Bottom was -- if the surface of the ocean bed was lower than 45,000 meters they would have to look at other means of mapping the bottom that is a remote submersible. and we understand that equipment has been on stand by for some time and it may be flown out in the next day or so. this is one of those robotic vehicles that can go below 4500 meters. >> the new zealand searchers did spot potential debris. >> they have. we understand it has been photographed and it may have been picked up. were not ...

Down to about three miles down. i think we can show you some pictures. quite an extraordinary device. see if we have footage of that. there it is. what that will be able to do is called the blue fin 21, is go all the way down to the ocean bed, which is three miles down. it goes very slowly down there. it cant cover the area in the same way that the ocean shields pinger detected it was dragging at 4,000 feet can do. so basically it will be a slow process, heavy going, but it has a much better cha...

How much more narrow do we need it before the robots go in. >> the thousand sand fofoot lev doesnt say its not here. it does say im getting something here, lets explore it. you look at the path where the ocean shield went and if you get this other pinger, lets look up here a little bit since we know theres some kind of signal there, lets find out if its legitimate and the lower level. >> weve forgotten how many aircraft are out looking for floating debris and theyve seen nothin nothing. >> again...

370. theres a usual process we have been used to in the past of doing that. usually it involves identifying surface debris and getting down on the ocean bed. >> how confident are you that this is 370? >> i still think that we have a few facts that we need to get our heads around. but in the absence of anything else, im confident the data and what ocean shield has picked up so far is going to lead us to the location. >> thank you for that. david, authorities have analyzed the signals from saturda...

They are believed to be consistent with those of a flight data recorder. >> but officials say it is still too early to deploy the navys bluefin deep water robotic search vehicle. they want to further triangulate the black box before they do that. >> yes, it is a very slow process in the underwater vehicle. and officials say this particular area of the ocean bed is heavily covered in silt. >> mr. houston also said there is a weak front moving in. >> yes, it will be complicated. this region, we kn...

Operation. >> richard, where do you think this investigation stands? youve been covering it from right at the beginning. they heard the pinging going on for two hours from one box, they think another box another 15 minutes. in order to detect those pings youve got to be a mile or two maximum away. even if they are not hearing these pings again, theyve got to be relatively close to this area. >> thats the slight unknown. the exact distance and the exact size of the search field, if they never hea...

To pick up these pings. but a slow process. and the ships will be sailing very slowly. only about 5-kilometers an hour. in order to, you know, cover a detailed area of the ocean bed. he they are covering about 240-kilometers, a tracking area of 240-kilometers today in the hope they might pick up something. but so far, there is no news whatsoever of any kind of success in this area. >> roger, thank you. >> thank you very much. greta. >> and the black box battery can and will die at any minute now...

The emergency the pilots were placing and the inconsistent information they were getting. there was a great deal of information readily available. here we dont know whether the information was unavailable because it was disabled or turned off or due to electrical failure or some other cost. we just dont have that kind of information. >> lets talk about the apparatus or assets out there. right now there is incredible state-of-the-art technology being used searching for sonic transmissions and a g...

>> the pinger is transmitting a very high frequency signal. it does have mechanisms to translate the high frequency sounds to a noise and register it. when we heard it, it is like ping, ping, ping. you cant hear it if it is in the room. it is so high frequent sichlt it has to be done slowly and at a distance of no more than a couple of kilometers away from it. the difficulty is the depth of the water versus the topography under water, what the actual seabed or ocean bed is looking like. put all ...
