A recent study on deep-sea ocean pollution identified the bag, found in 1998 by a robotic submersible at a depth of 35,756 feet in the Mariana Trench, as the deepest known piece of plastic trash on Earth. The Challenger Deep is a relatively small slot-shaped depression in the bottom of a considerably larger crescent-shaped oceanic trench, which itself is an unusually deep feature in the ocean floor. While these sounds are entirely unique in the scientific record, the best clue Nieukirk's team had for identifying them was an equally bizarre recoding from 2001, made in Australia’s Great Barrier Reef: Known as the minke whale 'Star Wars' call, it sounds just as alien as this more recent recording, and the researchers say that based on similarities of frequency and structure, the Western Pacific Biotwang likely comes from the same type of animal.
