Ice Station Weddell: Physical Oceanography Data Analysis Phase

9313700 Gordon这个项目是对作为威德尔海西部海洋结构综合研究计划的一部分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。首席研究员的工作是该研究计划的主要项目，涉及大规模海洋环流和威德尔海边界流的变化，以及它们如何影响和受区域水团形成和改变过程的影响。根据威德尔海的能量交换模式，威德尔海可以划分为三个区域。暖区出现在东部，温暖的环极深水的侵入使水温保持在+1℃左右。冷区出现在中心，深水被一层厚厚的接近冰点的混合层覆盖。然而，在这两个地区，季节性地有足够的热量输送到海冰，使其完全融化。在西部地区，海冰没有融化，预期的热力过程不同。水文测量数据，加上海流计观测和化学示踪实验，以及湍流通量测量和海冰动力学，这些都是实地工作的一部分，已经为威德尔海大陆斜坡过程提供了一幅独特的画面。＊＊＊

9313700 Gordon 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 principal investigator's work was the lead project in the research program and concerned the large-scale oceanographic circulation and the variability of the Weddell Sea boundary current, and how these affect and are affected by the regional water mass formation and modification processes. The Weddell Sea may be divided into three regions on the basis of the energy exchange mode. The warm regime occurs in the east where the intrusion of warm circumpolar deep water keeps the water temperature near +1 deg C. The cold regime occurs in the center, where deep water is overlain by a thick near freezing mixed layer. In both regions however enough heat is seasonally carried to the sea ice to melt it completely. In the western region, the sea ice cover does not melt, and the expected thermodynamic processes are different. Hydrographic data, coupled with the current meter observations and chemical tracer experiments, as well as turbulent flux measure- ments, and sea ice dynamics that were part of the field work have already provided a unique picture of the Weddell Sea continental slope processes. ***
