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.
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.
The plastic data collected by the students at SEA validated Maximenko's model, and researchers were able to successfully predict plastic accumulation in the North Atlantic Ocean. [ 14 ] A recent study published in December 2022 investigated the microbial communities found in the North Atlantic Garbage Patch and compared the data to the Great ...
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 ...
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 ...
During the 5 Gyres expedition, 48 samples were taken from a 2,424 nautical sweep. The researchers found an increase in plastic pollution density, averaging 26,898 particles per square kilometer, but spiking at up to 396,342 particles per square kilometer, peaking near the center of the predicted accumulation zone, [4] with some estimates as high as one million particles per square kilometer.
The Indian Ocean Garbage Patch on a continuous ocean map centered near the south pole. The Indian Ocean garbage patch, discovered in 2010, is a marine garbage patch, a gyre of marine litter, suspended in the upper water column of the central Indian Ocean, specifically the Indian Ocean Gyre, one of the five major oceanic gyres.
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.
