National Transportation Safety Board says its confirmed a vessel found at the bottom of the Atlantic Ocean is the cargo ship El Faro.

The NTSB sent out this tweet Monday:

No other information has been released.

On Saturday, the NTSB said sonar on the USNS Apache located El Faro about 15,000 feet below the surface.

Specialists on the Apache spent Sunday using a remotely-operated vehicle to survey and confirm El Faro's identity.

The next step will be to locate and recover the voyage data recorder.

El Faro went missing on Oct. 1 during Hurricane Joaquin. The storm was a Category 4 hurricane when El Faro got caught. The ship had 391 shipping containers on board, which would make it top-heavy amid Joaquin's 50-foot waves.

El Faro had 28 crew members from the United States and five from Poland. The ship was heading to Puerto Rico on Sept. 29 from Jacksonville on a regular cargo supply run.

The families of five crew members from the ship have filed a counterclaim against the owner of El Faro.

TOTE Maritime had filed a complaint, saying it shouldn't be held liable for El Faro's demise.

Attorneys representing the families of five Polish crew members say the owner's efforts to avoid liability are unjustified.

"This is remarkably insensitive to the family of lost crew members," said attorney Michael Winkleman.

Families of four American crew members had already filed lawsuits against TOTE Maritime, claiming El Faro shouldn't have gone out to sea. In a statement, the company says it remains focused on supporting the crew members' families.
