Abstract
The investigation of thermohaline structure of water near the Crimea coast and the adjacent open water area of the Black Sea in July 2016 are presented based on data received in 87th cruise of the research vessel "Professor Vodyanitsky". It is shown that abnormal temperature growth was observed near the Crimean coast, due to interannual variations. It was revealed that in the Sevastopol and Crimean anticyclones temperature was increased and salinity was decreased, while the Sevastopol anticyclone appeared below the cold intermediate layer, and the Crimean anticyclone appeared in the upper quasihomogeneous layer. The maximum depth of the cold intermediate layer core were traced along the Crimean coast and in the north-west area of the survey, the minimum values were in the south area closer to large-scale cyclonic cycles of the Black Sea. The level of connection between the horizontal fields of temperature and salinity is estimated as a function of depth. It is shown that a high bond of thermohaline fields was observed under the main halocline and below the cold intermediate layer at 150-350 m depths.
