Purpose
Abstract The research programme of cruise M122 focussed on a detailed study of coldwater corals (CWC) along the Namibian and Angolan continental margins. During M122, the maximum swath width of the EM122 was set to 120 degrees to improve data quality, reduce the amount of noisy data at the outer beams, and increase the ping rate.
