The multi-mission altimeter data for the Sea Level Anomaly (SLA), processed and distributed by Copernicus Marine Environment Monitoring Service, and the meteorological reanalisys of ECMWF ERA-Interim data are used to compare the seasonal variability of the Black Sea circulation and the atmosphere circulation above the basin. The seasonal averaged maps of the SLA, geostrophic current anomaly, mean sea level pressure, the wind velocity and curl reveal an accordance between the rotation of the atmosphere and sea circulation in the Eastern Black Sea area. The winter positive wind curl area, centered over the inner part of the basin, explains the winter intensification of the Rim Current. The summer configuration of wind curl could explain the spring-summer intensification of the Batumy anticyclonic eddy and the negative SLA near the Caucasus coast.

The oil products remain the main contaminant of the Black Sea, as well as of the entire world’s oceans. A main amount of oil is transported by tankers and reloaded in port terminals. 12 per cent of overall marine pollution is the share of transportation, oil congestion and accidents losses. At the Caspian-Black Sea-Mediterranean area there are actively used the Black Sea ports of Batumi, Poti and Kulevi.
A huge damage to the nature is doing by oil spills on the surface of the oceans and seas owing to transportation oil by tankers. These spills are associated with loading and unloading operations as well as with tankers accidents. In this case, the oil spreads as a spot on the surface of the sea.

Problems associated with environmental pollution from the oil spill in the sea, made necessity to develop mathematical models that describe the transportation and transformation processes of oil spills. The proposed mathematical model can be used for prediction of the spread of an oil spill during the process of spreading of oil products on the water surface, and it also enables to take into account the reduction of the area of spill due to the action of sea-surface winds and turbulence of the water surface.
