U.S./Chinese Ship of Opportunity Sampling Program

这项工作是与中国极地研究所联合项目的继续，该项目旨在测量沿着PRI的南极补给船R/V雪龙号所走路线的威德尔海北方上层海洋结构。 观测，从消耗性仪器，补充现有的水文观测沿着通过威德尔海西北部地区的各种断面和数据从系泊海流计阵列在威德尔-斯科舍汇合区。 这项工作是在1998年该项目试验阶段科学考察队在“雪龙”号上成功获得的一系列一次性使用的深海温度计和电导率-温度-深度探测器的基础上进行的。“雪龙”号由西向东穿越威德尔海，使人们有可能获得一系列其他方法无法获得的海洋探测结果。 这些资料特别重要，因为已经表明，印度洋部分在南极和低纬度气候特征和指数之间的联系方面是一个异常区域。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，并与中国考古科学家建立了良好的工作关系。

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.
