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

在过去的十年中，USAP船舶，RV/AS Gould和RV/IB Palmer，已经使用船体安装的声学多普勒海流剖面仪（ADCP）定期记录航行中，沿着跟踪船舶下方的速度剖面。这导致ADCP断面数据库不断扩大，特别是在西南极半岛（WAP）地区。结合其他水文数据（如XBT/ XCTD数据、漂流物轨迹、一些有限的系泊设施），该流速数据将用于进一步分析南大洋这一生态和气候敏感区域的物理环流。从这些综合数据组中可以更准确地推断出一些关键的环流特征，包括WAP陆架边缘和跨陆架迁移的年际和空间变化、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）。这项研究将支持描述性物理海洋学研究生的发展，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.
