awblain:There were rumors that the French submarine Emeraude that went looking for AF447 couldn't really exploit its listening equipment to the full because while it was large, it didn't have much sensitivity at such high frequencies.
Do the Australian navy have ships with suitable big sonar to hand? They seem to
Leeuwin-class survey vessel - Wikipedia, the free encyclopedia but on the wrong side of the country. Looks like there should be room for some extra stuff onboard if the US has a special 40+ KHz sensitive device.
awblain, contact the Australians and get them to deploy this ship to the search area immediately! Use my name if you have to ... Actually, if this ship can paint a picture of the bottom of a 20,000 ft deep ocean, as well as that top of the line "Hummingbird" brand fish finder out of Eufaula, Alabama can paint the picture of the bottom of a typical lake (It's as if the lake is drained. You can see sunken boats and other features in detail), and I'll bet that it can, then they should deploy it. Maybe they haven't mapped that area yet, and they can kill two birds with one stone, by mapping the area, while reviewing the maps as they are scanned for the wreckage. That ship sounds totally bad ass for it's application. Thanks for sharing the info.
