Abstract


We present a comprehensive regional bathymetric data compilation for the southwest

Indian Ocean (swIOBC) covering the area from 4°S to 40°S and 20°E to 45°E 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 data-constrained 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.
