DICT participates in recent Bathymetric survey aroundthe Dyer Island system and inshore Reefs.

The Dyer Island Conservation Trust has recently collaborated with Underwater Surveys (PTY) Ltd, a private marine services company based in Cape Town. Mark Prowse and Hydrographic Surveyor Andrew Matthew towed the company survey boat from Cape Town and spent two full days at sea in the Gansbaai area. The 6.7m custom-finished vessel Blue Dolphin is a computer lab on water and is fully kitted out with a high-resolution multibeam echosounder which is pole-mounted underwater over the stern and complemented by high-accuracy Real-time Kinematic (RTK) GPS positioning and vessel attitude sensing equipment. Huge amounts of data are collected and logged onto a high-powered PC running some really advanced survey software which displays bathymetric data in real-time for the operators. The aim of this visit was to conduct a detailed bathymetric survey and produce high resolution three dimensional charts of some interesting areas around the Dyer Island system and the inshore regions seafloor and topography.
