SOUTHERN OCEAN, SURFACE WATER MASSES, HYDROLOGICAL FRONTS, WEDDELL'S SEA
Object of research - hydrological structures Antarctic frontal zones of the Atlantic sector of the Southern Ocean and areas CCAMLR 48.1, 48.2.
The purpose of the GDR - to identify the hydrological structure of the marine environment in the South Atlantic and the Atlantic sector of the Southern Ocean according to observations in the summer of 2019 - 2020, made aboard the Ukrainian fish-krill trawler - super "Commonwealth Sea"
Methods and materials: the primary data of measurements of characteristics of a condition of waters received by means of the modern measuring software and hardware complex "Ferry Box" are used. Traditional methods of graphical, statistical, cluster and T, S-analysis were used to process the obtained data. For a comprehensive analysis of the obtained materials, satellite data were used: from drifting buoys of the ARGO program (ARGO), COPERNICUS Marine Monitoring Service, visual data of the AERONET system.
As a result, such oceanic structures as the Bengal Current, the Southern Subtropical Front, the Subantarctic Front, as well as the Southern Polar Front and the Second Frontal Zone have been identified. Mordvinov Island and the transitions between them. A comparison of the results of measurements of the parameters of the upper water layer in the transatlantic section of 2018 and 2019-2020. In order to determine the causes of krill concentration, a comparison of the characteristics of the surface water layer in areas of industrial vessels and beyond. It is shown that in the zone of intensive fishing the concentration of dissolved oxygen is higher, and the value of carbon dioxide as an indicator of phytoplankton biomass is lower than in the zones of single trawling.
The results of this work will expand knowledge about the Southern Ocean ...
