Popular Science: “Oceans are noisy places, but scientists aren’t always sure what’s making the hubbub. Enter an idea called GLUBS, or the Global Library of Underwater Biological Sound. Its genesis came about during the International Quiet Ocean Experiment—a project that aimed to coordinate the use of a worldwide network of non-military hydrophones to listen in on what was happening underwater. While GLUBS, in its fully realized form, doesn’t exist yet, a team of researchers is working on establishing a foundation from which it can be built. Passive acoustic monitoring—leaving a hydrophone running in the water—allows researchers to learn about life in the oceans through the complex orchestrations of sounds they hear…”
