Аннотация:The results of the long-term experimental works in the shelf zone of the Black Sea near Gelendzhik in 2011-2014 are presented. The experimental works were performed synchronously with satellite observation. Subsatellite measurements were conducted from a boat equipped with an ADCP, a CTD probe and a meteorological station.
The formation and drift of a near-shore anticyclonic eddy of 20 km in diameter as well as submesoscale eddies of 5-7 km in diameter were observed. The currents induced by those eddies in the shelf zone were measured. The eddy structures detected by SAR were identified in ADCP current data and their impact through the water depth was traced. The focus was on filamentary slick bands involved into small scale vortical processes and allowing estimation of spatial characteristics of submesoscale eddies based on their SAR signatures.
Torrential rains that took place in the course of the experimental works provoked an intense outflow of polluted waters into the sea. Satellite remote sensing data in microwave and visible ranges of the electromagnetic spectrum have allowed not only to identify the waters polluted by the muddy river runoff and emergency discharges of municipal sewage facilities and to quantify the concentration of suspended substances, but also to trace the influence of submesoscale eddies on the spread of pollution in the coastal zone.
