Image Of the Day caption:
A variety of communication and tracking devices line the top of Sentry, allowing scientists to stay in continuous touch with the nearly 10-foot-long autonomous underwater vehicle. Keeping track of the vehicle is critical; Sentry explores depths to 19,685 feet for up to 40 hours at a time. Devices shown here include (right to left) a radio direction finder beacon, a strobe light, a radio antenna for on-deck and on-surface control and communication, a transponder-release (for tracking and simple communication), a GPS irridium system (which sends email messages via satellites when Sentry surfaces), and an acoustic transducer (for sending large volumes of data when the vehicle is on the seafloor).
