Antarctic Circumpolar Current Choke Point Monitoring with Bottom Pressure Gauges

一种测量和监测南极绕极流输送的方法已经开发出来，并在德雷克海峡进行了试验。深压力表在电流两侧测量的压力差提供了传输的代理。这项工作将包括在澳大利亚南部和非洲南部部署一套这样的压力表。总共6个地点将在数年内进行仪器检测。来自英国的科学家将在德雷克海峡进行相关部署，以便分析南大洋周围三个阻塞点的运输变化。这些数据将有助于确定盆地间运输，这是世界海洋环流实验的一个目标。

A method of measuring and monitoring the transport of the Antarctic Circumpolar Current has been developed and tested in the Drake Passage. Differences in pressure measured by deep pressure gauges on either side of a current provide a proxy for the transport. This effort will consist of the deployment of a suite of such pressure gauges south of Australia and south of Africa. A total of 6 sites will be instrumented for several years. A related deployment will be made by scientists from the UK in Drake Passage enabling an analysis of the variations in transport at the three choke points around the Southern Ocean. These data will be useful in determining the interbasin transport, an objective of the World Ocean Circulation Experiment (WOCE).
