[microsound] hydrophones and methane

[Michael Palace]

Okay,

I've talked with my collaborator and I'll try to get some preliminary 
data out to you all.

Files will be 2 Gb Mp3 files.  We use zoom h4 with some hydrophones to 
sample over many days.  the zoom makes a new file ever 2 gb so when 
running continuously we can get about 24 days without have to visit the 
instruments.

Initial deployment was in a fen in New Hampshire and on a lake in 
Sweden.  I'll have more next week and the mp3 files.
