Oceanographer Dr Simon Boxall has criticised the occupants of the Titan exploration submersible, saying that there doesn't appear to be any element of research, "this is purely tourism", telling Vanessa Feltz "whether it's going into outer space or oceans, they both carry incredible risk."
He goes on to raise the question of whether people were being put at risk while undertaking the current search and rescue mission.
Experts are searching for a missing submersible in the area where noises have been heard beneath the surface, the US Coast Guard confirmed.
Captain Jamie Frederick told reporters in Boston on Wednesday the cause of the noises in the North Atlantic was still unconfirmed but insisted the efforts to find the five missing people aboard the Titan was still “a rescue mission”.
The vessel lost communication with tour operators on Sunday while about 435 miles south of St John’s, Newfoundland, during a voyage to the Titanic shipwreck off the coast of Canada.
