| Abstract | R/V METEOR cruise M119 was a joint effort of the Kiel Collaborative Research Centre SFB 754 ("Climate - Biogeochemistry Interactions in the Tropical Ocean") involving the BMBF joint project RACE and the German-French-African Cooperative Project AWA. The main goal was the quantification of ventilation processes including lateral and vertical mixing and oxygen advection (SFB SP A3 and A4). . The 12-kHz multibeam echosounder EM122 was used to continuously record bathymetry and water column backscatter during the cruise. The system pinged at 10-second intervals with a bin size of 8m. The data were mainly taken to study the bathymetry of the seamount ridge north of the equator along 23°W. Bathymetry was not the primary focus of the cruise. |
