Garbage patch pacific ocean wiki
While "Great Pacific Garbage Patch" is a term often used by the media, it does not paint an accurate picture of the marine debris problem in the North Pacific ocean. Marine debris concentrates in various regions of the North Pacific, not just in one area. The exact size, content, and location of the "garbage patches" are difficult to accurately predict. The name "Pacific Garbage Patch" has led many to believe that this area is a large and continuous patch of easily visible marine debris items such as bottles and other litter—akin to a literal island of trash that should be visible with satellite or aerial photographs.
This is not the case. While higher concentrations of litter items can be found in this area, much of the debris is actually small pieces of floating plastic that are not immediately evident to the naked eye.
Ocean debris is continuously mixed by wind and wave action and widely dispersed both over huge surface areas and throughout the top portion of the water column. These dangers are compounded by the fact that plastics both leach out and absorb harmful pollutants.
As plastics break down through photodegradation, they leach out colorants and chemicals, such as bisphenol A BPA , that have been linked to environmental and health problems. Conversely, plastics can also absorb pollutants, such as PCBs, from the seawater. These chemicals can then enter the food chain when consumed by marine life.
Many individuals and international organizations, however, are dedicated to preventing the patch from growing. Cleaning up marine debris is not as easy as it sounds. Many microplastics are the same size as small sea animals, so nets designed to scoop up trash would catch these creatures as well. Even if we could design nets that would just catch garbage, the size of the oceans makes this job far too time-consuming to consider. Many expeditions have traveled through the Great Pacific Garbage Patch.
Charles Moore, who discovered the patch in , continues to raise awareness through his own environmental organization, the Algalita Marine Research Foundation. During a expedition , Moore and his team used aerial drones, to assess from above the extent of the trash below. The drones determined that there is times more plastic by weight than previously measured.
The team also discovered more permanent plastic features, or islands, some over 15 meters 50 feet in length. Scientists and explorers agree that limiting or eliminating our use of disposable plastics and increasing our use of biodegradable resources will be the best way to clean up the Great Pacific Garbage Patch. Organizations such as the Plastic Pollution Coalition and the Plastic Oceans Foundation are using social media and direct action campaigns to support individuals, manufacturers, and businesses in their transition from toxic , disposable plastics to biodegradable or reusable materials.

Fishermen shun it because its waters lack the nutrients to support an abundant catch. Sailors dodge it because it lacks the wind to propel their sailboats. In the week it took to cross the subtropical high, no matter what time of day I looked, plastic debris was floating everywhere: bottles, bottle caps, wrappers, fragments. Months later, after I discussed what I had seen with the oceanographer Curtis Ebbesmeyer, perhaps the world's leading expert on flotsam, he began referring to the area as the 'eastern garbage patch.
Strange Cargo When ships are caught in storms, they often lose cargo to the oceans. The following are just a few of the strange items that have washed up on shores:.

From massive marine mammals like whales to the tiny krill that form the bottom of the food chain, all life in the ocean is interconnected. While the ocean seems vast and unending, it is, in fact, finite; as the climate continues to change, we are learning more about those limits.
Explore these resources to teach students about marine organisms, their relationship with one another, and with their environment. Whether a description of a keystone species or the impact of the Pacific garbage patch, these articles provide insight into a breadth of important issues facing our world today, including the environment, civic engagement, and history.
Plastic is ubiquitous in our everyday lives. Some plastics we can reuse or recycle—and many play important roles in areas like medicine and public safety—but other items, such as straws, are designed for only one use. In fact, more than 40 percent of plastic is used only once before it is thrown away, where it lingers in the environment for a long, long time.
It often breaks down into smaller and smaller particles, called microplastics, which can be ingested by both animals and people. Fortunately, there are things we can do to help—like stop using plastic bags, straws, and bottles, recycling when we can, and disposing of waste properly. Use these classroom resources to teach about ocean plastics and check back for more coming later this year! Use this idea and suggested resources to build the perfect lesson or activity on plastic pollution and ocean circulation for your classroom.

Encyclopedic Entry Vocabulary. The Great Pacific Garbage Patch is a soupy collection of marine debris—mostly plastics.
Worldwide Garbage Patches. The Atlantic and Indian Oceans both have trash vortexes. Even shipping routes in smaller bodies of water, such as the North Sea, are developing garbage patches. The following are just a few of the strange items that have washed up on shores: In , five shipping containers of Nike sneakers and work boots were lost to the Pacific in a storm. People in Washington and Oregon snatched up the shoes on shore, holding swap meets to find matched pairs to wear or sell.
In , rubber duckies floated in the Pacific when a ship lost tens of thousands of bathtub toys. The ducks were accompanied by turtles, beavers, and frogs. In , a ship lost 34, pieces of hockey gear, including gloves, chest protectors, and shin guards.
