They found the vessel after detonating grenades in the ocean to emulate an explosion on the submarine, then cross-referenced the signals from those with sounds picked up by hydrophones when it imploded.
As a result, they found the wreck at a depth of nearly 3,000ft 290 miles off the coast of Argentina.
“A similar exercise, using either explosions or airguns of energy levels equivalent to those believed to be associated with MH370, could be conducted along the seventh arc,” said Dr Kadri.
“If the signals from such explosions showed pressure amplitudes similar to the signal of interest, it would support focusing future searches on that signal.
“If the signals detected at both Cape Leeuwin and Diego Garcia are much stronger than the signal in question, it would require further analysis of the signals from both stations.
“If found to be related, this would significantly narrow down, almost pinpoint, the aircraft’s location.
“On the other hand, if the signals are found to be unrelated, it would indicate a need for authorities to reassess the time frame or location established by their official search efforts to date.”
