Abstract
Current meters were placed approximately 2 meters off the bottom at depths from 2900 to 5000 meters on the continental rise near the New England seamount chain. Current velocities greater than 15 cm/sec were recorded in a west-southwest direction, parallel to the regional contours. The greatest velocity recorded was 26.5 cm/sec toward the southwest. Spectrum analyses of the time-series curves have resolved periodic motions superimposed on secular, contour-following trends. An interaction between the contour current and the Gulf Stream is also apparent. These data suggest that the contour current, a Western Boundary Undercurrent, is competent to transport and erode continental rise sediments. A significant sediment dispersal system parallel to the regional slope is confirmed to be operative on the present-day continental rise.
