Peculiarities of Water Circulation in the Central Part of the Bransfield Strait in January 2020

The results of measurement of the thermohaline parameters of water and currents in the Bransfield Strait in Antarctica during the expedition of the Shirshov Institute of Oceanology, Russian Academy of Sciences, in 2020 are presented. A section of nine stations across the strait located in its central part and vertical distributions of temperature and salinity are analyzed. Intrusion of deep water from the southern branch of the Antarctic Circumpolar Current was found. Estimates of the current velocity and water transport are given. The total transport to the northeast was 5.03 Sv (1 Sv = 10(6) m(3)/s).
