Plastic Bag Found at the Bottom of the World's Deepest Waters

Plastic bag found at depth of 36,000 feet

Man-made trash has sunk to new depths. A recent paper published in the journal Marine Policy details the staggering amount of plastic and other debris found at the bottom of the world's deepest ocean trench.

At least 3,000 pieces of litter, with some dating back 30 years, can be found in the Pacific Ocean's Mariana Trench.

This information was obtained by researchers combing through the Deep-sea Debris Database operated by the Global Oceanographic Data Centre of the Japan Agency for Marine-Earth Science and Technology (JAMSTEC).

This vast online catalogue, which launched for public use in March 2017, contains photos and videos of debris collected by deep-sea submersibles and remotely operated vehicles from more than 5,000 dives.

According to the paper, authored by JAMSTEC researchers, more than 33 percent of the observed debris is macro-plastic, of which 89 percent was single-use products. The deepest record is a plastic bag at 36,000 feet in the Mariana Trench.
