The present work is devoted to investigation of propagation of suspended matter by the action of storm winds of the west coast of the Crimea Peninsular in the Black Sea. Scenes with observed intense fluxes of suspended matter that was caused by the action of extreme storm wind were selected from the Landsat 4, 5, 7, 8 data archive for the 1983-2014 period. All scenes were divided corresponding to storm wind directions: the southern, northern and western winds. It is shown that the northern storms induce formation of intense alongshore currents, which carry the suspended matter in the southern direction, followed by its removal to the deep sea. Under the action of the southern storms turbid waters move north and are mainly concentrated in the region of the Kalamitsky bay. Strong westerly winds lead to the emergence of upwelling of the west coast of Crimea. At the periphery of the upwelling, filament and cyclonic eddies are formed, that carry the suspended matter from the coast in the direction opposite to the wind.
Keywords: suspended matter, Landsat, submesoscale dynamics, coastal erosion, the Black Sea
