FOG BLOG BREAKING NEWS LOG: 'STILL SEARCH & RESCUE' FOR SUBMERSIBLE ,CANADIAN AIRCRAFT DETECTS NOISE

Titanic sub hunt still a ‘search and rescue’ after underwater noises detected The U.S. Coast Guard says the hunt for the missing Titanic submersible is still a “search and rescue” mission with searchers detecting underwater noises both Tuesday and Wednesday.

Capt. Jamie Frederick told reporters in Boston Wednesday searchers have zeroed-in on the areas in the North Atlantic where the noises were detected, but could not offer specifics on what those noises were.

However, the revelation offered a glimmer of hope for those lost aboard OceanGate Expeditions’ Titan, as estimates suggest as little as a day’s worth of oxygen could be left if the vessel is still properly functioning.

“This is a search and rescue mission, 100 per cent,” Frederick said. Search efforts have yet to yield any positive results.

“We are smack dab in the middle of search and rescue and we’ll continue to put every available asset that we have in an effort to find the Titan and the crew members.”

At 12:18 a.m. Eastern on Wednesday, the U.S. Coast Guard had initially tweeted that a “Canadian P-3 aircraft” had detected underwater noises in the search area, which is now roughly two times the size of Connecticut – 13,023 square kilometres – Frederick said. The subsurface search is up to four kilometres deep.

Canada does not fly P-3 Orions but does use CP-140 Auroras, which are based on the Orion airframe with different avionics.
