The Autonomous Underwater Vehicle Sentry

WHOI’s free-swimming robot Sentry completed its 500th dive on October 16, 2018. The autonomous underwater vehicle has used its sonar systems to help scientists map the seafloor, track the Deepwater Horizon oil spill, locate the voyage data recorder on the sunken El Faro cargo ship, and carry out advanced research on many other missions to help us better understand our ocean and our planet.
