Commander Rear Adm. John Mauger of the U.S. Coast Guard First District shared on Wednesday morning that search efforts are being expanded after banging noises were detected by sonobuoys in the ocean.

“We don’t know the source of that noise, but we’ve shared that information with Navy experts to classify it,” Mauger said, speaking with “CBS This Morning.”

The noise that Mauger was referring to was a reported banging sound being detected by sonar technology. The banging was rhythmic, occurring in 30-minute intervals, according to an internal government memo, CNN reported.

The sounds were detected near the wreckage of the Titanic, and for four hours after additional sonar devices were deployed the sound was still being detected.

However, it still isn’t clear what the banging was, when it was heard, or for how long.

Mauger shared that the area is an “incredibly complex site” when asked how common it was to pick up noises.

“There is a lot of metal and different objects in the water around this site,” he said, discussing the Titanic’s resting place. “That’s why it’s so important that we’ve engaged experts from the Navy that understand the science behind noise and can classify or give us better information about what the source of that noise may be.”

The search for the submarine continues, and the international unified command involved in the search efforts has “reprioritized the two remote operated vehicles that we have searching in the water and the one surface vessel that has sonar capability on the surface of the water in the area of those noises to see if we can locate the source of those noises and locate the people on the submersible,” Mauger said.

Even with time running out, Mauger isn’t giving up hope of finding the submarine.

“As long as there’s an opportunity for survival, we will continue to work with this broad unified command to bring every resource to bear on the search,” he said.
