Speeds as high as 44 centimeters per second were observed 200 meters above the ocean bottom under the Gulf Stream at 70°W longitude and were associated with time-dependent motion that had a speed range of 40 centimeters per second and a time scale of about 30 days. These deep current fluctuations appear to be coupled with fluctuations in the surface position of the Stream and with surface and bottom current fluctuations 200 kilometers to the north.
