Decadal variability of chlorophyll a in the South China Sea： a possible mechanism
Four climatologies on a monthly scale （January, April, May and November） of chlorophyll a within the South China Sea （SCS） were calculated using a Coastal Zone Color Scanner （CZCS） （1979-1983） and the Sea-viewing Wide Field-of-view Sensor （SeaWiFS） （1998-2002）. We analyzed decadal variability of chl...

| description | Four climatologies on a monthly scale （January, April, May and November） of chlorophyll a within the South China Sea （SCS） were calculated using a Coastal Zone Color Scanner （CZCS） （1979-1983） and the Sea-viewing Wide Field-of-view Sensor （SeaWiFS） （1998-2002）. We analyzed decadal variability of chlorophyll a by comparing the products of the two observation periods. The relationships of variability in chlorophyll a with sea surface wind speed （SSW）, sea surface temperature （SST）, wind stress （WS）, and mixed layer depth （MLD） were determined. The results indicate that there is obvious chlorophyll a decadal variability in the SCS. The decadal chlorophyll a presents distinct seasonal variability in characteristics, which may be as a result of various different dynamic processes. The negative chlorophyll a concentration anomaly in January was associated with the warming of SST and a shallower MLD. Generally, there were higher chlorophyll a concentrations in spring during the SeaWiFS period compared with the CZCS period. However, the chlorophyll a concentration exhibits some regional differences during this season, leading to an explanation being difficult. The deepened MLD may have contributed to the positive chlorophyll a concentration anomalies from the northwestern Luzon Island to the northeastern region of Vietnam during April and May. The increases of chlorophyll a concentration in northwestern Borneo during May may be because the stronger SSW and higher WS produce a deeper mixed layer and convective mixing, leading to high levels of nutrient concentrations. The higher chlorophyll a off southeastern Vietnam may be associated with the advective transport of the colder water extending from the Karimata Strait to southeastern Vietnam. |
