This prompted UK Deputy Prime Minister (and Hull MP) John Prescott to ask the Marine Accident Investigation Branch of the Department for Transport to carry out extensive surveys of the wreck, which it did in 1998 and 2002. During the latter part of the underwater survey in 2002, samples of bones and other human remains were recovered from the wreck, DNA tests conducted by the Forensic Science Service established that the remains came from four of the Gaul's crew. This finding quelled suspicions that the crew had been taken from the vessel by the Russians during cold war hostilities.
