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.

这项拟议的工作涉及的发展和维护的船载声学多普勒海流剖面仪（ADCP）程序上的RVI B纳撒尼尔B。帕尔默和研究船劳伦斯M。古尔德号由美国南极计划运营。 其目的是在采样稀少的偏远区域生成一套质量可控的上层洋流速度数据，但这套数据在全球海洋环流中发挥重要作用。 进一步的目标是制定正在进行的数据收集计划，以便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。 长期科学目标是测量德雷克海峡内上层洋流的季节性和年际变化，将这一信息与类似的温度观测结果联合收割机结合起来，研究热交换的变化，并在各种时间和空间尺度上描述南大洋的速度结构。
