Submarine canyon plastic accumulation is driven by turbidity currents, simulation study shows

Plastic pollution is an ever-pressing concern for the health of our ocean ecosystems and their inhabitants, with estimates of over 10 million metric tons of plastic litter entering the marine realm each year. While evocative images often highlight surface plastics with organisms such as turtles and sea lions caught in fishing nets and plastic bags, the issue spans much deeper. In fact, during the exploration of the deepest part of the ocean (Mariana Trench) in 2019, a plastic bag was found at nearly 11,000 meters below sea level.
