to do. bring us up to speed. reporter: hi, christine. well, they re saying these findings are absolutely extraordinary. the australian vessel, the ocean shield detecting not one, but two separate acoustic events. the first event lasting 2 hours and 22 minutes, the second event lasting 13 minutes, consisting of two separate signals, signals that authorities are saying are consistent with the cockpit voice recorder and the inflight data recorder, but at the same time here in perth, they are urging caution, saying it will take some time to verify these findings. take a listen to what angus houston, the man spearheading this international search effort, had to say at a press conference earlier today. i need to be honest with you, it could take some days before the information is available to establish whether these detections can be confirmed as being from mh-370.
