Fortnightly Variation of the Tsushima Warm Current on the Continental Shelf in the Southwestern Japan Sea

The first and second branches of the Tsushima Warm Current flow on the continental shelf and along the shelf break/slope in the southwestern Japan Sea, respectively. The second branch corresponds to the offshore side of the bottom temperature front between the offshore cold and nearshore warm waters. Across the Tsushima Warm Current on the continental shelf and the shelf edge, five bottom-mounted ADCPs with temperature sensors were deployed between middle June and late July 2014. At the shelf edge, the bottom temperature varied with the diurnal tidal cycle. The offshore bottom cold-water intruded into the continental shelf region in conjunction with the fortnightly spring-neap (2-week) cycle which is the modulation of the diurnal K1 and O1 internal tides. The bottom temperature front and the first branch of the Tsushima Warm Current on the continental shelf intensified in response to the bottom cold-water intrusion

長期ADCPデータによる潮流成分調和分解と対馬海峡における潮流

Since February，1997， the monitoring（six times a week）of current structure across Tsushima Straits has been being conducted using ADCP mounted to the regular Ferry boat“Camellia”measuring current velocities at every 8 m interval from sea surface to bottom. Haromonic analysis are carried out using the least square fitting to study the tidal current structure across Tsushima Straits． Estimated major eight tidal components with strong spacial valiabilities are in good agreement with those obtained by a long－term current measurements moored at the western channel
