REMUS SharkCam is a specially outfitted REMUS-100 autonomous underwater vehicle (AUV) equipped with video cameras and navigational and scientific instrumentation that enable it to locate, track, and film up close a tagged marine animal, such as a North Atlantic white shark (great white). The vehicle is pre-programmed to home in on a signal from a transponder beacon attached to the animal at depths up to 100 meters (330 feet) and in a variety of patterns and configurations.
REMUS SharkCam uses an omni-directional ultra-short baseline (USBL) navigation system to determine the range, bearing, and depth of a tagged animal. It then closes on the animal to a pre-determined stand-off distance and position (left, right, above, or below) and to film it swimming and interacting with its environment with minimal interference with the animal's behavior. Another system on the vehicle permits it to communicate with scientists on the surface every 10 to 20 seconds and to receive commands from the surface to change speed, depth, or other mission parameters as necessary.
REMUS SharkCam has been tested on white sharks and basking sharks near Cape Cod and on white sharks near Guadalupe Island on the West Coast of Mexico. Plans are currently underway to use the system to follow other large marine animals such as sea turtles. Visual and numerical data from the vehicle promise to open up new ways of studying the behavior of marine animals in the wild interacting with their natural habitat.
