The Deep Power rescue ship carried two remote-operated autos (ROVs) able to working to a depth of three,000m.

The John Cabot, which has “side-scanning sonar capabilities”, the Skandi Vinland and the Atlantic Merlin additionally joined the search on Wednesday, the US Coast Guard said on Twitter.

Regardless of the multi-agency mission, David Concannon, an lawyer and explorer who pulled out of the Titanic expedition on the final minute, claimed that the rescue efforts have been hampered by purple tape, paperwork and an absence of urgency by the US authorities.
