| Abstract | A physical - biogeochemical survey was carried out during M130 in the north eastern tropical Atlantic and in the western tropical South Atlantic. The main objective for the works in the oxygen minimum zone (OMZ) of the eastern tropical North Atlantic (ETNA) is to improve oxygen budget estimates. Other objectives were investigating the role of zooplankton and its vertical migration for fluxes of particulate and dissolved matter to the OMZ and advancing quantitative understanding of nitrogen fixation in the tropical Atlantic. Though multibeam has been recorded during the cruise, it was not a major focus and the responsible party provided no acquisition information. |
