Mariana Trench Sound

The Mariana Trench, which lies between Japan to the north and Australia to the south, features depths in excess of 36,000 feet, and is currently the deepest known part of the Earth’s oceans. Scientists at OSU’s Hatfield Marine Science Center detected a strange booming sound heard in the the deepest part of the ocean, and called i the “Western Pacific Biotwang”. The mysterious five-part call lasts between 2.5-3.5 seconds, and includes frequencies as low as 38 hertz. It was recorded using passive acoustic ocean gliders, or instruments that traverse the ocean autonomously, and can dive up to 1,000 meters.
