Paper Abstract

Using data obtained in Canarian Upwelling, Black and Marmora Seas from board research ships of Shirshov Institute of Oceanology RAS the possibility of 'yellow substance' concentration determination in productive and polluted waters by one of the four optical methods was shown. The first method is based on the contact measurements of the vertical light attenuation coefficient at 500 nm with descending devices. The second method uses remote measurements of the sea-water radiance coefficient spectra from board a moving ship with three-channel spectrophotometer. The water type optical index is calculated from the obtained sea water radiance spectrum, then using the appropriate classification the main natural admixtures concentrations are estimated. According to the third method 'yellow substance' concentration is estimated from the measurements of sea water fluorescence intensity in blue-green spectral band (approximately 440 nm) by laser remote sensing of water surface in UV. The results of 'yellow substance' concentration estimation in sea water by these three methods were proved by the comparison with the concentration measurements data obtained by the two-ray laboratory photometer in filtrated samples of sea water taken at the stations.
