A vertical profile of currents near Plantagenet Bank
Abstract
A vertical profile of currents on the southern slope of Plantagenet Bank southwest of Bermuda is obtained by tracking acoustically a slowly sinking float. It is found that the Bank has a pronounced influence on the local flow. At depths less than 500 m the currents are swift at more than 30 cm/sec whereas at this depth transition to aslow drift of the deep water along the topography is observed. Changes in horizontal velocities with depth are not gradual but occur in regions of limited vertical extent where velocity differences of 10-20 cm/sec in 10 m were observed. The effective blocking of the deep water by the Bank caused a local depression of the main thermocline deeper than in typical for the Bermuda area.
