Abstract
On the base of series expeditions, carried out by the Marine Hydrophysical Institute (Sevastopol) and the Southern Research Institute of Marine Fisheries and Oceanography (Kerch) in 2002–2015, regression equation with close inverse relation between salinity and concentration of colored dissolved organic matter in the coastal Azov Sea waters is received. Using this equation on average monthly salinity schemes the seasonal fields of colored dissolved organic matter content are calculated and the first submissions of their structure in the investigated water areas are formed. It is shown that in the northern and eastern shores of the sea the studied field contain a significant component which stipulated by the river runoff. This component is completely transformed on the stock fronts of the rivers flowing into the sea. Seaward of the fronts in the central, western and southern regions of the Azov Sea, the dissolved organic matter field is homogeneous.
