CTD data over a repeated section in the Vema Channel

Abstract

We present a CTD dataset of 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 is a narrow conduit for Antarctic Bottom Water across the Rio Grande Rise. The measurements at CTD stations (Conductivity-Temperature-Depth) across the Vema Channel were started by German scientists in 1991. In 2002, Russian scientists took part in this work and have been establishing stations across this standard section until recently. The data were collected using the Sea-Bird Electronics SBE-19 profiler. The data are presented in tabular format. The data are available at http://dx.doi.org/10.17632/hh4hhn6ny8.1.
