Collaborative Research: Western Weddell Ice Station Turbulence and Mixed Layer Project

这个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，在美国和俄罗斯科学家共同占领的一个冰营进行了实地工作。首席研究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。具体来说，能够直接测量雷诺应力和湍流热通量的仪器集群悬挂在营地的冰上，并在整个漂流期间保持不变。此外，还放置了一个远程浮标，用于测量上层海洋的温度、盐度和洋流结构，以观测湍流数据所包含的更大尺度的变率，预计这将对湍流强度产生一些影响。该分析项目将与其他同时进行的实验一起进行，以量化带到冰底的能量，朝着追踪从海洋通过海冰覆盖到大气的能量通量的总目标努力。＊＊＊

9410848 McPhee 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. ***
