Spatial and temporal variability in stocks and biochemical composition of dissolved and particulate organic matter (OM) in the Black sea shelf waters. Rates of the OM oxidation in the Caucasian shelf waters of the Black Sea increase in autumn leading to decline in the OM stocks by 1,5-3 times compared to summer both in the surface, and the bottom layers. Average period of the phosphate turnover is 10-20 h along the entire studied coastal area; thus, the phosphate recycling provides for intensive primary production of OM in summer. Owing to the active protease, coastal ecosystems utilize all the available protein during one day.
