The Great Pacific Garbage Patch, also described as the Pacific Trash Vortex, is a gyre of marine litter 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 concentrations of pelagic plastics, chemical sludge, and other debris that have been trapped by the currents of the North Pacific Gyre. Despite its size and density, the patch is not visible from satellite photography, since it consists primarily of suspended particulates in the upper water column. Since plastics break down to even smaller polymers, concentrations of submerged particles are not visible from space, nor do they appear as a continuous debris field. Instead, the patch is defined as an area in which the mass of plastic debris in the upper water column is significantly higher than average.

Famous quotes containing the words pacific, garbage and/or patch:
“Really, there is no infidelity, nowadays, so great as that which prays, and keeps the Sabbath, and rebuilds the churches. The sealer of the South Pacific preaches a truer doctrine.”
—Henry David Thoreau (1817–1862)
“But could a dream send up through onion fumes
Its white and violet, fight with fried potatoes
And yesterday’s garbage ripening in the hall,
Flutter, or sing an aria down these rooms
Even if we were willing to let it in,”
—Gwendolyn Brooks (b. 1917)
“Whatever patch of limb
he gazes on
with unblinking eyes,
I cover up
but I want him to see it all anyway.”
—Hla Stavhana (c. 50 A.D.)
