Autonomous Underwater Vehicles (AUVs) are unmanned, untethered vehicles used to conduct underwater research. AUVs operate independly of humans and, in fact, have no physical connection to the operator. Rather, AUVs are programmed or controlled by operators who may be on a vessel or even on shore, who tell an AUV where, when, and what should be sampled. AUVs carry a variety of equipment for sampling and surveying such as cameras, sonar, and depth sensors. Unlike ROVs, which are tethered to the ship, AUV data is not transmitted live during the dive. Instead the AUV stores all of the data, including images, video, and other sensor data on onboard computers until it can be retrieved after the AUV is recovered at the end of a dive.
