The Navy and others monitor sound offshore to assist with endangered species research. It's likely that other monitoring equipment also may have picked up the sound, said Eric Fusil, a submarine expert and associate professor in the University of Adelaide’s School of Electrical and Mechanical Engineering. The Navy's analysis of acoustic data collected in the vicinity on Sunday morning found an 'anomaly' that could have been an explosion or an implosion around the time the sub lost contact. Yes, though not definitively, the Coast Guard said. Did the Navy detect the sound of the implosion? When asked before the debris were located, Jim Bellingham, a Johns Hopkins University expert on deep-sea operations said, the submersible could be floating on the ocean's surface, drifting anywhere between the surface and the bottom or stuck on the sea floor. With that kind of force, he said any defect in the Titan's hull could have triggered an implosion. At 12,500 feet, the pressure is more than 4,400 pounds per square inch. 'People always underestimate that impact,” Wille said. The deeper you go, the higher the pressure climbs. It’s a familiar concept to divers, who feel the pressure when they descend, breathing air regulated to match the pressure around them. On the ocean floor at the depth where the Titanic rests – 12,500 feet – the pressure is nearly 380 times greater than at the surface, said Luc Wille, professor and chairman of physics at Florida Atlantic University. “Pressure is enormous down there,” said Nikolas Xiros, professor of naval architecture and marine engineering at the University of New Orleans. Here’s a look at the difficult task the team faced, the technology used and conditions that may have led to 'a catastrophic implosion.' What happened to the Titan submersible?Īnyone who’s traveled in the mountains or by airplane understands how air pressure changes, but it’s difficult to comprehend the forces straining at every inch of the submersible as it descended the nearly 2.5 miles toward the ocean floor on Sunday. The world watched as a growing team of search and rescue experts tackled their complex and dangerous mission at extreme depths in a remote location 400 miles east of Nantucket. At least four other large pieces were found nearby, including the front and rear sections of the sub's pressurized chamber, said Paul Hankins, a director of salvage operations and ocean engineering with the Navy. An international search for a missing submersible took a tragic turn Thursday when the vessel was found scattered in pieces in icy darkness on the ocean floor.Ī remotely operated vehicle discovered the nose cone of the Titan submersible about 1,600 feet from the bow of the Titanic, authorities said.
