9416889 Peterson This project proposes analysis of data from bottom pressure gauges deployed across chokepoints for the Southern ocean flow. The deployment of the instruments was funded under a previous grant. Bottom pressure gauges were deployed between South Africa and the Antarctic coast close to the Greenwich Meridian and at two locations spanning the Antarctic Circumpolar Current (ACC) south of Tasmania. Simultaneously, the British deployed similar instruments in the drake Passage. The main scientific goal of these deployments was to determine the fluctuations in transport of the Antarctic Circumpolar Current, relate it to those in the subtropical and subpolar gyres and to the wind field over the southern oceans.

9416889 Peterson 该项目建议对部署在南部洋流阻塞点的底部压力计的数据进行分析。 这些工具的部署是由先前的赠款资助的。 底部压力计部署在南非和格林威治子午线附近的南极海岸之间以及塔斯马尼亚以南跨越南极绕极流（ACC）的两个地点。 与此同时，英国人在德雷克海峡部署了类似的仪器。 这些部署的主要科学目标是确定南极绕极流输送的波动，将其与副热带和副极地环流以及南部海洋上的风场联系起来。
