Shelf-Edge Circulation on the West Antarctic Peninsula from Archived ADCP Data: Follow-on Analyses

在过去的十年中，USAP的RV/AS Gould和RV/IB Palmer船使用船体安装的声学多普勒电流剖面仪（ADCP）常规记录航行中，沿着船下的航迹速度剖面。这导致了ADCP样带数据库的不断增长，特别是在南极半岛西部（WAP）地区。结合其他水文数据（例如XBT/ XCTD数据、漂浮物轨迹、一些有限系泊），目前的速度数据将用于进一步分析南大洋这个生态和气候敏感区域的物理环流。大陆架边缘和跨大陆架运输的年际和空间变率、潮汐的影响、环流对海冰形成的控制以及相关的南极生态系统（如磷虾）等过程是一些关键的环流特征，可以从这些综合数据集中更准确地推断出来。本研究将支持研究生在描述物理海洋学方面的发展，并向本科生介绍定量科学分析。

Over the past decade the USAP ships, RV/AS Gould and RV/IB Palmer, have used hull-mounted acoustic Doppler current profilers (ADCP) to routinely record underway, along track velocity profiles beneath the ships. This has resulted in a growing database of ADCP transects, especially in the region of the West Antarctic Peninsula (WAP). Combined with other hydrographic data (e.g. XBT/ XCTD data, drifter tracks, some limited moorings) this current velocity data will be used for further analysis of the physical circulation in this ecologically and climatically sensitive region of the Southern Ocean. Processes including inter-annual and spatial variability of WAP shelf-edge and cross-shelf transport, the effects of tides, circulation controls upon sea-ice formation and associated Antarctic ecosystems (e.g. krill) are some of the key circulation features that may be more accurately inferred from these combined data sets. This study will support the development of a graduate student in descriptive physical oceanography, and introduce undergraduate students to quantitative scientific analysis.
