9504258 Peterson In this project, the PIs will measure near-bottom velocities across the Argentine continental slope near 42 deg S. during 1996 and 1997. Nine moorings at nine different depths, ranging from 200m to 5200m will be deployed, using a newly-developed expendable vector-averaging current meter, with temperature and pressure sensors at a height of 50m from the bottom on each mooring. Data will be retrieved by an ARGOS transmitter released after one year's deployment. A second set of instruments will be deployed after the first year. Ship support will be provided by Dr. A. Piola and the Argentine Naval Hydrographic Service, and hydrographic surveys will be conducted during each deployment cruise. These measurements will provide reference to simultaneous hydrographic surveys in order to settle contradicting historical data about the actual strength of the Malvinas Current transport. This is a collaborative study, and in this award the PI will provide the overall scientific leadership and coordination for the project.

在这个项目中，pi将在1996年和1997年期间测量在南纬42度附近穿过阿根廷大陆斜坡的近底部速度。在9个不同深度的系泊处，从200米到5200米，将部署9个系泊，使用新开发的消耗性矢量平均流速仪，每个系泊处的温度和压力传感器位于距底部50米的高度。数据将由部署一年后发布的ARGOS发射机进行检索。第一年后将部署第二套仪器。A. Piola博士和阿根廷海军海道测量处将提供船舶支持，并在每次部署巡航期间进行海道测量。这些测量将为同时进行的水文测量提供参考，以便解决关于马尔维纳斯海流实际输送强度的相互矛盾的历史数据。这是一项合作研究，在该奖项中，PI将为该项目提供全面的科学领导和协调。
