this may sound a little unsettling. but do you know that we as a human race have more information about the mapping of mars than we do about our own oceans? it s true. we re about at the 5% mark when it comes to our oceans. and chad myers joins me now to answer questions about that. a., why. and b., what do we know and what don t we know. why is because you can t take a picture from a satellite of the ocean floor and get the up and down. get the canyons. you just can t see through the ocean far enough. so how do we get that data? we have a pinger on a ship, and the ship moves along. well, the pinger, just like a fish finder, finds the bottom. depending on how far away the bottom is, that s about a mile
this is not going to show up on some random fish-finder, you know, from some bertram going across fishing in the area. who has a receiver to hear these pings? well, agencies such as the navy, coast guard, et cetera, typically, can pick up on the signal, can either be done on the surface or by a towed array at a certain depth. how many receivers do you think are out there listening for a ping right now? is there any way to put a number on that? oh, gosh. ten, a dozen, a hundred? i can only speculate. i honestly don t know. okay. that s a fair answer because we don t know either. don, if it has to be an official boat, it would be great if we could put some kind of receiver on every little fishing vessel out there, not a ten-foot sciff. i get that but then we would be able to really cover some ground.
mr. scofield, stand by. our meteorologist, chad myers, has been reporting on this, also, the tracking of the plane, satellite, radar and all that. do you have any questions for him? chuck, i do. this is not going to show up on some random fish-finder, from some bertram going across fishing in the area. who has a receiver to hear these pings? agencies such as the navy, coast guard, et cetera, typically, can pick up on the signal, be done on the surface or by a toe da ray at a certain depth. how many receivers do you think are out there listening for a ping right now. is there any way to put a number on that? ten, a dozen, a hundred. i honestly don t know. that s a fair answer. we don t know either. don, if it has to be an official boat, it would be great if we
alert. yes, sir. we are almost at mount. delta 172, heavy, traffic. 12:00, 1400 feet, 1600 feet. okay. we have them on the fish finder here. the fish finder is an on board collision avoidance radar. retired captain tom casey. that s close. that s close for anybody. they are looking at a 747 coming at him. that s a large footprint in the air. earlier in year, the inspector general said it had jumped 50% in 2009 and 2010. that s mostly because controllers are encouraged to self-report without penalty to identify safety concerns. controllers have to be on their game, making sure that traffic is separated. and it takes a lot of coordination between controllers at each of the facilities. the faa says it will dissect this entire case to learn from it and make sure it doesn t
