OTIS is a remote-controlled device that looks like a yellow torpedo and normally darts through the ocean to sample water conditions. Oliver outfitted the apparatus with acoustic receivers that can recognize signals given off by the sharks’ transmitters as they travel through coastal waters, rapidly reporting the encounters.
The technology allows the course of OTIS to be changed to follow the sharks and test the water surrounding them. Sharks were initially found on Oct. 10, and OTIS doubled back to again locate the sharks. The approach will help scientists follow where the sharks are going more quickly than conventional tracking techniques
