Officials with the National Transportation Safety Board announced Tuesday that the "black box," or data recorder of El Faro has been recovered.
The cargo ship, El Faro, and all 33 of its crew members sunk while sailing from Florida to Puerto Rico in October 2015.
According to the BBC, the wreckage was discovered a month later, but search crews weren't able to retrieve the box until now.
Investigators said in a press release that they hope the recorder will reveal information about the final hours of El Faro's voyage and the circumstances that led up to it sinking.
"The recovery of the recorder has the potential to give our investigators greater insight into the incredible challenges that the El Faro crew faced," said NTSB Chairman Christopher A. Hart, "but it's just one component of a very complex investigation."
The NTSB attempted to recover the data recorder earlier this year, but the mission was unsuccessful.
The U.S. Coast Guard Marine Board of Investigation is still trying to determine whether negligence, commercial pressure or poor safety guidelines had anything to do with the ship sinking, according to CNN.
