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.
