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.
The gyre contains approximately six pounds of plastic for every pound of plankton. [9] A similar patch of floating plastic debris is found in the Atlantic Ocean, called the North Atlantic garbage patch. [10] [11] This growing patch contributes to other environmental damage to marine ecosystems and species.
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 ...
The South Pacific garbage patch is an area of ocean with increased levels of marine debris and plastic particle pollution, within the ocean's pelagic zone. This area is in the South Pacific Gyre , which itself spans from waters east of Australia to the South American continent, as far north as the Equator , and south until reaching the ...
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 ...
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.
The Indian Ocean Gyre, located in the Indian Ocean, is, like the South Atlantic Gyre, bordered by the Intertropical Convergence Zone in the north and the Antarctic Circumpolar Current to the south. The South Equatorial Current forms the northern boundary of the Indian Ocean Gyre as it flows west along the equator towards the east coast of Africa.
The gyre contains approximately six pounds of plastic for every pound of plankton. [16] A similar patch of floating plastic debris is found in the Atlantic Ocean, called the North Atlantic garbage patch. [17] [18] This growing patch contributes to other environmental damage to marine ecosystems and species.
