Researchers from University of Delaware are in the midst of a multiyear study with Delaware State University researchers to better understand the behavior and migration patterns of sand tiger sharks. In the latest phase of the study, an underwater robot is being unleashed to hunt down and follow these seemingly placid predators.
The Oceanographic Telemetry Identification Sensor (OTIS) is a remote-controlled underwater device that looks very much like a yellow torpedo. Normally used for testing water conditions, the researchers have outfitted OTIS with acoustic receivers that can recognize signals given off by transmitters. OTIS will track sharks that have been previously tagged with these transmitters as they travel through their coastal habitat.
