on mars and the southern indian ocean is part of the high seas. it s way beyond the jurisdiction therefore it s in some of the least known parts of the pland. it can take pictures but not traditional type pictures. it uses, i guess it s sonar that is bumping around against things to take an image. it s like the way dolphins see with sound. they scan the area and visuallize. sonar images, they are pretty good. the resolution does not have the kind of fine resolution that the blue fin is providing but it has
they won t hear any more pings. so they have a relatively small area that this sub messible has to go back and forth to try to find some wreckage. they ll send the av down. in order to take sonar images of the bottom, you have to get close to the bottom. that s a fact. the av will drive down there and run a pattern. and it s limited. it s 16 square miles a day plus or minus. that s not exact. that s if everything works perfect. because two hours down, two hours back, four hours of downloading data, changing batteries, reprogramming the system, firing up the so this could take a few weeks at least. yes, every dive if they re lucky. exactly. the system is designed to come back. if it hits a problem, a depth it s not supposed to or hits something that tells it stop, come back up, it s not safe, it will come back up. the 16 hours could be 8 hours, 4 hours. it s not rocket science, but it
the operators of the system. if you have a very good sonar operator they will be able to pick out something natural against something man made against natural background, like this is a plane against a land slope. they talked in the press conference about the silt on the sea floor kauing a problem in terms of the transmission of problem. would this cause problem in terms of getting sonar images. nothing sonar discovergraph. any kind of coding, volcanic rock is tough, reflectings sound easily. it is cy to get lost in the rubble. a little sediment would be good. i don t think it will affect the sound much at all. everyone stay with us. we want the take another break. we will return at the top of the
that so far. and in any case, each detection sort of fills in a gap. fills in the box. and as they go back and forth in a very specific grid pattern they will start to build dots. and those dots will get tighter and tighter and you will get to a point where you can come to a very tight and close idea of where you would want to put that unmanned autonomous vehicle. and at that point you start to paint the ocean floor with sonar images. and if there is a wreckage there it will be quite obvious. now, miles what we see in australia is the larger map showing the search area, on the surface, the debris as it relates to where the pings were detected. on the close-up map, although it shows where the four pings were located and where they faded there is something missing from that map. what is missing from what the australian authorities are telling us? yeah, the thing about that map that is a little confusing
been so murky it s like exploring a dark room with a weak flashlight. with sonar they send sound down and it echoes and they turn it into digital images. this is the map, see this? this is the bow of the boat. you can look at the debris field. all of these marks are different parts of degree. and back here it s hard to see. this is the stern of the boat. want to show you more of the bow of the boat. they took not on the sonar images but they took 100,000 pictures with the underwater robots. the feeling is they can use this debris field and they can actually do it almost like an ntsb investigation of a plane crash on land and find out how it broke aparting with how it
