Abstract

The Dead Sea is the world’s lowest water body and among the saltiest (330ppt). To enable multi-beam coverage of this historical lake, ELAC Nautik took up the challenge of modifying their SeaBeam 1050 multi-beam to deal with extreme sound speeds by introducing a firmware ‘tweak’ changing the beamforming direction to account for a higher sound speed which was at that time not exactly known. While data acquisition was possible, initial results showed severe refraction issues that required a complicated procedure of ‘de-tweaking’ and re-computing.
