- Abstract
A multibeam bathymetric survey of six mature-phase and 17 youthful-phase submarine canyons, many of which were previously unknown, on the northern KwaZulu-Natal continental shelf was undertaken in order to define the physical, structural habitat of coelacanths and to guide surveys by manned submersibles within the canyons. Five survey blocks were systematically surveyed to develop a series of colour-draped bathymetric maps and three-dimensional models of the canyons. The bathymetric data and maps were developed further to provide the basal layer of a marine Geographical Information System upon which to build all georeferenced physical and biological data of the African Coelacanth Ecosystem Programme.
