US-France Cooperative Research: Program to Study the Southwestern Atlantic

该奖项将支持哥伦比亚大学Lamont-Doherty地质天文台Silvia Garzoli博士与法国巴黎皮埃尔大学海洋和气候实验室Christine Provost博士在物理海洋学方面的合作研究。该项目的目标是分析巴西和马尔维纳斯洋流汇合区的国际高分辨率研究数据。美国、法国和阿根廷为研究西南大西洋的动态而进行的大规模国际努力将于1990年初完成。该方案包括密集的实地工作，主要是部署一大批仪器(反向回声测深仪和海流计系泊设备)，为期18个月，收集为期两年的红外卫星图像，以及实现三次水文/营养物质广泛调查。这项研究将产生一套共同收集的、有价值的和广泛的海洋数据，可用于校准、减少和分析。这项奖励将为Garzoli博士访问法国提供资金，目的是建立共同数据校准标准。这将有助于对西南大西洋的整个环流和温盐变化系统进行联合数据分析和随后的联合科学解释。

This award will support collaborative research in physical oceanography between Dr. Silvia Garzoli, Lamont-Doherty Geological Observatory of Columbia University and Dr. Christine Provost, Laboratory of Oceanography and Climate, University of Pierre and Marie Curie, Paris, France. The objective of the project is to analyze data from an international high resolution study of the confluence zones of the Brazil and Malvinas currents. A large international effort by the US, France and Argentina to study the dynamics of the Southwestern Atlantic will be completed by early 1990. The program consists of intensive field work based primarily on the deployment of a large array of instruments (inverted echo sounders and current meter moorings) for a period of 18 months, the collection of infrared satellite images for a period of two years, and the realization of three hydro- graphic/nutrients extensive surveys. The study will result in a jointly-collected, valuable and extensive set of oceanographic data available for calibration, reduction, and analysis. This award will provide funds for Dr. Garzoli to visit France for the purpose of establishing standards for common data calibration. This will facilitate the joint data analysis and consequent joint scientific interpretation of the whole system of circulation and thermohaline variability in the Southwestern Atlantic.
