At the ocean surface, plastic debris is concentrated within circular structures of large areal extent, called ocean gyres. Ocean gyres form within all oceans, due to alternating patterns of zonal winds that drive equatorward interior transport in the subtropics, and poleward interior transport in subpolar oceans.
A garbage patch is a gyre of marine debris particles caused by the effects of ocean currents and increasing plastic pollution by human populations. These human-caused collections of plastic and other debris are responsible for ecosystem and environmental problems that affect marine life, contaminate oceans with toxic chemicals, and contribute ...
Great Pacific Garbage Patch in August 2015 (model) The patch is created in the gyre of the North Pacific Subtropical Convergence Zone. The Great Pacific Garbage Patch (also Pacific trash vortex and North Pacific Garbage Patch [1]) is a garbage patch, a gyre of marine debris particles, in the central North Pacific Ocean.
This is an accepted version of this page This is the latest accepted revision, reviewed on 11 December 2024. Large floating field of debris in the North Atlantic Ocean The North Atlantic Gyre is one of five major ocean gyres. The North Atlantic garbage patch is a garbage patch of man-made marine debris found floating within the North Atlantic Gyre, originally documented in 1972. A 22-year ...
An estimated 171 trillion plastic particles were afloat in the oceans by 2019, according to peer-reviewed research led by the 5 Gyres Institute, a U.S. organisation that campaigns to reduce ...
Marine debris, also known as marine litter, is human-created solid material that has deliberately or accidentally been released in seas or the ocean.Floating oceanic debris tends to accumulate at the center of gyres and on coastlines, frequently washing aground, when it is known as beach litter or tidewrack.
The United States National Academy of Sciences estimated in 2022 that the worldwide entry of plastic into the ocean was 8 million metric tons of plastic per year. [63] A 2021 study by The Ocean Cleanup estimated that rivers convey between 0.8 and 2.7 million metric tons of plastic into the ocean, and ranked these river's countries. The top ten ...
Saving the planet's oceans from plastic pollution isn't on the agenda of a typical 12-year-old -- however, Anna Du is working to achieve just that. 12-year-old engineer invents device to combat ...
