The NR-1 Submarine
The JASON VII team will use NR-1, the Navy's nuclear submarine, to map ancient coral reefs. One of these reefs, the "hump," has never been explored before.
The NR-1 is a compact, nuclear-powered, electric-drive undersea research and ocean engineering submarine. Her operation depth encompasses all of the continental shelves and much of the continental slopes, while her nuclear power plant provides a far greater endurance than any other research submarine.
The NR-1 is capable of ocean search missions such as locating and
identifying objects or ships lost at sea, and in situ examination
and recording of ocean topographic and geological features.
The ship is equipped and has the capacity for work near or on
the seabed, performing sample gathering, recovery,
implantation, or repair of objects in the ocean. The installed
equipment can be supplemented by scientist-supplied sensors
to conduct experiments and obtain knowledge of the ocean's
chemical, thermal, optical, biological, and acoustical
