Marine scientists who studied crustaceans from three Pacific Ocean trenches, including the Mariana Trench, have discovered the depth of the influence of human activity on ocean ecosystems.

Other studies have shown elevated levels of industrial pollutants, including PCB and flame retardant, in these bottom dwellers.
