The complex consists of two towed uninhabited underwater vehicles “Sound-Complex” and “SoundMAFT”. A special hydrographic vessel with a displacement of 2600 tons was converted for deep-sea towing and storage of these devices. Computer CM1420 was used for the ship’s automated system for collecting and processing information coming from an underwater hydro acoustic navigation system, a proton magnetometer, a TV system, and side and frontal sonars. The complex was operated until 1992 in the Atlantic Ocean, the Black, Mediterranean and Baltic Seas, and was decommissioned in the early 1990s. Modern issues of the operation of industrial pipelines require understanding of experience and the creation of towed uninhabited underwater vehicles at a new technological level.","PeriodicalId":122322,"journal":{"name":"Journal of Oceanological Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131144339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An autonomous robotic system allows for such continuous monitoring to observe the basic trophic levels of ecosystems, the effects of changes in sea ice conditions, and other Antarctic environmental factors affecting the marine ecosystem. The application of the proposed method allows simultaneous measurements of environmental parameters in order to assess the relationship between the physical parameters of sea currents and biological processes. By integrating the system data with ship and satellite data in postprocessing, the response of Antarctic krill populations to multifactorial stresses can be assessed.

The most commonly used k-means clustering method was applied for calculations. Two cases were considered: division into two and three clusters. The identified clusters which united points on the θ, S-diagrams (θ, S are potential temperature and salinity, respectively) satisfactorily corresponded to the θ, S-values of the Fram and Barents branches of the Atlantic water. For each cluster the thermohaline characteristics of centroids (cluster centers) were calculated, that is, the average values at the same time of temperature, salinity and potential density of each water mass. The thermohaline characteristics of centroids, estimated from the available data obtained in different years of observation, were presented in θ, S-coordinates and θ, σ-coordinates (σ is potential density). Additionally, dependences of temperature, salinity, and potential density of centroids on the year of observation were analyzed. The final results made it possible to obtain estimates of the average thermohaline characteristics of Atlantic water in different years of observation and the variability of these estimates from year to year. In particular, it was found that the values of the average thermohaline characteristics of the AW indicated a strong warming and salinization of the AW in 2006–2009 (sections along 126° E), and the response to warming was observed in all AW clusters. An interpretation of the obtained results was given. Approaches to the choice of the most optimal method of cluster analysis were considered. The results of estimating the influence of temperature and salinity variability ranges in the analyzed CTD data on the accuracy of centroids evaluations were presented.","PeriodicalId":122322,"journal":{"name":"Journal of Oceanological Research","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128378352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this area, it manifests to a lesser extent than in the northern part of the Tatar Strait (Shevchenko et al., 2011) due to the features of the bottom topography (short deep shelf) and the large thickness of the upper heated layer, but quite clearly. At the same time, deep water rises, rich in biogenic elements and mineral phosphorus, which is important for the development of young growth of kelp. In the warm period of the year, under the conditions of the prevailing southerly wind, upwelling is observed in this area sporadically (4 ̶ 5 times per season) in the form of sharp, up to 12 ̶ 15 °C, water temperature drops in the coastal area lasting from 3 to 12 days.

The highest abundance of phytoplankton (in terms of chlorophyll “a”) is typical for the coastal region, where it reaches the eutrophic state, and decreases in the seaward zone to the mesotrophic state. Brackish water conditions determined a rather small number of species of zooplankton (36 taxa) and zoobenthos (40 taxa), including invading species (4 in zooplankton and 6 in benthos). Copepoda dominated in zooplankton in the deep-water zone, while the proportion of Cladocera and Rotifera increased in the coastal zone. The abundance and biomass of zooplankton corresponded to the maximum level observed in recent years in the SouthEastern Baltic. Zooplankton was more abundant from the coast to depths of 40 m, as a result, the best feeding conditions for planktophagous fish extended at this area. In benthos, Polychaeta and Bivalvia dominated in abundance, and Bivalvia dominated in biomass. The hydrological conditions in the Russian zone determine the development of zoobenthos in two regions separated by the Gdansk depression, which is characterized by benthic “desert” conditions. The largest region extends from the coast to depths of 70–80 m, and the second – in the deep northwestern part and is confined to the Gdansk-Gotland Sill. High abundance and biomass of zoobenthos are characteristic of the Gdansk basin down to depths of 60 m, where favorable conditions are formed for benthophage fish. The species composition and abundance of zoobenthos on the Gdansk-Gotland Sill much lower and is determined by the presence of North Sea waters inflows, in particular, in 2019 there was an increase in the abundance and distribution of benthos as a result of the inflow of North Sea waters.","PeriodicalId":122322,"journal":{"name":"Journal of Oceanological Research","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131130053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The water body is exposed to intense anthropogenic impact from the Kaliningrad agglomeration, the nature of which has undergone qualitative changes in recent years, therefore, a comparative analysis was carried out with the period 2007–2016, which preceded the launch of modern treatment facilities in Kaliningrad. The Vistula Lagoon is characterized by spatial variability of hydrological and hydrochemical conditions, which was considered for 4 different types of regions (eastern, near-Baltic, central and Primorskaya Bay). The impact of anthropogenic factors on the dynamics of hydrochemical conditions had the greatest impact on the eastern region and Primorskaya Bay. The eastern region of the lagoon accounts for the main inflow of nutrients from the catchment area (from the Pregola River), and since 2016 the wastewater outlet from Kaliningrad is located here. Compared to the period before 2016, in the eastern area a significant increase of BOD5, a decrease of dissolved oxygen concentrations, a multiple excess of nitrite and nitrate nitrogen in comparison with the all of the water area lagoon were recorded. In the Primorskaya Bay, where until 2016 low-purity wastewater was supplied from the city of Kaliningrad, in 2020–2022 pollution for most of the studied indicators (BOD5, phosphate phosphorus, ammonium nitrogen) decreased and corresponded to the average values for the water area. The near-Baltic and central regions are strongly affected by natural conditions (sea water inflows), where in 2020–2022, as in the previous period, lower concentrations of nutrients were observed due to the remoteness from the main sources of pollution. Despite the decrease in the intensity of local pollution in the Primorskaya Bay in 2020–2022, the concentrations of mineral forms of nutrients remained at high levels, providing intensive development of algae (including the growth of BOD5) and eutrophication of the Vistula Lagoon.","PeriodicalId":122322,"journal":{"name":"Journal of Oceanological Research","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121879431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment was provided in a two-layer salinity-stratified aquatic environment in a cylindrical tank located on a rotating platform. Using the original application of the “cylinder method”, single axisymmetric cyclonic and anticyclonic eddies were produced in the upper layer, and their evolution was traced over 100 or more platform rotation periods (laboratory days). It has been established that the vortices lose their stability if the value of the defining parameter representing the ratio of the Burger and Froude numbers is less than the critical one. In this case, eddies either fall apart into two or more secondary vortices (strong instability) or acquire an elongated shape (weak instability). The slope of the bottom and its roughness increase the stability of eddies. For values of the determining parameter greater than the critical one, the vortices are stable and gradually degenerate due to viscous friction. In the case of a large difference in salinity (density) between the layers, the bottom roughness does not have a significant effect on the rate of upper layer eddy damping, which, apparently, is determined by the friction in this layer. A parametrization is proposed that describes the exponential law of eddy decay, which is tested on the example of the Black Sea mesoscale eddy.","PeriodicalId":122322,"journal":{"name":"Journal of Oceanological Research","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123429564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
