Benthic sampling was conducted during the DIVA 1-3 expeditions on board RV Meteor between 2000 and 2009: DIVA 1 (Me 48/1), 06.07.2000-02.08.2000, Walvis Bay – Walvis Bay; DIVA 2 Me 63/2, 25.02.2005 – 30.03.2005, Cape Town (South Africa) – Mindelo (Cape Verdes); DIVA 3 Me 79/1, 10.07.2009 – 23.08.2009, Montevideo (Uruguay – Ponta Delgada (Azores). Study area The study area encompasses five abyssal basins of the equatorial and South Atlantic, including the Argentine and Brazil basins located in the SW Atlantic, the Guinea basin in the equatorial Atlantic, as well as the Angola and Cape basins in the SE Atlantic. The hydrography of South Atlantic surface waters is dominated by the South Atlantic subtropical gyre, which is clockwise bounded by the Benguela current system in the East, the Antarctic circumpolar current in the South, the Brazil current in the West and the South Equatorial Current in the North (Rhein et al., 1996; Palma & Matano 2017). Deep water masses consist of North Atlantic Deep Water ...
