Hydrographic Observations along 20W in the North and South Atlantic Oceans

该项目提供北大西洋水文数据的收集、分析和解释。该基地由历史上的纳森瓶站、过去六年CTD数据收集的一套长线和在北大西洋和南大西洋的新的长子经段（北段将于1988年完成，南段将于1989年完成）组成。北大西洋的具体研究包括次极环流内的纬向流场、次极环流与副热带环流之间的水交换以及高纬对流的低纬影响。在南大西洋，我们的努力更具探索性，因为数据更稀少，总的目标是将我们的理解提高到与在北部发展的水平相同。

This project provides for the collection, analysis, and interpretation of North Atlantic Hydrographic data. The base if formed by a combination of historical Nasen bottle stations, a set for long lines of CTD data collection over the past six years, and new long meridional sections in the North and South Atlantic (the northern section would be done 1988 and the southern section 1989). Specific studies in the North Atlantic include the zonal flow field within the subpolar gyre, exchange of water between the subpolar and subtropical gyres, and the low latitude nfluence of high latitude convection. In the South Atlantic the endeavors are more exploratory because the data are more sparse and the general goal is to bring our understanding up to the same level that has been developed in the north.
