Harbour search & recovery "The divers dropped down the shot lines placed using Differential GPS on the coordinates from the Gavia side scan sonar images, and found themselves within a hands reach of the targets. The Gavia AUV was the most accurate and effective search tool used in this operation, which also employed divers, towed side-scan sonars, and ROVs." Mikael R Olafsson ICE-SAR search coordinator
