Spatial distributions of thermohaline structure and phytoplankton biomass in the east China Sea during early summer

We were carried out on the thermohaline structure and phytoplankton biomass, such as chlorophyll a in the East China Sea during early summer in 2001. As a results of water mass on T-S diagram, three characteristic water mass were identified. We are divide them into coastal water mass, cold water mass and oceanic water mass. The former are characterized by high temperature, low salinity and high Chl-a concentration originated China territory, the secondary are characterized by low temperature, high density and high Chl- a concentration originated bottom cold water of Yellow Sea, and the latter are high temperature, high salinity and low Chl-a concentration originated from Tsushima warm current, between them internal discontinuous layer was formed at the intermediate depth (about 20 ~30m and 45m layer). Phytoplankton biomass, such as chlorophyll a concentration in the East China Sea were controlled by the coastal waters of Chinese Continent.
