Description

This dataset contains CTD casts at repeated sections across the Vema Channel in the South Atlantic approximately along 31°12' S between longitudes 39°18.0' W and 39°30.0' W. The Vema Channel connects the deep-water parts of the Argentine and Brazil basins. The densest and coldest Antarctic Bottom Water spreads through this channel. The depths of the Vema Channel exceed 4600 m. Its width at its narrowest part is approximately 15 km. The channel was discovered in the 1950s and hydrological measurements began in 1972. The CTD-casts in the region of the standard section across the Vema Channel at latitude 31°12' S have been made 25 times from 1991 to 2020. In some years, a section of 3–6 stations was carried out, sometimes only one station at 31°12' S, 39°18' W was occupied. In this dataset, we present only the data of ten Russian sections.
