Understanding is because of the way sound can refract under water, that is why you're getting these locations. >> when you look at the graphic, i think you can see where the ship was or the pinker was -- pinger was, it doesn't mean that is where the plane was -- >> why is it spread out? because sound bounces around on the water? >> exactly, sound bounces around, and depending on where the tpl is, the sound, it depends on where they go, with the layers and the topography. >> that is why they're getting the opportunity to hear more pings -- >> it would be like standing up on the mountains in the...

And it will paint a picture of the bottom with sound. anything that is plane debris will show up very bright. and it will be different than the local bottom structure in geology that is down there. and they will be able to id that. >> van, we're talking about signals coming from basically three miles from below the ocean. what can happen to the signals as they travel through water that deep? >> well, the way sound moves through water is very different from what we're used to on air and land. the different pressures and temperatures on air and land bend the sound waves into complex patterns. so...

Maximize the use of the tpl. the towed pinger locator is only good once the black boxes are pi pinging, once they stop, there is really no use. so while we have the potential of the black boxes to have battery life, maybe it is only a day or two but we still want to use that. once you get the bluefin in the water, the side scan sonar, there is really no limit for that. you can use that for an indefinite period. i would say there is really no rush to get that in. i know everyone wants to start getting you know, sonar pictures of the bottom, but if we take out the tpl now, we're really going to ...

Good while the black boxes are pinging. once they stop pinging, really it's of not much value. so we want to maximize that while we have potential for the black boxes to still have battery life. maybe it's another day or two, but we still want to use that. once you get the bluefin in the water, the side scan sonar, there is really no limit for that. you can use that for an indefinite period. i would say there is really no rush to get that in. i know everyone wants to start getting you know, sonar pictures of the bottom, but if we take out the tpl now, we're really going to give up the last cou...

That was as we turned around on that reciprocal course. but we are searching the entire area. it is just a matter of slowly and methodically doing that. you have to realize we are only moving at the pace a person can walk, so a couple of miles an hour. so you have this dimension of depth. so what is a miracle, the first hit we got, only up 300 meters -- so very shallow, once we heard it we lowered the tpl down to 400 meters, then really you want to get it at more like 3,000 meters. so we are searching the whole area, it is just a matter of slowly and methodically doing
