Abstract

Several features probably formed by contour bottom currents were recognized on the Rio Grande Rise by high-resolution seismic survey in the transatlantic profiles of the #32 and #52 cruises of R/V Akademik Ioffe carried out by the Shirshov Institute of Oceanology, Russian Academy of Sciences. The deposits of mixed turbidite–contourite sedimentary systems near the base of its southern and northern slopes seem to be formed as a result of the interaction of downslope gravity flows and the along-slope deep-water Lower Circumpolar Water + Weddell Sea Deep Water current. Sediment waves and disputable small plaster contourite drifts are probably formed by circulation of the Antarctic Intermediate Water in the Cruzeiro-do-Sultrough at the top of the rise.
