A team from Cardiff University are working on a new way to "locate objects impacting on the sea surface" and this could hold the key to finding the airplane that disappeared in March 2014 whilst flying from Malaysia's capital of Kuala Lumpur to Beijing, China. MH370 has never been found but it is thought to have crashed into the Indian Ocean.
Dr Usama Kadri from Cardiff University's School of Mathematics and lead author of the study said: "By using existing detectors dotted all around our oceans and listening out for signatures from these deep ocean sound waves, we've uncovered a completely novel way of locating objects impacting on the sea surface. Tracking these acoustic gravity waves opens up a huge range of possibilities, from locating falling meteorites to detecting landslides, snowslides, storm surges, tsunamis and rogue waves."
The team have also detected two "remarkably weak signals", and whilst they can't be sure it comes from the missing plane, they hope this new way of detecting information will help authorities search for the plane.
Dr Davide Crivelli from Cardiff University's School of Engineering, and co-author of the study, added: "Our study was initially motivated by a desire to gain more knowledge about the incident involving flight MH370, using data analysis techniques that can pick up and locate much weaker signals.
"Though we've located two points around the time of MH370's disappearance from an unknown source, we cannot say with any real certainty that these have any association with the aircraft. What we do know is that the hydrophones picked up remarkably weak signals at these locations and that the signals, according to our calculations, accounted for some sort of impact in the Indian Ocean.
"All of this information has been passed onto the Australian Transport Safety Bureau and we anticipate that both now, and in the future, this new source of information could be used in conjunction with a whole of host of other data that is at the disposal of the authorities."
