In the summer of 1997, scientists recorded a strange, loud noise originating from an area west of Chile’s southern coast. They dubbed it “the bloop“. While searching for underwater volcanoes, researchers at the National Oceanic and Atmospheric Administration recorded the infamous loud, ultra-low frequency sound on hydrophones. These underwater microphones the US Navy originally developed
