The stomach of a mahi mahi fish, caught by the crew, contained two small fish, three squid beaks and a large piece of vexar -- a plastic commonly used by the shellfish farming industry. The Great Pacific Garbage Patch is a collection of marine debris in the North Pacific Ocean. Marine debris can be very harmful to marine life in the gyre. Instead, pummeled by waves and broken down by sunlight, it fragments into tiny pieces -- known as microplastics. [54][55] While microplastics make up 94% of the estimated 1.8 trillion plastic pieces, they amount to only 8% of the 79,000 metric tons of plastic there, with most of the rest coming from the fishing industry. [15][16][17], In 2009, two project vessels from Project Kaisei,/ Ocean Voyages Institute; the New Horizon and the Kaisei, embarked on a voyage to research the patch and determine the feasibility of commercial scale collection and recycling. The Great Pacific Garbage Patch is located in the North Pacific Ocean. The collection of plastic and floating trash originates from the Pacific Rim, including countries in Asia, North America, and South America. They can get entangled in abandoned plastic fishing nets, which are being discarded largely due to inclement weather and illegal fishing. Made up of 80,000 metric tons of garbage, some estimate that the Great Pacific Garbage Patch is bigger than some U.S. states or even countries, but surmising the size is difficult due to the ocean’s currents and ever-changing winds. [66] Unlike organic debris, which biodegrades, plastic disintegrates into ever smaller pieces while remaining a polymer (without changing chemically). Allerdings lässt sich die tatsächliche Größe eines solchen Garbage Patches nur schwer erfassen. group of tissues that perform a specialized task. [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 description was based on research by several Alaska-based researchers in 1988 who measured neustonic plastic in the North Pacific Ocean. Ob das Projekt im zweiten Anlauf erfolgreicher sein wird, ist noch nicht absehbar. Why is Environmental Health Important to Humanity's Health? The Rights Holder for media is the person or group credited. The Great Pacific Garbage Patch is a concentration of marine debris in the North Pacific Ocean — the exact size and mass of which is unknown and difficult to measure. Instead, the size of the patch is determined by sampling. The overall concentration of plastics was seven times greater than the concentration of zooplankton in many of the sampled areas. chemical or other substance that harms a natural resource. Authors of the study wrote at the time, “Our results suggest that ocean plastic pollution within the GPGP is increasing exponentially and at a faster rate than in surrounding waters.”, In fact, even the Ocean Cleanup Project members were stunned by the size of the patch. According to Slat's calculations, a gyre could be cleaned up in five years' time, amounting to at least 7.25 million tons of plastic across all gyres. Wir sind keine Fremden, wenn es darum geht, Abfälle an Stränden und Gewässern zu sehen. Conserving natural resources is more important than ever. to determine the numeric value of something, often in comparison with something else, such as a determined standard value. 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. He hopes that by revealing what's going on "below the surface" he can "inspire people to stop using single-use plastic and to rethink the way we live. It can be easy to forget about pollution and landfills, so long as you don’t see it up close every day. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. [5], Researchers from The Ocean Cleanup project claimed that the patch covers 1.6 million square kilometers. Code of Ethics. The Great Pacific garbage patch, also described as the Pacific trash vortex, is a gyre of marine debris particles in the central North Pacific Ocean. [76][77] Twenty tons of plastic debris washes up on Midway every year with five tons ending up in the bellies of albatross chicks. It is located halfway between Hawaii and California. Denser debris can sink centimeters or even several meters beneath the surface, making the vortex’s area nearly impossible to measure. [27] He also advocated "radical plastic pollution prevention methods" to prevent gyres from reforming. area of the North Pacific Ocean where currents have trapped huge amounts of debris, mostly plastics. Appalled by the amount of trash he encountered on the high seas, he decided to dive into the garbage patch and share his swimmer's perspective with a global audience. Die genaue Größe dieser Plastikinseln lässt sich jedoch nur schwer abschätzen, da ein Großteil des Plastikmülls sich nicht an der Wasseroberfläche befindet, sondern darunter. [78] Fish and whales may also mistake the plastic as a food source. 1976; Nagata et al. According to. Researchers were also looking at the impact of plastic on mesopelagic fish, such as lanternfish. Similar dramatic increases in plastic debris have been reported off Japan. Our editors will review what you’ve submitted and determine whether to revise the article. object's complete turn around its own axis. Researchers found relatively high concentrations of marine debris accumulating in regions governed by ocean currents. The Great Pacific Garbage Patch is one of many areas in the ocean where marine debris naturally concentrates because of ocean currents. Fishermen shun it because its waters lack the nutrients to support an abundant catch. Dass in unseren Meeren unzählige Tonnen an Plastikmüll umhertreiben, wissen die meisten. The sturdiness of the Plastiki displayed the strength and durability of plastics, the creative ways that they can be repurposed, and the threat they pose to the environment when they don’t decompose. transportation of goods, usually by large boat. Gerät das Plastik zufällig in einen dieser Strudel, sammelt es sich darin an. Although microfibers are a source of plastic in the ocean, "we don't know how much it accounts for in terms of total marine plastic pollution," says Royer. The gyre is divided into two areas, the "Eastern Garbage Patch" between Hawaii and California, and the "Western Garbage Patch" extending eastward from Japanto the Hawaiian I… Approximately 8 million tons of plastic makes its way into the oceans each year. area where prevailing winds from different areas meet and interact. If a media asset is downloadable, a download button appears in the corner of the media viewer. Affected species include sea turtles and the black-footed albatross. Marine debris is litter that ends up in oceans, seas, and other large bodies of water. [34] This initial trial run of the Ocean Cleanup Project started towing its "Ocean Cleanup System 001" from San Francisco to a trial site some 240 nautical miles (260 miles) away. The team also collected, and counted, more than 43,000 plastic fragments using a "manta trawl" net -- a fine-meshed oceanographic instrument designed to skim the surface of the water to collect samples. degree or space to which a thing extends. Ben Lecomte says his face-to-face experience with the Pacific's garbage has prompted him to reduce his consumption of plastic. to know the outcome of a situation in advance. Many individuals and international organizations, however, are dedicated to preventing the patch from growing. The Great Pacific Garbage Patch stretches from the West Coast of North America to Japan. Make no mistake, the Great Pacific Garbage Patch is massive, so its size is not to be downplayed. According to the National Ocean Service, its name “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.” The NOS adds, “…much of the debris is actually small pieces of floating plastic that are not immediately evident to the naked eye.”. Royer is analyzing the seawater samples to better understand the geographical distribution of microfibers, and is examining the fish flesh to see if microfibers are lurking there. What kinds of plastic are accumulating there,'" he says.

Also called an alpha predator or top predator. Aus einem Greenpeace-Report geht hervor, dass rund 20 Prozent des Mülls von Schiffen, Booten und Offshore-Plattformen stammen.
