We put the deep ocean within reach.

 Our Vehicles. Your Tools.

NDSF operates a fleet of underwater vehicles that enables the oceanographic community to explore, sample, and map the deep ocean and to meet the needs of a changing research landscape.

HOV ALVIN

A 3-person research submersible capable of reaching 4500 meters depth and of supporting custom sensors and samplers. The Alvin Team delivers reliability built from nearly 5,000 successful dives.

ROV JASON

A time-tested remotely operated vehicle system capable of multi-day missions to 6500 meters. Observers get real-time, HD video and data, as well as physical samples from the seafloor.

AUV SENTRY

A flexible, fully autonomous vehicle rated to 6000 meters that carries a wide and growing array of instruments. The Sentry Team is also skilled at carrying out multi-vehicle missions.
