The ice had barely retreated from the coast of northern Lake Huron this spring when a group of farflung researchers converged in Rogers City, Michigan. They were there to map unexplored areas of Thunder Bay National Marine Sanctuary. If all went well, they would discover new shipwrecks and natural features such as sinkholes, fish habitats, and interesting geological formations.During the two-week expedition, researchers mapped areas within the sanctuary with a multibeam sonar system aboard autonomous surface vehicle ASV BEN (Bathymetric Explorer and Navigator) from University of New Hampshire’s

GeoSwath 4R system is pre-calibrated so that the survey operation can commence immediately on arrival, and no time is wasted running additional survey lines.    Its shallow draft, high top speed and maneuverability combined with the stability of a catamaran hull make it ideal for use in both marine surveys and on canals, river and lakes. The ability to steer tight survey grids makes it a fast and accurate addition to the surveyor’s portfolio.   The new GeoSwath 4R system offers unsurpassed productivity in shallow waters with at least 12x water depth coverage right up to the waterline
