There could be as much plastic as fish in the sea. [124] It has a very high level of plastic particulate suspended in the upper water column. In samples taken from the North Pacific Gyre in 1999, the mass of plastic exceeded that of zooplankton (the dominant animal life in the area) by a factor of six. [1] [116]
Plastic in rivers can be more easily trapped at the source but that accounts for only a part of all plastic in the oceans. In 2022, the organization collected 923,000 kg of ocean and river plastic with the expenses of €45.603 million; a cost of €49.4/kg. [1] In 2023 the efficacy has significantly improved due to the upscaling of the river ...
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.
Long-term changes in plastic meso-litter have been reported using surface net tows: in the North Pacific Subtropical Gyre in 1999, plastic abundance was 335,000 items per square kilometre (870,000/sq mi) and 5.1 kilograms per square kilometre (29 lb/sq mi), roughly an order of magnitude greater than samples collected in the 1980s.
It is approximated that there is a stock of 86 million tons of plastic marine debris in the worldwide ocean as of the end of 2013, assuming that 1.4% of global plastics produced from 1950 to 2013 has entered the ocean and has accumulated there. [44] Global consumption of plastics is estimated to be 300 million tonnes per year as of 2022, with ...
A baby sea turtle that washed ashore in Florida and later died was found to have 104 pieces of plastic in its stomach upon examination. A baby sea turtle that washed ashore in Florida and later ...

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 ...
