So how about that noise coming from the Antarctic ice shelf?

>Unexpectedly, the researchers found that the pitch of the sound from the ice shelf changed when temperatures rose to above freezing and the ice began to melt. The sound waves began to slow down and the pitch dropped as a response. This was an indication of both melting and degree of melting. Once temperatures dipped below freezing again, the upper firn refroze but did not regain the initial pitch it had before the firn melted.

It's quite good humans finally learned to recognize that vibration can have a source and source is in way observed by vibrations.
