US Coast Guard Investigates Mysterious Noises in Titanic Search Area

The US Coast Guard has deployed more ships and vessels to search for a submersible that disappeared on its way to the Titanic wreckage site. The search area is twice the size of Connecticut in waters 2 1/2 miles deep. The submersible had a four-day oxygen supply when it put to sea around 6 a.m. Sunday. The lost submersible could be as deep as about 12,500 feet (3,800 meters) below the surface near the watery tomb of the Titanic. The US Navy is sending a specialized salvage system that’s capable of hoisting “large, bulky and heavy undersea objects such as aircraft or small vessels."
