Abstract : Subsurface current measurements made south of Plantagenet Bank, Bermuda, indicated a steady mean current field over a two week period during July 1961, flowing approximately in a westerly direction. Measurements were made using drogues, free instruments, and hydrographic stations. The use of the free instrument, a device for measuring horizontal water transport by sinking to a predetermined depth and returning to the surface, is described. A region of laminar flow was indicated up current and around the edges of the bank, and a turbulent region was found to exist just down current of the bank edge. Surface currents of about 25-35 cm/sec. were found, while with increasing depth there was a gradual decrease in velocity, the mean velocity being 10-12 cm/sec. between 600 fathoms and the bottom.
