Akademik Ioffe

Akademik Ioffe is a research vessel, named after the Soviet physicist Abram Fedorovich Ioffe.

Built in 1988, the vessel has a displacement of 6,600 tons, and a length of 364 ft. Akademik Ioffe  and Akademik Sergey Vavilov were built as a joint project. Both ships feature a vertical shaft about two meters in diameter, which opens from the main deck into a special room, from which an acoustic receiver or a transmitter can be lowered to below the waterline by means of a winch. The vessels were used for experiments on the long-range propagation of sound in the ocean.

The vessel belongs to the Institute of Oceanology. P. P. Shirshov, of the Russian Academy of Sciences.

She was chartered by One Ocean Expeditions until 2019.

The vessel ran aground west of the Astronomical Society Islands in the Gulf of Boothia, Nunavut, Canada in August 2018. There were 126 people on board; none were lost.
