The Characteristics of the Flow Pattern at from Toyama Bay to Sado Channel by Onboard ADCP Observations

船舶搭載型ADCPで捉えた富山湾から佐渡海峡の流れの特徴

The observations using Acoustic Doppler Current Profiler (ADCP) onboard the National Institute of Technology, Toyama College training ship “Wakashio-maru” have been done from 2004. In this study, the ocean current at the area, Toyama Bay to Sado channel, had been measured and analyzed for the characteristics. The authors also compared these ADCP observations with a numerical simulation results and satellite remote sensing data for chlorophyll-a concentration. ADCP data is only around ship’s track. So, with comparing these data, it would be able to know the situation of wide area. By the observations at summer seasons of 2014 and 2015, the authors have observed the main path of “Tsushima Warm Current” are flowing into Sado Channel, which the direction from North to NE and the speed about 0.6~0.8ms-1. And, between Noto peninsula and Sado island, an eddy or U shape curve current was observed.
