| Abstract | Cruise M116/1 is a contribution to the DFG Collaborative Research Project (SFB) 754: “Climate-Biogeochemistry Interactions in the Tropical Ocean” with the main goal to better understand the supply of oxygen to the oxygen minimum zone (OMZ) of the Tropical Atlantic with a particular focus on the role of regional advection, mesoscale and sub-mesoscale processes for lateral and vertical oxygen fluxes. The 12 kHz echosounder EM122 was in use during the whole cruise and delivered high quality bathymetry data without noticeable interference. Logging for the EM122 data started on 4th of May 2015. One strong source of noise, which affected or even destroyed especial the OS75 data, due to the position in the ship hull, was the bow thruster during stations. Bathymetry was not the primary focus of the cruise. |
