Optical characteristic and particle composition in China Yellow Sea and East China Sea

The marine waters of the Yellow, Sea and East China Sea cover a large area and represent an important fishing ground. Monitoring changes in their biological productivity is an important goal that can hopefully be reached using satellite remote-sensing. Operational ocean color satellite algorithms are generally successful over the open ocean. These algorithms are based upon simple band ratios, assuming that the only optically active component of any significance in the water is phytoplankton. While this assumption generally holds for the open ocean waters, it may not always be the case for coastal ecosystems (in what are commonly referred to as Case 11 waters). This problem is particularly evident in the study site. For the high concentration of SPM, it make the failure of the atmospheric correction algorithm and decrease the accuracy of the products of ocean color remote sensing, such as the SeaWiFS and MODIS. In order to develop the high accuracy regional algorithm, the inherent optical properties in Yellow Sea and East China Sea must study previously. In this paper, the absorption and scattering properties of the optically significant biogeochemical variables and the composition of SPM are studied use the in situ dataset of the inherent optical properties in the Yellow Sea and East China Sea.
