Finding Shipwrecks Faster

摘要

The acoustic Remus 100 AUV scans, for example, a one-square-mile patch of seafloor with sonar, a process that requires about 4.5 hours. The sonar bounces off large objects to create highlights and shadows that reveal the rough outlines of a wreck [see above]. If the sonar images indicate a shipwreck, the video Remus goes in for a targeted scan of the area. The video Remus cannot take high-quality images, so any shipwrecks confirmed by the visual data are later photographed by a team of divers.
