Estimation of the ecological state of shelf waters or inland seas needs to obtain detailed data over the area operatively. The new three-channel passive optical complex for ecological monitoring of marine aquatoria (EMMA), developed by us, gives the sea radiance coefficient spectra from board a moving ship. For processing of the data of measurements aiming at the water admixtures concentration assessment an original method for solving of the inverse problem is used, which is based on the intrinsic properties of the pure water absorption spectrum — water absorption step method (WASM). Complex EMMA together with the program WASM was applied for studying of the areas of different sea water types mixing in the Black Sea. Giving data at the spacial resolution of 3 meters from board a moving vessel, it enabled us to get the detailed distribution of the natural water constituents over the two coastal regions of the Black Sea with different trophicity under exploration. The obtained remote sensing data were verified with the results of measurements carried out at the stations.
