Capabilities of the oceanological examination system of satellite monitoring of the Azov-Black Sea region on the example of 1993
The lack of environmental information caused by drastic decrease in number of Ukrainian research expeditions in the Azov and Black Seas could be partly compensated by TV information and data on the sea surface temperature (SST) from satellite. The previously established relationships between the SST and water dynamics, atmospheric transport and biotic and fisheries indices make it possible to provide estimates, of the state of ecosystem and fisheries conditions in the region in 1993. The winter of 1992-1993 was abnormally cold. During the winter months, SST was everywhere below the normal. The south-western region remained the coldest until mid-May. Conversely, that region became the warmest in June. During July and August the SST field was fairly uniform throughout the Sea of Azov, with recurrent appearance of warmer water spots, likely to be caused by local blooms and weakened water dynamics in different parts of the sea. The main feature of the temperature regime of the sea is a high thermal inertia of its western part. In the autumn it is slow to cool and in the spring it is slow to warm up. This may influence the spring and autumn migration patterns of the anchovy (Engraulis encrasicolus). During the first cold spell from 19 to 29 September, the sea water temperature fell by 5-6.5 degree C (from 21-22 degree C to 14-16.5 degree C) which probably triggered schooling of the anchovy and its migration from Azov to Black Sea. Fishing for migrating schools of this species started on 8 October.
