Deep circulation in the southern Rockall Trough - the oceanographic setting of Site 610.

Abstract

Two southern sources of bottom water have a major present-day influence over the southern Feni Ridge. One source results from detachment and southward recirculation of water from a slope current, flowing northward along the west European continental margin. A second is the northward drift which occupies the deep layer of the Porcupine Abyssal Plain. Transport estimates on the overflow of Norwegian Sea Deep Water (NSDW) into the Rockall Trough suggest that NSDW probably had a lesser influence on the shaping of the Feni Ridge sediment drift, if its modern pattern and behaviour pertained through the late Neogene and Quaternary. -from Authors
