Titan submarine: passengers would hear acoustic signals from the search team, says oceanographer

Sounds used by sonar equipment in the search for the missing submarine in the Atlantic echo without results. The case is reminiscent of the search for MH370, the Malaysia Airlines flight that disappeared from radar in 2014, a leading oceanographer told CNN .

“When I first heard about the beats, I said, ‘Oh no, here we go again.’ In the (search for) Malaysia Airlines, we heard crashes quite often, and it always turned out to be something different,” he told CNN David Gallo, Senior Advisor for Strategic Initiatives at RMS Titanic Inc.

However, authorities “will likely start moving ships and tools in that direction, whether identified or not, because time is short,” added Gallo.

Gallo’s company has exclusive salvage rights at the Titanic wreck site. He said tapping the vessel to transmit noise is “something PH Nargeolet would certainly do”. Paul-Henri Nargeolet, a renowned explorer, is one of the passengers stranded on the submersible.

“One of the thoughts I have is: did the (researchers) make a return signal, acoustically, to signal the submarine that we heard their signal?” said Galo.

“Sound is very easily transmitted across the ocean… you would hear it on the submarine for sure.”
