Abstract

Abstract

Samples for seawater nutrients and chlorophyll a were collected in the western South China Sea from 31 August to 26 September,2014. Results show that coast of IndoChina have cold-core eddy with low temperature,high salinity and warm-core eddy with high temperature,low salinity which is located in the lower right relative to cold-core eddy. Relative to warm-core eddy and other areas,nutrients of cold-core eddy have higher concentration,50 m,75 m and 100 m layer of which is increased remarkably. DIP higher by 0.21 μmol/L,0.39 μmol/L and 0.23 μmol/L respectively,DIN higher by 4.94 μmol/L,7.56 μmol/L and 3.76 μmol/L respectively,and DSi higher by 2.55 μmol/L,5.25 μmol/L and 3.46 μmol/L respectively. It indicates cold-core eddy on improving primary production with significant nutritional advantages and huge potential. DCM layer appear in 50 m layer,maximum value of which is located in coast of Hainan island. Under the influence of nutrients,cold-core eddy increases primary productivity significantly in 25 m layer,while value of Chl a is not high in 75m,100m layer,which may be caused by low temperature with cold-core eddy.
