half and that apparently it has a pulse signal of 37.5 a kilohertz, what is what s encouraging to you about this information? well, that s encouraging, because that s the secret number for the frequency for the black box pingers, and the rep rate was about right, meaning it makes that noise about every second. the idea it was only heard a short bit, i kind of get that the water depth of that area goes from shallower than 2,000 meters, less than a mile and a half, to greater than 5,000 meters which is about three miles. depending on where it is inside there, i could see that the signal could come and go, depending where they are with the boat. so there s nothing, you know, that s like out of place. it s just waiting to make sure that that s really what was heard yesterday. or today. your feeling, there are a lot of potential obstructions down below, that if indeed this was
black box. mol molly henneberg is live in d.c. they are saying the chinese ship tee ployed a black box detector into the water in the southern indian ocean and picked up a pulse signal, a ping over time at 37.5 kilohertz, the same frequency emitted by the flight data recorders. the chinese say one of their air force planes spotted white floating objects in that search area. malaysian authorities are trying to verify this report. it s coming from the sources, the chinese state-run media. military planes and ships from several nations are scouring parts of the indian ocean where the plane may have gone down. there is some real skepticism about this ping, right? absolutely. because it came from the chinese state-run media, reports from
we have our resources around the world in kuala lumpur and perth. simon boxall joining us and mary schiavo. we will continue to report on the breaking news reported by the chinese news agency xinhua, that the patrol ship discovered a pulse signal of 37.5 kilohertz that would match a flight data recorder. it has not been confirmed to have come from a flight data recorder. stay here with cnn. we will continue with the coverage in just a moment. hi she s a dietitian. and back when i wasn t eating right, she got me drinking boost. it s got a great taste, and it helps give me the nutrition i was missing. helping me stay more like me.

is the bluefin detector. we know they are looking for the black box, the flight data recorder and the cockpit voice recorder. this is possibly the last day. we are in the last few hours that they believe this pinger would continue to emit a signal of any kind because it is 30 days in. secondly, again, this is coming from xinhua, the state news agency in china, they detected a pulse signal, but it has a frequency of 37.5 kilohertz. that is, we do know, the standard beacon frequency. however, a couple of things we did not know, one, we did not know that there was a black box detector on this ship. we were only told of the two black box detectors deployed today from the two other ships that we know of.
the debris is found. and do you believe the chinese report sths. i am treating them with extreme caution. why? for all of the reasons that we are talking about today, because it has not come from the official sources or the j.a.c.c. and it has not been corroborated and the equipment that was used to actually discover the pings, i would say it is suboptimal and certainly looking at the equipment out there on the ocean shield, and the echo, and active and passive sonar echo systems with filtering. and we know in that part of the world, there is a lot of background noise, and so to detect that 37.5 kilohertz ping is difficult. we want to make sure it is that and not background noise, so there are a number of factors the corroborate before we start to release any information to the indicate that it is from flight 370. and richard, how do you confirm it in any way or do the
