Abstract

The annual dynamics of the decomposition rate, standing stock, and residence time of labile organic matter as an index of full self-purification were investigated in Novorossiisk Bay, Black Sea. The results are suggestive of fairly effective processes of biological self-purification in polluted waters of the bay. The decomposition rate was highest (0.3 – 0.7 mgO2 /l per day) during the summer, and it decreased by 4 – 8 times in winter. The residence time of labile organic matter was 97 –104 days in winter and 8 –11 days in summer. Oxygen consumption rates measured in different areas of the bay conformed to their trophic status and were not above the normal level for summer.
