listen sounds from the black boxes beacons amazeme
The Ocean Shield has been dragging a U.S. Navy device called a towed pinger locator through the water to listen for any sounds from the black boxes' beacons. Over the past 10 days, the equipment has picked up four separate signals.
The Bluefin sub takes six times longer to cover the same area as the ping locator, and the two devices can't be used at the same time. Crews were hoping to detect additional signals before sending down the sub, so they could triangulate the source and zero in on where exactly the black boxes may be.
But it has been 38 days since the plane disappeared, and search crews haven't picked up any new sounds since Tuesday, suggesting that the devices' batteries may now be dead. That is why officials will now begin using the Bluefin, Houston said.
The submarine will take 24 hours to complete each mission: two hours to dive to the bottom, 16 hours to search the seafloor, two hours to return to the surface, and four hours to download the data, Houston said. In its first deployment, it will search a 40-square-kilometer (15-square-mile) section of seafloor.Obama target further costs Ukraine council private pool of savings Japan expected economic negotiated Broader deal pact Negotiations tariffs Sino-Japan ties call improving public troops Osama telling self actions Putin Russia polling wins people respect Taj complex art quite intact Perth Ledger Peter Pan leave the world alone ����ѩ��self protection
