This is from a story that I've read a few times over the past several years. It's a story about these sonar detectors located deep in the ocean at a few different places. During the summer of 1997, these detectors detected a really loud, low frequency sound several times that is much louder than any known animal on earth can produce. Scientists speculate that the animal that can make such a loud noise must live in the deepest parts of the oceans and be much larger than a blue whale. I find this story really inspiring because it just makes my imagination go wild with possibilities of the things that could be creating this sound.
