robot arriving at the search zone for the missing titanic submersible. the mission to find the five people on board critical juncture as experts warn the air supply may run thought a matter of minutes. todd piro joins us with the latest. todd: the coast guard is leading the international effort to find the five passengers on board who to your point are expected to run out of oxygen just minutes from now at 7:08 eastern time that literally is seven minutes from right now. officials are unsure if those reported under water banging noises are a sign of life. we don t know what they re. it s inconclusive. the important pieces we are searching in the area where the noises were detected. todd: the search now expanded to over 2.5 miles below the surface with more vessels and special equipment joining. in crews also surveys over 14,000 square miles twice the size of the state of kentucky cut. we are learning more about the history of ocean gates expedition with reports one pass
area is the size of new england right now. ainsley: stockton rush is the ceo. i m sorry, go ahead. pete: let s say it was them knocking, why would you be able to identify the noise but not be able to locate or geo locate? what is it about the technology that allows you to hear it but not find it? so, there is levels of water, temperature gradients in the ocean and they tend to do a really good job of keeping sound waves at one level. so, they may be able to see it or may be able to hear it but they can t find it because the levels of the water are all different. it s the same reason they are able to hide a russian submarine in a couple layers of water and we can t find it. same reason everything is quiet. the big problem you have is it s extremely quiet. even if they are banging, the noise isn t great enough to find it. ainsley: jake, i know they were only supposed to be down
worse with hot weather in the forecast the next few days. wildfires have killed nine people and destroyed 1,000 homes in the last few months. the fires are having an impact on the beloved call las as well. th water. a few days left, leaders in sydney are saying the iconic fireworks show will go on as scheduled. a quarter million signed a petition demanding that the show be canceled. they said the fireworks fund could have been spent fighting the fire. you heard that report at the beginning of the segment saying the fires were creating their own weather. can you explain that. . yeah. hi, garrett. thanks for having me. it is pretty straightforward and close to what s happening with the climate system generally. whether it s based on temperature gradients, the differences between hot and cold. when you have fires this big, it
15 of the 30 some-odd bodies. difficult to know where they are. possible many of them are still strapped into their seats. the dimpb rfference between the sampson and the fort worth? the sampson is designed for anti-warfare. the fort worth is the smallest ship we have in the nation in terms of combatants. and it s a new class. completely different type of ship, different capabilities. these black boxes, they have these pingers and they have batteries, they ll go for another 20 21 22 days before all of a sudden they go silent. that s right. but you have to be nearby in order to hear that ping right? you have to be somewhat close by. sound in the water can actually travel pretty far based on the temperature gradients and the currents. sound can go pretty far. it s not about being over top of it. it depends on the characteristics of the seas underneath the surface.
used by bringing in more evidence on the radar tracking of this aeroplane. and the location is exactly on this track that the ships were told to go and have a look at. so there s some supporting evidence that, yes, they are the black boxes. we listened to this press conference live from angus houston, paul. you were optimistic about this, but now cnn is hearing that the frequency detected was 33.3 kilohertz, not 37.5. do you still believe that these are, in fact, the pingers, and is it an exact match? is 33 that close to 37? okay, we re talking about 10%. and we had a discussion this evening before air about the effects of temperature gradients on the transmission of different signals through water and the effects that can have with respect to frequency of signals.
