AbstractThe Bohai Sea is a semi-enclosed inland sea with case-2 waters near the coast.A comprehensive set of optical data was collected during three cruisesin June, August, and September 2005 in the Bohai Sea. The vertical profile measurements,such as chlorophyll concentration,water turbidity, downwelling irradiance, and diffuse attenuation coefficient,showed that theBohai Sea was vertically stratified with a relative clear upper layer superimposed on a turbid lower layer.The upper layer was found to correspond to the euphotic zone and the deep chlorophyll maximum(DCM) occurs at the base of this layer. By tuning a semi-analytical model(Lee etal.,1998,1999) for the Bohai Sea,we developed a method to derive water inherent optical properties and the depth of DCM from above-surface measurements. Assuming a‘fake’bottom in the stratified water,this new method retrieves the‘fake'bottom depth,which is highly correlated with the DCM depth.The average relative error between derived and measured values is 33.9% for phytoplankton absorption at 440nm, 25.6% for colored detrital matter (detritus plus gelbstoff) absorption at 440nm, and 24.2% for the DCM depth.This modified method can retrieve water inherent optical properties and monitor the depth of DCM in the Bohai Sea, and the method is also applicable to others tratified waters.
