“AUV” stands for autonomous underwater vehicle. AUVs are unmanned underwater robots, and as their name suggests, they operate independently of humans. Unlike remotely operated vehicles (ROVs), which are tethered to a service vessel, AUVs have no physical connection to their 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 transmit video via their tethers almost instantaneously to a control room on a ship, an AUV stores all data, including images and other sensor data, on onboard computers until it can be retrieved after the AUV is recovered at the end of a dive.
