According to the US Coast Guard, a “debris field” has been detected within the search area.
A remotely operated vehicle discovered the debris near the Titanic’s ruins.
This comes after the estimated oxygen supplies would have run out.
A spokesperson for the USCG wrote: “A debris field was discovered within the search area by an ROV near the Titanic. Experts within the unified command are evaluating the information.”
The debris was found on the sea floor near the Titanic.
A conference has been arranged for 3pm EST to discuss findings.
A massive search was launched after the sub, which was going down to visit the Titanic wreck, failed to check in an hour and 45 minutes into the trip.
The Titan submersible was estimated to have about a four-day supply of breathable air when it launched Sunday morning in the North Atlantic but experts repeatedly emphasised it was an estimate.
