Popov M. Oceanographic characteristics of Balaklava bay, the assessment of pollution of its waters and the adjacent waters of the Black Sea

In dissertation study physical and geographical conditions, climate features of Balaklava Bay and adjacent waters of the Black Sea water were examined. The geomorphological description of coasts was present. Мorphometric investigations of the bay and adjacent waters were realized. For the first time fields of major oceanographic elements were discussed in detail. There was appreciated the current level of pollution compared to adjacent the Black Sea waters. On the basis of arrays of contact and satellite observations and results of numerical simulation for the first time patterns of local system of flows, structure and variability of termohaline field, fields of basic hydrochemical elements were identified. Separately it was considered physical nature of different types of coastal upwelling, its importance for the bay ecosystem was evaluated on the quantitative level. The current level of pollution of investigated area was analyzed. In addition to classic hydrochemical methods there were used hydrooptical probe observations. It was possible to identify the sources of pollution, to assess pollutant concentrations and to identify ways of distribution. For the first time, there was local subpopulation of mussels selected as a bio-indicator which reflects the degree of anthropogenic impact in different parts of the bay. It is shown in waters with high pollution (corner and south-eastern parts of the Balaklava Bay) mussel has deviations of some biological and physiological parameters.
