Observation of Direction and Speed at Tsushima Current by Shipboard ADCP

Abstract

Tsushima Warm Current is running at Japan Sea form South to North. We observed its current direction and speed at the north region of Noto peninsula by the shipboard ADCP. The observations were acted at two times, which are summer season of 2004 and 2005. From these observations, the main flows of the currents are steady, which directions are almost along to the coast and the speeds are almost 50-80cm/s. Also, at the shadow area of the peninsula for the main flow, the disturbed flows are observed.
