Cruising Coastlines: Mapping With the Autonomous Surface Vehicle

The Autonomous Surface Vehicle (ASV) is a custom prototype that was built for the to create high resolution sonar maps of the seafloor in shallow water. The ASV assisted E/V Nautilus in identifying target ROV dive sites for the expedition to locate and identify submerged ancient shorelines in July 2017. This diesel-powered vehicle can go for 14-16 hours maximum at a speed of up to 5 knots. Designed for mapping from the draft to 150-200 m, radio frequency communication sends data back to scientists from up to 8 km away. Click through the album to learn more about the capabilities of this unique mapping instrument that is still in development!
