Седиментологические Исследования Черного Моря В 91-М Рейсе Научно-Исследовательского Судна “Профессор Водяницкий”

In 2016-2017, for the first time, nearly year-long measurements of the current velocities were carried out below the thermocline at a depth of 100 m and at a depth of 1700 m that was about 100 m above the seabed by using the mooring station in the deep central part of the Black Sea. Analysis of the new data set allowed us to uncover the followings. In the near-bottom layer, the significant flow velocities were recorded, reaching a peak magnitude of 0.13 m/s. Near the frequency of 110-6 Hz, in the transition region of the energy spectrum, the spectral energy of the deep current was close to that observed in the same range in the subthermocline layer of the sea. In the range of balanced geostrophic motions, the energy spectrum had a slope of -2,8 that should be compared to a spectrum slope of -1,8 obtained for current below the thermocline. The regular strong horizontal currents were observed near the local inertial frequency fI. There was a blue shift of the inertial maximum up to 5% with respect to fI in the energy spectrum.

From 14 to 28 December 2017, in the central part of the Black Sea, within the exclusive economic zone of the Russian Federation, a joint interdepartmental comprehensive oceanological expedition was carried out on board the R/V «Professor Vodyanitsky». The main goal of the expedition was to study the characteristics of the hydrological, hydrochemical, hydro-optical and hydrobiological structure of the Black Sea waters during the winter, as well as to collect material for studying the sedimentation system of the sea, which allows assessing the particle fluxes in the water column, the rate of its sedimentation to the bottom and biogeochemical processes occurring in water and bottom sediments.
