Current studies off Plantagenet Bank

Abstract

A series of current measurements were made southwest of Plantagenet Bank. Bermuda from October 5-18, 1959, at various depths ranging from 5 fathoms to the bottom in water depths of from 40 to over 1000 fathoms. With the exception of the bottom measurements which were made with a camera type current meter, all the current measurements were made with parachute drogues. The magnitude of the currents ranged from 1 knot at 5 fathoms to less than 0.02 knot just off the bottom and the direction of flow was generally southeast. The somewhat erratic behavior in the movement of the drogues just south of the bank seemed to indicate turbulent flow in this region. The currents do not seem to be tidal in nature, but during the period of measurement flowed fairly consistently in one direction. perhaps indicating association with the Gulf Stream.
