Collaborative Research: Southern Ocean Current Observations from the U. S. Antarctic Research Vessels

这项拟议的工作涉及美国南极计划运营的RVIB Nathaniel B. Palmer和研究船Laurence M. Gould上的船载声学多普勒电流剖面仪（ADCP）计划的开发和维护。目标是在一个采样稀少的偏远地区生成一套质量可控的上层海流速度数据集，但它在全球海洋环流中起着重要作用。进一步的目标是制定正在进行的数据收集计划，使其能够以最少的人员和资源进行维护，并及时向公众提供观测结果。长期的科学目标是测量德雷克海峡内上层洋流的季节和年际变化，将这些信息与类似的温度观测相结合，研究热交换的变化，并在各种时间和空间尺度上表征南大洋的速度结构。

This proposed work concerns the development and maintenance of a shipboard acoustic Doppler current profiler (ADCP) program on board the RVIB Nathaniel B. Palmer and the research vessel Laurence M. Gould, operated by the United States Antarctic Program. The objective is to generate a quality-controlled data set on upper ocean current velocities in a sparsely sampled and remote region, yet one that plays an important role in the global ocean circulation. Further goals are to develop the underway data collection program so that it can be maintained with a minimum of personnel and resources, and that the observations become publicly available in a timely manner. Long-term science objectives are to measure the seasonal and interannual variability of upper ocean currents within the Drake Passage, to combine this information with similar temperature observations to study the variability in the heat exchange, and to characterize the velocity structure in the Southern Ocean on a variety of time and space scales.
