Answer: 
A friend of mine built a hydrophone then froze it into a lake - in north sweden. you can hear the results from here:

Maybe not THAT extreme, but I did bury my hydrophone in my compost pile. It's out on loan, but I figure I'd need to let it sit for a few days before recording with it, and then would need to do so for a few hours to see what I could get...the initial session was too short to get much cool stuff.
