Deep-sea rescue

摘要

During recent sea trials aboard the RRS James Cook, a 300-kilogram benthic lander failed to respond to all of its acoustic release commands, leaving GB£100,000 of scientific equipment on the seabed at a depth of 2000 metres.rnOn the same trials a HyBIS (hydraulic benthic instrument and sampler), devised by Dr Bramley Murton of the National Oceanography Centre, Southampton (NOCS), UK, and designed and manufactured by Hydro-Lek, UK, was undertaking its first deepwater deployment. Its primary role is to take seabed samples at depths of up to 6000 metres.
