sonars out there. and so if somebody is testing one of those, and turns it on for a short period of time, you would get a number of pings separated by a second. we need to know more about the signal, and then the search group in perth can figure out what to do with it. and also, people should know that there is a lot of ship traffic, and sea life in the southern indian ocean, and does it impact the ability to hear the pings? 37.5 kilohertz is a pretty frequency that is pretty clear in the ocean spectrum, however, there are dolphins that can make clicking sounds, and i believe 37.5 kilohertz is one of their frequencies, also, so perhaps the people at scripps ought to tell us about the sounds that dolphins can make. yes. and tell us about the equipment that is needed to hear the ping
aid that australia has known about this for several hours since it was lunchtime their time. you wonder why they didn t release anything. does that show that they themselves are skeptical about this? secondly, if it s not a pinger based on the fact that it is the exact frequency, the 3.75 that it needs to be or 37.5, rather that it needs to be. what else could it be? the process of cooperation takes time and it takes a lot of time to make sure that the information that they re disseminating is unequivocal and accurate. so what i do is i want to go back to this situation. i want to look at what we do know, which is that you rightry leaded to, 37.5. that is a unique signal and it appears to be in right part of the world. but let s interrogate the data to see why it necessarily couldn t be. and for me you don t get smoke without fire in these situations. so where is the debris field,
the black box, hoping to get much needed answers first. randi kaye, cnn, new york. announcer: this is cnn breaking news. all right. we re going to continue the conversation now. we ve got breaking news in from the chinese state news agency xinhua, that chinese patrol ship searching the area of the indian ocean has detected a pulse signal. a pulse signal. a pulse signal. that s as much as we know about this. so let s bring in an expert who can tell us more, simon boxwell, oceanographer with the nationalography center. let me ask you, simon, we re hearing this is a pulse signal with a frequency of 37.5 kilohertz per second in the indian ocean, does that mean anything to you? without hearing any more
shield and towed locater pinger. i m coming to michael kay, if we knew it had a black box detector it could deploy, had that been disclosed up to that point? that is a good question. the only assets i was aware of that had the ping locators were the echo and ocean shield. that has some very, very technical active and passive sonar equipment that if t has bn using. it might be the chinese ship had active or passive sonar that was listening to the 37.5 kilohertz pulse on. i m not sure you need a ping locator to be able to pick up that 37.5 kilohertz pulse. it is quite conceivable that a passive sonar could be able to do that. all right. i just want to give a question
maybe some sonar buoys on the water quickly. there should be a indication from the voice recorder. if the recorders are adjacent or near each other or reasonable proximi proximity, they should have detected two signals. let s get assets in the water in the area to corroborate before we get hopes up and disappoint families another time. it is the right number. 37.5 kilohertz, that s fantastic. it s the right number. what else could it be if not this pinger? what else at 37.5 kilohertz? give us an idea what else is out there that would be emitting that frequency? to our knowledge, to my knowledge, it is not a number, it is not a frequency that
