The Navy could take a census of whale populations by having sonar operators listen for whale farts. Sound travels really far over water but even farther in water. The ocean is obviously a very noisy place but the long term environmental affects of what's essentially a white noise machine are yet to be known.

lol, that's quite the sampling technique. Whatever works right? Must be a pretty characteristic sound, but what a job right. "What do you do for work?" "I analyze waveforms for whale flatulence"

The one I was replying to was talking about objectors in the mid-west. Not much ocean in Iowa :)
