ABSTRACT 0084700Four hydrographic sections straddling the deep western boundary current in the tropical North Atlantic will be made in an effortto locate a rapidly propagating pulse of Labrador Sea watertraveling down the western boundary of the Atlantic. This transient was generated when Labrador Sea water productionintensified in the late 1980's. The objective is to obtaina quantitative estimate of the speed with which the deep oceanconveys information about climate anomalies in high latitudes tothe tropics.

摘要 0084700四个水文剖面横跨热带北大西洋西部边界流深处，将努力定位拉布拉多海水沿大西洋西部边界快速传播的脉冲。 这种瞬变是在20世纪80年代后期拉布拉多海水生产加剧时产生的。 目的是定量估计深海向热带传递高纬度气候异常信息的速度。
