According to a new study, the eerie 3.5-second recording that was picked up by an autonomous vehicle deep in the Mariana Trench is a new type of baleen whale call that no one has ever heard before, and it’s still not clear what it actually means. The same sound was recorded on multiple occasions from autumn 2014 to spring 2015 in the Marianas Trench Marine National Monument - a 246,000 km2 (94,981 mile2) part of the Mariana Trench east of Guam, and one of the largest marine protected areas in the world. But it's not inaccessible to … The dive to the ocean’s deepest point turned up some surprises.

[We] hypothesise that these complex sounds were produced by a biological source.". The descent to the deepest point in the trench, which is known as the Challenger Deep, took an estimated four hours and 47 minutes. In 2012, director James Cameron set a record exploring the Mariana Trench alone, with a record depth of 10,898 meters. The Trench is technically U.S. territory, but since a giant, super-deep ocean hole that contains all sorts of strange ecosystems is obviously fairly vulnerable to human tampering, President George W. Bush declared it a “marine national monument” in 2009. The maximum known depth is 10,984 metres (36,037 ft) (± 25 metres [82 ft]) (6.825 miles) at the southern end of a small slot-shaped valley in its floor known as the Challenger Deep. 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. The Mariana Trench was first pinpointed and surveyed in 1951 by the British Survey ship Challenger II., which gave its name for the trench's deepest point, "The Challenger Deep".

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 Mariana Trench was created by the process that occurs in a subduction zone, where two massive slabs of oceanic crust collide. Given its unique geographic features, the Mariana Trench presents several factors that make it hard for life to exist. According to a new study, the eerie 3.5-second recording that was picked up by an autonomous vehicle deep in the Mariana Trench is a new type of baleen whale call that no one has ever heard before, and it’s still not clear what it actually means.
