Seasonal anomalies of water salinity in the Gelendzhik region of the Black Sea according to shipborne monitoring data

Аннотация

The paper presents results of analyzing the data on the variability of salinity in the upper layer of the coastal zone (including the seasonal thermocline) of the Black Sea during the 2010–2013 warm seasons (April–November). The data for the analysis were obtained from the regularly conducted CTD probing the by R/V Ashamba on a cross section abeam the Golubaya Bay (Gelendzhik). The relationship between salinity anomalies, coastal precipitation, and wind forcing is analyzed. It is shown that the contribution of thermal stratification to the density stratification in the seasonal thermocline is almost always greater than the contribution of salinity stratification, and the ratio of the former to the latter increases from April to November.
