Acoustic Ping News Today

Most promising lead yet in the hunt for flight 370. i spoke earlier with commander williams marks, hes the public affairs officer for the u.s. seventh fleet. remember, the u.s. is the one controlling the pinger locators. we got him from yokosuko. this is the most encouraging news weve heard. tell us what we know. >> well, it is encouraging. u.s. navy counterpart did detect a ping signal, actually, over a pretty significant amount of time in the search area. at first the cpl, or code pinger locat...

Breaking overnight in the search for flight 370, the signals detected by pinger locaters are those consistent with aircraft black boxes. what do we know about the pinger locaters used by the chinese and australian ship ocean shield. jeff weiss is here. youre here to discuss all these possibilities. >> right. >> the location these signals were detected, are you as optimistic as authorities in australia are that this could be what were looking for? >> i would say guardedly optimistic remember this...

With surface debris is very small. as authorities say, miracle do happen. >> lets compare the chinese pinger locater as opposed to whats being used on board the "ocean shield." a tow locater. >> what the chinese are using is a system designed to be held by divers, so very shallow water. you sort of aim it in the direction that you think the ping might be located. its very directional. >> so in a situation like this, thats a little risky to be using that for such a gigantic area. >> right. the ma...

Mirror, gathering the sound so it can detect a much fainter signal. further down in the water. >> 20,000 feet. >> this is a lot better bet. >> moving on to what are the reasons pointing us to believe that these pings are likely the wreckage. >> first of all, the frequency does not occur in nature. this is not something that a whale can make the sound. >> water can play tricks on you. >> it is noise si under water. i would take this against the argument of the validity of the pings oovps. there a...

Shield has detected signals consistent with those of aircraft black boxes. >> the audible signal sounds to me just look an emergency locator beacon. >> reporter: the "ocean shield" picked up two distinct pinger alerts here. these signals detected 350 miles away from an area where a chinese ship picked untwo audio signals on saturday. britons "hms echo" has been moved there to investigate. they do not believe its related to the "ocean field" find. >> id say its unlikely. but in deep water, funny ...

Was from the military radar. and that theres no secondary ping. theres no ping saying yes, this is that aircraft. theres nothing that says, yeah, i am flight 370s. so looking at radar, when you do from that perspective of not knowing when youre looking at, it can vary quite a bit. theres quite awe few dots out there that have no meaning, other than a flock of birds perhaps. or other items that pop up on the radar. and on typical radar, you discard those things, you turn your intensity down and f...

Area. you can see it here on the map. this is where the australian ship was. theres also a chinese ship that had pinger locator data. theyre not as confident in that. were going to stick with what were hearing from the australians using the quilt right now. theyre bothing that area. two hours. and then had to turn around which is is a massive process. and then several minutes to try to re-establish it. if they can narrow down that search area, then they can use underwater subs to map the ocean b...
