Description

Hydrographic condition around Futaoi Island in eastern channel of Tsushima Straits was not only changed by seasonal thermohalocline and mixed layer depth but also strongly influenced by coastal water distribution depending on local precipitation and spread of Changjiang diluted water from Chinese continent through Tsushima Straits. Chlorophyll a concentrations were high in the coastal water with nearshore low salinity but were low in the Changjiang diluted water with offshore low salinity. Subsurface chlorophyll a maximums were found corresponding to the thermohalocline which depended on the distributions and thicknesses of Changjiang diluted and coastal waters.
