• The US Coast Guard is continuing its search for the lost Titan sub even after its oxygen likely ran out.
• Rear Adm. John Mauger told TODAY that rescue efforts will continue.

The US Coast Guard is continuing its search for the lost Titanic sub, saying that although oxygen on the vessel has likely run out, "people's will to live" is an important factor.

On Thursday morning, Coast Guard commander Rear Adm. John Mauger told the "TODAY" show that the situation is similar to other complex rescue operations and that even if the submersible is running low on oxygen, "People's will to live really needs to be accounted for, as well."

Mauger, who is spearheading the search, added that new assets and capabilities to help find the sub are being used in the search on Thursday.

Early Thursday morning, a USCG spokesperson told Insider that search-and-rescue efforts will continue after the 96 hours of oxygen on the sub likely run out.

"We'll always continue searching until we are absolutely certain that there is going to be no chance of survival," Matthew Schanck, search-and-rescue expert and founder of MarSAR International, also told Insider.
