In order to also account for the larger, but more rare debris, they also overflew the patch in 2016 with a C-130 Hercules aircraft, equipped with LiDAR sensors. a series of large waves . Researchers were also looking at the impact of plastic on mesopelagic fish, such as lanternfish. Great Pacific Garbage Patch consists of items such as fishing nets containers, medical waste, plastic bottles and cans. Let us know if you have suggestions to improve this article (requires login). [57][59][60] 2009 data collected from Pacific albatross populations suggest the presence of two distinct debris zones. In 2015, the organization crossed the Great Pacific garbage patch with 30 vessels, to make observations and take samples with 652 survey nets. It is located roughly from 135°W to 155°W and 35°N to 42°N. The Great Pacific garbage patch, also described as the Pacific trash vortex is a garbage patch, a gyre of marine debris particles, in the central North Pacific Ocean cause. We did this after completing hundreds of scale model tests and a series of nearshore prototypes. 1986). [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. The Great Pacific Garbage Patch is located in the Pacific Subtropical Gyre. However, the Great Pacific Garbage Patch came to public attention only after 1997, when yachtsman Charles Moore, returning home after participating in the biennial Transpacific Race, chose a route that took him through the North Pacific subtropical gyre. [37][38] In fact, the Ocean Conservancy reported that China, Indonesia, Philippines, Thailand, and Vietnam dump more plastic in the sea than all other countries combined. The dimensions and depth of the patch are continuously changing. It is estimated that 1.15 to 2.41 million tonnes of plastic are entering the ocean each year from rivers. These air currents move in circular rotation which helps keep the garbage trapped. Despite the common public perception of the patch existing as giant islands of floating garbage, its low density (4 particles per cubic meter) prevents detection by satellite imagery, or even by casual boaters or divers in the area. PLASTIC ACCUMULATION. [48] It occupies a relatively stationary region of the North Pacific Ocean bounded by the North Pacific Gyre in the horse latitudes. The Great Pacific Garbage Patch … Moore alerted the oceanographer Curtis Ebbesmeyer, who subsequently dubbed the region the "Eastern Garbage Patch" (EGP). [21][22], At TEDxDelft2012,[23][24] Boyan Slat unveiled a concept for removing large amounts of marine debris from oceanic gyres. Will we rise to meet them? Because of the convergent nature of this Ekman flow, densities tend to be high in Transitional Water. The exact size of the patch is unknown, however, because it is constantly growing and moving. Scientists also estimate that 20 percent of the Great Pacific Garbage Patch’s volume of garbage is from the tsunami in Japan in 2011. "After entering the ocean, however, neuston plastic is redistributed by currents and winds. 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. It is due to the lack of large fish and the gentle breezes, fisherman rarely travel through the gyre that is bombarded with substantial levels of waste. [11] The area is frequently featured in media reports as an exceptional example of marine pollution. Here are the facts: About 80,000 metric tons of plastic objects occupy the patch. According to the researchers, the discarded plastics and other debris floats eastward out of countries in Asia from six primary sources: China, Indonesia, the Philippines, Vietnam, Sri Lanka and Thailand. Some people may think of a giant landfill when discussing “The Great Pacific Garbage Patch” but instead it is not garbage in the sense of a landfill. Some organisms thrive off discarded plastic, forming a new type of ecosystem called a "plastisphere". They estimate an 80,000 metric tons in the patch, with 1.8 trillion plastic pieces, out of which 92% of the mass is to be found in objects larger than 0.5 centimeters.[62][63][5]. 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. Every major ocean gyre has a garbage patch. Extrapolating from findings in the Sea of Japan, the researchers hypothesized that similar conditions would occur in other parts of the Pacific where prevailing currents were favorable to the creation of relatively stable waters.
