Bathymetric AUV shows promise for NOAA surveying

In a step towards greater efficiency in NOAA’s hydrographic surveying, experts onboard the NOAA Ship Ferdinand R. Hassler just wrapped up the first extended testing of Coast Survey’s new bathymetric mapping autonomous underwater vehicle (AUV). From Sept 3 to 13, the vehicle completed ten missions lasting up to 16 hours during day and night, while the ship continued with its assigned hydrographic surveys in the approaches to Portsmouth, New Hampshire.
This AUV is equipped with high resolution seabed mapping equipment similar to the ship’s, including a high accuracy positioning system and multibeam echosounder capable of producing seamless maps of the seafloor.
