Winter Chlorophyll Bloom along the Northern Coast of Borneo:Observation and Dynamics
Chlorophyll-a (Chl-a) concentration in the southern South China Sea (SCS) has significant spatio-temporal variations.Analysis of recent remote sensing data reveals a seasonal Chlorophyll bloom along the northern coast of Borneo during boreal winter.To quantitatively describe the phenomenon and identify its underlying physics,we study an ensemble of satellite products including ocean color,surface wind and precipitation in the region.Correlation calculation based these measurements show that river discharge in the northern Borneo peaks in winter and induces a wide coastal productive zone,with monsoon-driven Ekman flows providing favorable condition for the offshore advection of high Chl-a concentration.The interannual occurrence of winter Chlorophyll bloom is found to be anti-correlated with the El Ni?o-Southern Oscillation (ENSO).During 1998-2010,Chl-a concentration near the northern coast of Borneo tends to be low (high) in El Ni?o (La Ni?a) winter.
