Great Pacific garbage patch
The Great Pacific garbage patch, also described as the Pacific trash vortex, is a gyre of marine debris particles in the central North Pacific Ocean located roughly between 135°W to 155°W and 35°N and 42°N. The patch extends over an indeterminate area, with estimates ranging very widely depending on the degree of plastic concentration used to define the affected area.The patch is characterized by exceptionally high relative concentrations of pelagic plastics, chemical sludge and other debris that have been trapped by the currents of the North Pacific Gyre. Despite its enormous size and density (4 particles per cubic meter), the patch is not visible from satellite photography, nor is it necessarily detectable to casual boaters or divers in the area, as it consists primarily of a small increase in suspended, often microscopic particles in the upper water column.
