Abstract
THE pronounced seaward dip of near bottom isotherms which is frequently observed on the continental rise off eastern North America suggested that a deep bottom current flows south along the western side of the North Atlantic1. Near bottom velocities of 5 to 18 cm/s were subsequently measured in this southerly flowing Western Boundary Undercurrent east and south-east of Cape Hatteras, east of Cape Cod, and off Greenland and Labrador2. These measured velocities are competent to transport all the sizes of sediment generally found on the continental rise3.
