>> it is density, water moves because it is dense, if it is salty or cold, the water is actually water that cuts across the sea bed. >> of water that is more dense? >> yeah, it floats, it started to use the antarctic and pours into the basins, the lakings are own more amazing that you can go to the bottom of the ocean and see what looks like a lake at night. >> would it interfere with the towed pinger locators? >> potentially it could, it makes a little bit of extra noise, there are some that are in that frequency range. there is the physical movement of the propeller and pieces on it that can...

Kilohertz and repulse out every second, a short burst. so if you don't know which one is which, it would be very difficult to tell. but the interesting thing is that if you find one, it is quite likely that the other one will not be too far away depending on how the aircraft hit the water but it's quite likely that they will be within a mile of each other. >> and lastly, for david soucie, do these batteries weaken or is it what happens with my iphone, all of a sudden it's dark? >> there's two things going on. you have the repeated signal every second and then you have the frequency range as we...

Dvdr that has the pingers attached to them, which one is which in order to locate this signal? >> well, they have to know what to be listening for. it's like trying to listen for extra terrestrial life. you have to know which direction to point your antenna. which frequency range to listen on. what the duration would be. whether or not what you're receiving is noise or is, in fact, what you're looking for. and the manufacturer as well as the installation and operation can no doubt tell you exactly how each of these was programmed. >> are they all 37.5? >> i believe it's programmable. >> okay. ...

Bottom. >> do you think this is the black box or a natural phenomenon? >> i'm not a sonar expert, but i think if they are hearing something that is in that frequency range, then there's a chance this could be the black box, i think it's a long shot, but i don't know the chinese operators. if the operators had herd this signal and i worked with the operators in the past. those guys are very good. and if they are hearing these pings and they get any sort of confirmation on it, then they have a very good chance it is

I understand it, that's between 10,000 to 15,000 feet deep and 932 miles from perth, australia, which is like new york city to jacksonville, florida, talking about the scope of this area. when you're talking about depth like that, how difficult is it to actually go and get those boxes then? >> well, it can be challenging at times with currents and other factors, but we've done it before. this isn't the first time that we've had to operate at deep ocean depths in order to recover things. so salvage people are very good at what they do. once we get the location -- >> what other things can make t...
