Seawater properties in two intense rings the South Atlantic are considered. One ring separated from Brazil Current and other Malvinas Current. The analysis is based on CTD casts SADCP measurements onboard velocity profiler. optical properties, chemical parameters, methane concentration, biological such as primary production, plankton, fish were also analyzed. Analysis of strong differences between eddies supplemented by observations whales birds region.
Purpose.The paper is aimed to analyze (i) peculiarities of the oxygen content and distribution in Black Sea waters (ii) ratio observed changes distribution, total primary production level cold intermediate layer ventilation.Methods Results.The expedition data (2015)(2016)(2017)(2018)(2019) as well array from Oceanographic Data Bank Marine Hydrophysical Institute, RAS, were used content.The for deep part (exceeding 200 m depth) selected.To values, shipboard fluorometric measurements...
