| Abstract: | Until recently,optical processes in shallow water,where the sea bottom is shallow enough to be optically detected,has received little attention outside of a relatively small number of modeling and remote sensing investigations.The contribution from the bottom of optical shallow water changes the intensity and spectral distribution of remotely sensed signal above water surface,which became one of the key problems for water quality remote sensing inversion accuracy.In shallow water,where the depth is much les... |
