Plastic pollution was first found in central gyres, or rotating ocean currents in which these observations from the Sargasso Sea were included in the 1972 Journal Science. In 1986, a group of undergraduate students conducted research by recording how much plastic they came across on their ship while traveling across the Atlantic Ocean.

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 ...
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.
Plastics entering the world's oceans have surged by an "unprecedented" amount since 2005 and could nearly triple by 2040 if no further action is taken, according to research published on Wednesday.
The gyre contains approximately six pounds of plastic for every pound of plankton. [17] A similar patch of floating plastic debris is found in the Atlantic Ocean, called the North Atlantic garbage patch.

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 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.
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.
