This work is the continuation of a joint project with the Polar Research Institute of China to make measurements of the structure of the upper ocean in the northern Weddell Sea along the route taken by the PRI's antarctic supply vessel, R/V Xue Long. The observations, obtained from expendable instruments, complement existing hydrographic observations along various transects through the northwestern Weddell Sea region and data from moored current meter arrays in the Weddell-Scotia confluence zone. This effort builds upon a successful series of expendable bathythermographs and conductivity-temperature-depth probes obtained by the science party on board the R/V Xue Long in the 1998 pilot phase of this project.The west-to-east transit of the Weddell Sea by the ship makes it possible to obtain a series of ocean soundings that are otherwise unobtainable. The information is particularly important because it has been shown that the Indian Ocean sector is an anomalous region with respect to connections between antarctic and lower latitude climatic features and indices. In the pilot program the necessary data acquisition system, both software and hardware, were installed in the ship and an excellent working relationship with Chinese antarctic scientists was developed.

这项工作是与中国极地研究所联合项目的延续，该项目旨在沿着 PRI 的南极补给船雪龙号的路线测量威德尔海北部上层海洋的结构。 这些观测结果是通过消耗性仪器获得的，补充了威德尔海西北部地区各断面沿线的现有水文观测数据以及威德尔-斯科舍交汇区系泊海流计阵列的数据。 这项工作建立在1998年该项目试验阶段的科学小组在雪龙号R/V上成功获得一系列一次性深海温度计和电导率-温度深度探测器的基础上。该船从西向东穿越威德尔海使得获得一系列其他方式无法获得的海洋探测成为可能。 这些信息特别重要，因为事实表明，就南极和低纬度气候特征和指数之间的联系而言，印度洋区域是一个异常区域。在试点项目中，船上安装了必要的数据采集系统（包括软件和硬件），并与中国南极科学家建立了良好的合作关系。
