- 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 robot was looking for signs of the missing Titan submersible.
The United States Coast Guard said on Thursday that a "debris field" has been found in the depths of the North Atlantic in the extensive search for the missing Titanic 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, Canada, the Coast Guard said.
"A debris field was discovered within the search area by an ROV near the Titanic," the Coast Guard announced in a tweet. "Experts within the unified command are evaluating the information."
Search-and-rescue crews have been looking frantically by land, air, and sea for OceanGate Expeditions' Titan sub carrying five people on board since the vessel was reported missing on Sunday.
Disaster unfolded for the 21-foot carbon-fiber and titanium sub and its passengers shortly after the vessel started a dive on 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 floor.
The Coast Guard said it will hold a press conference later Thursday to detail the findings from Canadian ship Horizon Arctic's ROV on the sea floor 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."
