Sound from CTBTO Hydrophone of Interest to Search for Missing Flight MH 370

773 views 1 month ago
This spectrogram represents the signal that was recorded by the CTBTO's hydrophones at the Cape Leeuwin station in Western Australia at 1:34:48 UTC on 8 March 2014. Researchers are examining the sound in connection to the missing Malaysian Airlines flight MH370. The spectrogram shows the signal broken up into time and frequency. The white line is a filtered version of the sound showing an unusual signal in the middle (heard at seven seconds into the recording). The recording is speeded up by a factor of 16 to make it audible to the human ear.

"Every day we detect dozens of signals at Cape Leeuwin and most of them are from earthquakes around the Indian Ocean and ice-breaking events in Antarctica. The signal of interest came from a direction that we don't normally see so it's certainly not an everyday occurrence. Relating it to the airliner is difficult, however, especially given the large uncertainty in where and when any impact may have happened." CTBTO hydroacoustic expert, Dr Mark Prior said. Show less
