Marine debris is litter that ends up in oceans, seas, and other large bodies of water. Some organisms thrive off discarded plastic, forming a new type of ecosystem called a "plastisphere". It Presents a Significant Danger to Marine Mammals. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. A Gyre is a system of circulating currents in an ocean, caused by the Coriolis Effect. Instead, the size of the patch is determined by sampling. She previously worked on the Britannica Book of... Human action has triggered a vast cascade of environmental problems that now threaten the continued ability of both natural and human systems to flourish. They specifically indicated the North Pacific Gyre. The garbage patch is not one solid mass of trash, but consists of countless tiny islands that come together … [72] Approximately one-third of their chicks die, and many of those deaths are from plastic unwittingly fed to them by their parents.

Articles from Britannica Encyclopedias for elementary and high school students. However this leads to gyres attracting the rubbish towards the middle which leads to rubbish patches such as the Great Pacific Garbage Patch. The GPGP is a huge swirling mass of plastic in the middle of the Pacific Ocean, just above the Hawaiian . Solving the critical environmental problems of global warming, water scarcity, pollution, and biodiversity loss are perhaps the greatest challenges of the 21st century. Half of the Great Pacific Garbage Patch is made of ghost nets, fishing nets, and ropes that are discarded because of the fishing activity around that specific area. If you dragged the Great Pacific Garbage Patch onto dry land, how much territory would it … [39] China alone is responsible for 30% of worldwide plastic ocean pollution. In general scientists were not able to calculate the impact on the entire food chain however, it is clear that the garbage moves up in the food chain … The majority of this debris—about 705,000 tons—is fishing nets. The Great Pacific Garbage Patch, also known as the Pacific trash vortex, spans waters from the West Coast of North America to Japan. In this way, the plastic is transported from high-density areas to low-density areas. This is not the case. If it were, developers might well be selling beachfront homes, promoting it as an exciting opportunity to live on a brand-new, man-made island. The Gyre is a spiral of currents created by a system of air currents. The survey found that, although the patch contains large pieces, it is on the whole made up of smaller items that increase in concentration toward the gyre's centre, and these 'confetti-like' pieces that are visible just beneath the surface suggests the affected area may be much smaller. The Great Pacific Garbage Patch is not, as popularly portrayed, a solid mass of floating waste somewhere in the middle of the ocean. A general overview is provided in Dautel, Susan L. "Transoceanic Trash: International and United States Strategies for the Great Pacific Garbage Patch", 3 Golden Gate U. Envtl. Visual comparison of weight of trash in Great Pacific Garbage Patch compared to that of U.S. CO2 emissions. The exact size of the patch is unknown, however, because it is constantly growing and moving. When I first heard about The Great Pacific Garbage Patch (TGPGP), I imagined an island of trash floating aimlessly in some remote area of the Pacific—but as I found out, that image is flawed. In September, we launched our first system, with the aim of achieving proof of technology and commencing cleanup. [5] The patch is believed to have increased "10-fold each decade" since 1945. But from now on, I can sum it all up in one simple phrase: the Great Pacific Garbage Patch. 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. It is located roughly from 135°W to 155°W and 35°N to 42°N. The Great Pacific Garbage Patch stretches from the West Coast of North America to Japan. In the North Pacific Ocean, there is a gyre that has caused such a drastic collection of debris that it has earned the name The Great Pacific Garbage Patch. Approximately 80% of the debris comes from Asia and Northern America. What is the Great Pacific Garbage Patch? And it’s not ocean going vessels that are to blame for all this plastic: scientists have concluded that 80% of marine plastic is from land. It is made up of two parts. 181 (2007). [40] Efforts to slow land generated debris and consequent marine debris accumulations have been undertaken by the Coastal Conservancy, Earth Day, and World Cleanup Day. It is located roughly from 135°W to 155°W and 35°N to 42°N. The GPS Tracker technology is being combined with satellite imagery increasing the ability to locate plastic trash and ghostnets in real time via satellite imagery which will greatly increase cleanup capacity and efficiency. [4] Some of the plastic in the patch is over 50 years old, and includes items (and fragments of items) such as "plastic lighters, toothbrushes, water bottles, pens, baby bottles, cell phones, plastic bags, and nurdles." It is estimated that 1.15 to 2.41 million tonnes of plastic are entering the ocean each year from rivers. [6] A similar patch of floating plastic debris is found in the Atlantic Ocean, called the North Atlantic garbage patch. [2] The gyre is divided into two areas, the "Eastern Garbage Patch" between Hawaii and California, and the "Western Garbage Patch" extending eastward from Japan to the Hawaiian Islands. ... A crew will now perform new tests and collect additional data to explore the root cause … all of Texas. The Great Pacific Garbage Patch (GPGP) is the largest of the five offshore plastic accumulation zones in the world’s oceans. Garbage that reaches the ocean from the west coast of the United States and from the east coast of Japan is carried by currents—including the California Current, the North Equatorial Current, the North Pacific Current, and the Kuroshio—into the North Pacific subtropical gyre, the clockwise rotation of which draws in and traps solid matter such as plastics. The great Pacific garbage patch causes great harm to the environment. [55], The size of the patch is indefinite, as is the precise distribution of debris because large items are uncommon. The Great Pacific Garbage Patch is caused by the North Pacific Tropical Gyre. The Great Pacific Garbage Patch is a great big pool of debris that has undoubtedly caused some … The "Great Garbage Patch" in the Pacific is 200 times smaller than previously claimed, according to scientists. The Great Pacific garbage patch formed gradually as a result of ocean or marine pollution gathered by ocean currents. [27], The 2012 Algalita/5 Gyres Asia Pacific Expedition began in the Marshall Islands on 1 May, investigated the patch, collecting samples for the 5 Gyres Institute, Algalita Marine Research Foundation, and several other institutions, including NOAA, Scripps, IPRC and Woods Hole Oceanographic Institute. 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. [56] Most debris consists of small plastic particles suspended at or just below the surface, evading detection by aircraft or satellite. The Great Pacific Garbage Patch is located in the Pacific Subtropical Gyre. This was an environmentalist scare that became a bit of a … It takes years for debris to travel from the coasts to the gyre, and, as it is carried along, photodegradation causes the plastics to break down into tiny, nearly invisible bits. [11][68][69] Plastic attracts seabirds and fish. In 2012, the Sea Education Association (SEA) conducted research expeditions in the gyre. The continent of Asia (blue) represents U.S. CO2 emissions in 2014, covering an area approximately 295 times larger than the state of Georgia (green), which represents the amount of trash in the Great Pacific Garbage Patch.
