For better resolution of bottom processes in the bottom density flow model, the computational domain is split vertically into bottom and overlying areas. In the lower region with a thickness of 20 m, the vertical grid spacing is 1 m. The basic equations of the model are transformed for each of the regions using σ-coordinate. According to the simulation results, the features of the distribution of North Sea water are highlighted, as well as the associated change in the salinity field in the overlying layer. Estimates of the possible influence of runoff currents on the distribution of North Sea waters are obtained.","PeriodicalId":169855,"journal":{"name":"DEDICATED TO THE 90TH ANNIVERSARY OF PROF. K.N.

Fedorov. The symposium was held at the Shirshov Institute of Oceanology from October 30 to November 2, 2018. The main objectives of the symposium were to attract the attention of mature and young researchers to the study of mesoscale and submesoscale processes in the hydrosphere and atmosphere of the Earth, and to give a new incentive to study this important area of knowledge. The participants of the symposium (about 260 people) presented 120 reports in various areas of modern oceanological research, see the article (Zatsepin, Ginzburg et al., 2018) and (Proceedings..., 2018).\u0000Even before the symposium, its Program and Scientific Committees decided to publish selected articles of its participants in a special issue of the Journal of Oceanological Research. A corresponding announcement was made, to which many of the participants in MSP-2018 symposium responded with the presentation of their articles. These articles form the basis of the contents of this issue of the Journal.\u0000It contains 20 scientific articles written by the participants of the symposium, covering the results of studies of various phenomena and processes, such as: the general circulation of water in the ocean and its mechanisms, eddies, jets and fronts in the oceans and seas, thermohaline structure and its variability, small-scale interaction of the ocean and atmosphere, bottom and intermediate layers, etc. These processes and phenomena were studied in various basins using traditional and new methods of field research, satellite information, laboratory, numerical and theoretical modeling. New results have been obtained that clarify existing ideas about the dynamics and hydrological structure of the ocean and seas, about the processes of interaction between the ocean and the atmosphere.\u0000The editors of this issue of the Journal of Oceanological Research express the hope that the articles contained in it will attract the attention of a wide range of readers.","PeriodicalId":169855,"journal":{"name":"DEDICATED TO THE 90TH ANNIVERSARY OF PROF.

To study this mechanism, several automatic measuring stations were installed at the bottom of the shelf-continental slope zone in the depth range from 80 to 243 m, on the cross-section abeam of the Gelendzhik Bay. The observations that lasted for 1.5–2 months were fulfilled during two periods in the beginning and the end of 2018. The stations were registering hydrophysical (temperature, salinity, pressure and current velocity) and hydrochemical (dissolved oxygen concentration) parameters at a 0.5–2.5 m distance from the bottom. The acquired data are suitable for estimation of spatio-temporal parameters of water transfer in the bottom layer up and down the slope, depending on direction and intensity of alongshore current. Preliminary analysis of the first installation data confirmed the presence of bottom water transfer along the slope perpendicular to the shore. Also, in case of intense alongshore north-western current, a descent of the bottom layer water was observed. Such manner of water transfer conforms to both geostrophic adjustment and dynamics of the bottom Ekman boundary layer. However, variability of water density in the bottom layer, caused by vertical water transport, had about the same range as density fluctuations in the water column on the same depths. This fact disputes the effectiveness of Ekman transfer in the bottom layer as a water ventilation mechanism for the upper part of continental slope of the Black Sea (Zatsepin et al., 2007; Elkin, Zatsepin, 2017).","PeriodicalId":169855,"journal":{"name":"DEDICATED TO THE 90TH ANNIVERSARY OF PROF.

Information synchronously obtained, both with the help of remote sensing satellites (radar and optical sensors), infrared portable pyrometer, and onboard the RV (CTD probe as part of a shipboard flow system), was used. At the same time, seawater samples were taken from the sea surface layer, followed by laboratory analysis of their bio-optic and geochemical characteristics. Hydrophysical characteristics and submesoscale structure of the Shakhe River outflow at the test site studied both remotely and contactly, gave identical results. This makes it possible to further efficiently use these instruments on board of RVs to study the river outflows in the Black Sea. At the same time, portable infrared pyrometers make it possible to obtain significantly better spatial resolution in terms of temperature compared with satellite instruments, while satellite images can detect river outflows in the sea, their boundaries and structure.","PeriodicalId":169855,"journal":{"name":"DEDICATED TO THE 90TH ANNIVERSARY OF PROF.

The study is based on the measurements of the moored acoustic Doppler current profiler. Data analysis showed that under the action of the typhoon a field of currents with inertial oscillations (IO) of anomalous characteristics was formed in the bay. It is found that the spectral energy of the IO of currents with left and right rotation are of the same order while the major axis of the hodograph of the speed of these currents exceeds its small axis by an order of magnitude. A change of the inertial frequencies of the currents with cyclonic rotation, as well as the “red shift” of this frequency in the bottom and the “blue shift” in the surface layer of the inertial currents with anticyclonic rotation were found. Parametric IO interaction with anticyclonic rotation and the synoptic component of the currents with the same direction of rotation was detected. It has been suggested that the anomalous characteristics of inertial currents with two types of rotation are due to their interaction with the low-frequency component of the stream of Primorsky Current induced by the typhoon.","PeriodicalId":169855,"journal":{"name":"DEDICATED TO THE 90TH ANNIVERSARY OF PROF.

Such cases are observed, as a rule, at night and more often in the cold season of the year. The main pollutants in these plumes are sulfur dioxide and nitrous oxides, concentration of which in the region of Lake Baikal (70 km from the source) can reach the level from hundreds to thousands µg/m3. In the process of transfer, nitrogen oxides are partially oxidized by atmospheric ozone to nitrates (mainly to nitric acid), while ozone concentrations in the plume zone drop to zero, completely expending on oxidation.","PeriodicalId":169855,"journal":{"name":"DEDICATED TO THE 90TH ANNIVERSARY OF PROF.
