Until and unless we find another transmission. and then, thereafter, theyll put down the blue fin. and he said, if they do that, and this is the wording he used, because its really telling, he said, it would take many, many days if they have to scan the bottom of the ocean. and when he was asked again, he said, a long, long time. so i think what we are in at the moment now, its very clear what were in, several more days of "ocean shield" trying to find, using the pinger. >> can i jump in here to...

Just because we can hear pinger and possibly might be able to locate it doesnt mean at that moment we found the box. the box could still be several hundred yards away if not more. so still yet another layer of concern. were still a long ways from finding a really meaningful data, meaningful information to. he out. >> adding yet another variable to this unprecedented search. well continue to watch it. another day to try to reconnect with that ping and search continues. thank you so much. >> thank...

The transmission level. >> meantime, they are guarding against noise interference, limiting the number of ships and aircraft near the ocean shield. 375 miles away, search crews havent given up hope on the other pinging sounds reported by the chinese. two search areas, but so far neither has reacquired the sound they need. well, australian officials say they will keep searching for that pinging sound until there is absolutely no doubt the pinger batteries have expired. that means roughly another ...

He believes it was one of thinks teams pingers on the flight. authorities allowed him to listen to the pinger sounds just detected over the weekend. you actually heard the pinger sound that the ship picked up? >> they sent us some data. >> reporter: how did it sound is now >> like one of our pings. >> reporter: what does it sound like? listen. so its stant. as soon as it hits the water it starts pinging. >> it doesnt take a lot of water to start pinging. its designed that way. >> reporter: if th...

Plane. lets look at the underwater devices used. tom, we heard from rosa. how theyre using these different pieces of technology, how will this work? >> in a simple sense, think about what rosa said there, you can get the broadest picture from the least precise equipment. the more precise you get, the slower it all gets. you think about what the chinese were using. they basically went out with a small listening device that wasnt really designed for this type of thing. they said they read somethin...

So far that weve gotten. the night before, the same thing. >> and i thought it was awesome. >> i want to get mary in. in your experience, investigating these sorts of incidents, and this one has been as unusual as it can be, have you heard of a pinger being detected at these depths and from hundreds of miles away in different spots? >> no, not from hundreds of miles away. i mean, you can -- the most ive heard is two, three miles. the hundred miles away doesnt make sense, although i heard many ex...

Wrong area? does it mean the batteries have died? could it mean both? were going to be watching that. we have an interesting guest this morning, the man who led the search for the air france flight 447. hes going it take us through, even once they reconnect with the pinger, even once they cut down the search range for where the plane could be, what is entailed from there on? there is actually a lot more that has to happen. well take you through that. were also monitoring the pistorius trial. thi...

Will have expired. so, it will be several days more. now, until we stop the pinger search, we will not deploy the submersible. is that clear? we will not deploy it unless we get another transmission, in which case well probably have a better idea of whats down there and well go down there and have a look. >> if you dont get a further transmission -- >> yeah, the issue is that if we can get more pinger -- well, more transmissions, we can get a better fix on the ocean floor, which will enable a mu...

Researchers show us the challenges search crews face as they try to hear the ping from flight 370s data recorder. >> so this is a hydrophone. >> we drop an underwater microphone, a hydrophone, off the back of the boat as it moves farther away from a pinger thats already been submerged. and even less than 100 yards away, the ping starts to fade. distance isnt the only problem out in the indian ocean. there are other noises competing with the sound of the pinger, like sea life. one dolphin species...

This is "world news now" with john muller and diana perez. >> good tuesday morning. we will get right to it. we begin with the very latest on the search for flight 37. we just learned with the search at a critical stage, the strategy is changing. >> search crews failed to locate the ping-like transmissions, they wont send an unmanned submarine into the indian ocean as previously planned. more than two dozen planes and ships will step up efforts to zero in on finding transmissions over a more con...
