Summary:— We present the results of optical studies of organic matter in the surface water layer of Gelendzhik Bay and adjacent areas of the Black Sea. The efficiency of remote laser sensing for determining the relevant grid of sampling stations is shown. A weak contribution of terrigenous dissolved organic matter (DOM) has been established. A slight increase in the concentration of humic substances was demonstrated near the mouth of the Su-Aran River. The maximal content of biolabile DOM is typical for coastal regions in Gelendzhik Bay. In the eastern part of the bay high levels of DOM, particulate organic matter (POM), as well as the maximum content of DOM and POM together, were observed on the basis of fluorescent lidar data.
