Sounds of Enceladus

The Cassini Magnetometer team has released this plot showing ion cyclotron waves during the February 17 Cassini flyby of Enceladus. Actually, the caption for this release has very little to do with the plot and much more to do with the Quicktime audio file released with this image. The audio file, which I have yet to listen to, "shows the power of these waves near Enceladus". The caption says that these ion cyclotron waves in Saturn's magnetosphere provide information on the types of ions present in Cassini's environment. Based on other release, like the CDA release mentioned below, it appears these come from water ions.
