The primary goal of the cruise was to search for cold-water coral mounds in the West Indian Ocean. Data were recorded in the EEZs of Mayotte, Tanzania, Mozambique, and South Africa. These studies were endorsed as an UN Ocean Decade 2021-2030 of Ocean Science for Sustainable Development activity. This dataset includes 5 bathymetric grids produced based on the MBES data collected in the EEZ of Mozambique between 2024-08-27 and 2024-09-03. The grids represent 5 surveyed areas: 1) transit_1 to the working area; 2) working area off Zambezi Delta; 3) transit_2 to the next working area; 4) working area off Limpopo River; 5) transit_3 to South Africa. Postprocessing of raw .all files was performed onboard by Evgenia Bazhenova and Alissa Bach using the QPS Qimera software. Data quality control included 1) verification that the SVP data were applied correctly based on the time and location; 2) blocking outer beams and in-turn data to ensure the best possible quality of the overlapping swaths, 3) manual point cloud cleaning if required. Additional postprocessing of the working dataset off Zambezi Delta was carried out by Md Mumit Hassan in the frame of his work towards the master thesis at the HCU Hamburg. All the other grids were additionally cleaned by Yukari Asakura using the MB-System software. Transit data have degraded quality due to the bad weather conditions. Depths measured by the MBES are reported in respect to the water level. Only static draft was taken into account. No tidal corrections were applied during the data acquisition or data postprocessing.
