Benthoscope

Unpowered spherical deep-sea observation submersible lowered on a cable

The Benthoscope was a deep sea submersible designed by Otis Barton after the Second World War. He hired the Watson-Stillman Company, who had earlier constructed his and William Beebe's bathysphere to produce the new design of deep diving vessel, which was named from the Greek benthos, meaning "bottom".
