#7599, "RE: Strange clicking heard--any ideas?" In response to In response to 7
I've heard that noises like that can be attributed to photoplankton. At night once, I scooped up a bucket full of water that had those glowing little guys. The bucket made a bunch of snap-crackle-pop kind of noises. So maybe its those little guys? But would have to be a lot of them for you to be able to hear it during the day.
