I have more good news to report in the search for Malaysia Airlines Flight MH370.
CNN is reporting this morning that an Australian P3 Orion has picked up signals during Thursday’s search from some of the 84 sonobuoys that were dropped into ocean in the vicinity of the location where the Ocean Shield picked up signals from the black boxes with the towed pinger locater (TPL).
Sonobuoys, which float on the surface, dangle a hydrophone (i.e., an underwater microphone) attached to a 1,000 foot cable. The sonobuoy broadcasts any radio signal picked up by the hydrophone.
Searchers are using the sonobuoys to precisely locate the black boxes on the ocean bottom, which is 14,800 feet deep.
The electronic information picked up by the sonobuoys will be evaluated Thursday night.
Depending on the results, the Ocean Shield may deploy the Bluefin 21 to find the wreckage and and photograph it.
