Abstract

This work was aimed at estimation of an input of small and medium rivers of Sochi-Adler area into the standing stock of dissolved organic carbon (DOC) in the coastal zone of the Black Sea. Presented data were acquired in May 2011 and May 2012 in the coastal region of the Greater Sochi. Studied area included river mouths of the Mzymta, Kudepsta, Sochi and Bitkha rivers, where mean DOC concentrations were 69.22 μM, 174.33 μM, 171.04 μM and 4678.31 μM respectively, while the background seawater concentration of the DOC (two kilometers away from the river mouth) was about 220 μM. The Mzymta, Kudepsta, Sochi and Bitkha rivers significantly differ in chemical composition, including the amount of carried organic matter, mainly due to the difference in height of their water-producing areas, different contribution of feeding sources and different anthropogenic impact.
