Ocean (swIOBC) covering the area from 48S to 408S and 208E to 458E with a spatial resolution of 250 m. For
this, we used multibeam and singlebeam data as well as data from global bathymetric data compilations.
We generated the swIOBC using an iterative approach of manual data cleaning and gridding, accounting for different data qualities and seamless integration of all different kinds of data. In comparison to existing
bathymetric charts of this region, the new swIOBC benefits from nearly four times as many dataconstrained grid cells and a higher resolution, and thus reveals formerly unseen seabed features. In the central Mozambique Basin a surprising variety of landscapes were discovered. They document a deep
reaching influence of the Mozambique Current eddies. Details of the N-S trending Zambezi Channel could be imaged in the central Mozambique Basin.
