Exceptionally Strong Near-Bottom Flows on the Continental Rise of Nova Scotia

Recent current velocity measurements across the lower continental rise of Nova Scotia show a deep equatorward flow with speeds (maximum, 73 centimeters per second) among the highest recorded for the deep sea. Silicate measurements indicate that this flow usually consists of southern-source (Antarcti...

Description
Summary:Recent current velocity measurements across the lower continental rise of Nova Scotia show a deep equatorward flow with speeds (maximum, 73 centimeters per second) among the highest recorded for the deep sea. Silicate measurements indicate that this flow usually consists of southern-source (Antarctic) bottom water. These measurements confirm the existence of a second and deeper western boundary flow that was earlier inferred from geological observations.
