An underwater ROV found a 'debris field' in the search area for the missing Titanic sub, Coast Guard says

• The Coast Guard said an underwater robot found a "debris field" near the wreck site of the Titanic.
• "Experts within the unified command are evaluating the information," the agency said.

The US Coast Guard said Thursday that a "debris field" had been found in the depths of the North Atlantic in the extensive search for the missing Titan tourist submersible.

An underwater robot discovered the debris field near the wreck site of the RMS Titanic, which lies 12,500 feet below the ocean's surface off the coast of Newfoundland, the Coast Guard said.

"A debris field was discovered within the search area by an ROV near the Titanic," the Coast Guard tweeted. "Experts within the unified command are evaluating the information."

Since the vessel was reported missing on Sunday, search-and-rescue crews have been looking frantically by land, air, and sea for OceanGate Expeditions' Titan sub, which set out with five people on board.

Disaster unfolded for the 21-foot carbon-fiber and titanium sub and its passengers shortly after the vessel started a dive Sunday to the wreck site of the Titanic.

The sub lost communication with its mothership less than two hours into its journey to the bottom of the ocean.

The Coast Guard said it would hold a press conference later Thursday to detail the findings from the Canadian ship Horizon Arctic's remotely operated vehicle on the seafloor near the sunken passenger liner.

Early Thursday, the Coast Guard announced in a tweet that the Canadian vessel deployed a deep-sea ROV that "reached the sea floor and began its search for the missing sub."
