The patch is located from 22°N to 38°N and its western and eastern boundaries are unclear. [5] The debris zone shifts by as much as 1,600 km (1,000 mi) north and south seasonally, and drifts even farther south during the El Niño-Southern Oscillation, according to the NOAA. [3]
The North Pacific Garbage Patch on a continuous ocean map. The Great Pacific Garbage Patch formed gradually as a result of ocean or marine pollution gathered by ocean currents. [39] It occupies a relatively stationary region of the North Pacific Ocean bounded by the North Pacific Gyre in the horse latitudes. The gyre's rotational pattern draws ...
A garbage patch is a gyre of marine debris particles caused by the effects of ocean currents and increasing plastic pollution by human populations. These human-caused collections of plastic and other debris are responsible for ecosystem and environmental problems that affect marine life, contaminate oceans with toxic chemicals, and contribute ...
After sampling water sites around the country, the Surfrider Foundation, an ocean protection advocacy organization, found unsafe levels of fecal contamination at 19% of the 9,095 water samples. Of ...
The images show what various parts of the country looked like before the air and water protections that exist today. Vintage photos taken by the EPA reveal what America looked like before ...
Information included in the Atlas includes accurate, seamless maps, documentation, and geospatial data that crosses political borders. This data is displayed as series of interactive map layers in an easy to use map viewer format. Most layers in the North American Environmental Atlas are at a scale of 1:1:10,000,000 or finer.

While marine pollution can be obvious, as with the marine debris shown above, it is often the pollutants that cannot be seen that cause most harm.. Marine pollution occurs when substances used or spread by humans, such as industrial, agricultural and residential waste, particles, noise, excess carbon dioxide or invasive organisms enter the ocean and cause harmful effects there.
Red tides in the Gulf of Mexico and toxic blue-green algae in inland waters are killing animals and stoking outrage in South Florida.
