直和水平温盐通量。具体地说，能够直接测量雷诺应力和湍流热通量的仪表组悬浮在营地的冰面上，并在整个漂移过程中保持不变。此外，还部署了一个用于测量上层海洋温度、盐度和海流结构的远程浮标，以观测嵌入湍流数据的更大尺度的可变性，预计这将对湍流强度产生一些影响。该分析计划将与其他同时进行的实验一起进行，以量化带到冰层下面的能量，努力实现追踪从海洋通过海冰覆盖到大气的能量流量的总体目标。***
