| Abstract | Cruise M132 aimed at collecting high resolution observations at the upwelling front off Namibia. The goal was to obtain a detailed understanding of the interaction between meso- and submesoscale processes occurring at the front. The major goals of the cruise were: (1) observing mixed layer eddies and instabilities at the upwelling front and assessing their horizontal and vertical structure; (2) evaluating the generation, lifetime and dissipation of submesoscale features found in the working region; (3) quantifying the lateral exchange or tracers and properties across the front. Though multibeam has been recorded during the cruise, it was not a major focus and the responsible party provided no acquisition information. |
