The Great Pacific Garbage Patch, also known as the Pacific trash vortex, is a gyre of marine debris particles in the central North Pacific Ocean. It is located between California and Hawaii. The patch was discovered by Charles Moore in 1997 while sailing from Hawaii to California. The patch is believed to have increased 10-fold each decade since 1945 and is the largest accumulation of ocean plastic in the world. It is important to note that the patch is not a solid mass of plastic but rather a dispersed area consisting primarily of microscopic particles in the upper water column, known as microplastics. These microplastics account for 94% of the estimated 1.8 trillion pieces of plastic in the patch.

What You'll Learn
The Great Pacific Garbage Patch is not a floating island
The Great Pacific Garbage Patch (GPGP), also known as the Pacific Trash Vortex, is a gyre of marine debris particles in the central North Pacific Ocean. It is not a floating island of plastic as is commonly believed. Rather, it is a widely dispersed area consisting primarily of "fingernail-sized or smaller"—often microscopic—particles in the upper water column known as microplastics.
The GPGP is the largest accumulation of ocean plastic in the world and is located between Hawaii and California. It covers an estimated surface of 1.6 million square kilometres, with a low density of 4 particles per cubic metre. This low density prevents detection by satellite imagery or even by casual boaters or divers in the area. The patch is a collection of marine debris that has accumulated due to ocean currents, with plastic and floating trash originating from countries in Asia, North America, and South America.
The name "Pacific Garbage Patch" has led to the misconception that it is a large and continuous patch of easily visible marine debris, akin to a literal island of trash that should be visible from space. However, this is not the case. The plastic pollution in the GPGP is scattered and does not form a solid mass, with buoyant plastic distributed within the top few meters of the ocean. While larger pieces of plastic resurface more rapidly, the microplastics that dominate the area are often microscopic and cannot always be seen by the naked eye.
The GPGP has serious ecological implications. Floating at the surface of the patch is 180 times more plastic than marine life, and animals migrating through or inhabiting this area are likely consuming plastic. For example, sea turtles caught in fisheries within and around the patch can have up to 74% of their diets composed of ocean plastics. Additionally, fishing nets account for 46% of the mass in the GPGP, posing a danger to marine life that cannot extract themselves from the nets.
The Ocean Cleanup Foundation has conducted extensive analysis and expeditions to the GPGP, removing more than one million pounds of trash as of 2024. However, the patch is believed to be rapidly accumulating, increasing "10-fold each decade" since 1945. The issue of plastic pollution in the GPGP highlights the importance of reducing single-use plastics, improving recycling infrastructure, and promoting environmental responsibility in waste management.

The patch is located between California and Hawaii
The Great Pacific Garbage Patch, also known as the Pacific Trash Vortex, is a gyre of marine debris particles in the central North Pacific Ocean. It is located between California and Hawaii, in the North Pacific Subtropical Gyre, and is the largest accumulation of ocean plastic in the world.
The patch was discovered by Charles Moore in 1997, when he was sailing from Hawaii to California and noticed a steady stream of plastic surrounding his ship. Moore alerted oceanographer Curtis Ebbesmeyer, who dubbed the region the Eastern Garbage Patch (EGP). The patch has since been the subject of numerous research expeditions and cleanup efforts.
Contrary to popular belief, the Great Pacific Garbage Patch is not a solid mass of plastic. Instead, it consists of microscopic plastic particles, with larger items such as fishing gear and shoes interspersed throughout. This makes it difficult to detect, even by satellite imagery or casual boaters in the area. However, studies indicate that the patch is rapidly accumulating, with some predicting that it will soon be visible from space.
The plastic in the patch originates from countries in Asia, North America, and South America, with China being the largest contributor. The garbage patch is a result of ocean currents concentrating plastic waste in specific areas. The impact of the patch is far-reaching, with animals migrating through or inhabiting the area consuming the plastic and ingesting toxic chemicals attached to it.

It is the largest accumulation of plastic in the ocean
The Great Pacific Garbage Patch (GPGP) is the largest accumulation of plastic in the ocean. It is located in the central North Pacific Ocean, between Hawaii and California. It was discovered in 1997 by Captain Charles Moore, who was sailing from Hawaii to California after competing in a yacht race. Moore noticed a steady stream of plastic surrounding his ship and alerted oceanographer Curtis Ebbesmeyer, who named the region the Eastern Garbage Patch (EGP).
The GPGP is a collection of marine debris, or microplastics, that has accumulated due to ocean currents. These small plastic particles are often microscopic, making the patch difficult to see from satellite imagery or even by casual boaters or divers in the area. Despite this, the patch is massive, covering an estimated 1.6 million square kilometers (620,000 square miles) and containing 45,000–129,000 metric tons of plastic. The patch is also rapidly growing, with some predicting it has increased "10-fold each decade" since 1945.
The plastic in the GPGP comes from a variety of sources, including fishing gear, shoes, and other plastic items associated with food, drinks, and household items. The Ocean Cleanup estimated that 86% of the plastics in the patch come from fishing activity, with China being the largest contributor to plastic ocean pollution. The impact of the GPGP on marine life is significant, with animals migrating through or inhabiting the area likely consuming plastic. For example, sea turtles and albatross chicks in the area have been found to have a significant portion of their diets composed of ocean plastics, which can contain toxic chemicals.
The scale of the GPGP has led to it being imagined as a solid landmass, with some reports claiming it is twice the size of Texas or three times the size of France. However, this is a misconception, as the plastic is scattered and does not form a solid mass. The patch is more accurately described as a murky or cloudy soup of plastic, with larger items intermixed. While it cannot be seen from space, the GPGP is a stark reminder of the impact of plastic pollution on our oceans and the urgent need to reduce, recycle, and promote environmental responsibility.

The patch is a result of ocean currents and marine pollution
The Great Pacific Garbage Patch is the largest accumulation of ocean plastic in the world. It is located in the central North Pacific Ocean, between Hawaii and California. The patch is formed by ocean currents, specifically the North Pacific subtropical vortex, which pushes plastic waste together in one specific area. The gyre's rotational pattern draws in waste material from across the North Pacific, incorporating coastal waters off North America and Japan.
The Great Pacific Garbage Patch is not a single, solid mass but rather a massive collection of garbage scattered across a region in the Pacific Ocean. It is made up of various types of plastic and other debris, including unidentifiable fragments, fishing and aquaculture gear, and other plastic items associated with food, drinks, and household items. The patch is a result of decades of marine pollution, with plastic debris entering the ocean in numerous ways, including runoff from land, littering, illegal dumping from boats, and the improper disposal of waste.
The patch is rapidly accumulating, with research indicating that it has increased "10-fold each decade" since 1945. It is believed to contain approximately six pounds of plastic for every pound of plankton, and the plastic in the patch has been measured since the 1970s, with calculations showing that microplastic mass concentration is increasing exponentially. The impact of this plastic pollution on marine life is significant, with animals migrating through or inhabiting this area likely consuming plastic and becoming entangled in fishing nets and other debris.
In addition to the Great Pacific Garbage Patch, there are other plastic "islands" or patches in the world's oceans. One such island is located in the Barents Sea, near the Arctic Circle, and is the smallest plastic island yet discovered. It contains 300 billion floating plastic pieces, with waste originating from Europe and the east coast of North America. This island moves along ocean currents as far north as Norway and has a variable extension, with areas of high waste density and other less compact areas.
These plastic "islands" or patches are a result of ocean currents and marine pollution, with plastic waste accumulating in specific areas due to the convergence of currents. They pose a serious threat to marine ecosystems and the health of our oceans, with plastic ingestion and entanglement causing harmful effects on marine species.

It is made up of microplastics and larger items like fishing gear
The Great Pacific Garbage Patch (GPGP) is a gyre of marine debris particles in the central North Pacific Ocean. It is not a solid island of trash, but a "plastic soup" of microplastics and larger items, like fishing gear, intermixed. Microplastics are tiny plastic particles less than five millimetres in length, and can be the result of larger plastic pieces breaking apart. They can also be microbeads, small manufactured plastic beads used in health and beauty products, which pass through water filtration systems and end up in the ocean.
Fishing gear, such as nets, lines, and ropes, is a major contributor to the GPGP. This is due to the increased fishing activity in the Pacific Ocean and the design of fishing gear, which is made to survive in the water for long periods. Fishing nets alone account for 46% of the mass in the GPGP. Derelict fishing gear poses a serious threat to marine life, as animals can get entangled in the nets and drown. It also poses a safety risk to vessels at sea, as they can get stuck in propellers.
The GPGP is estimated to be twice the size of Texas, with 180 times more plastic than biomass. It is believed to have increased "10-fold each decade" since 1945. While microplastics dominate the area by count, 92% of the mass of the patch consists of larger objects. These larger objects are continually fragmenting into smaller pieces, which are much harder to clean up.
The impact of the GPGP on the marine ecosystem is significant. Marine debris blocks sunlight from reaching plankton and algae, threatening their communities and disrupting the marine food web. Marine organisms also consume plastic, mistaking it for food, and ingest the chemicals attached to the plastic.
