The Great Pacific Garbage Patch, often referred to as 'Trash Island', is a collection of marine debris located in the central North Pacific Ocean, halfway between California and Hawaii. It is the largest accumulation of plastic in the open ocean, with an estimated 1.8 trillion pieces of plastic, 94% of which are microplastics. The patch was discovered in 1997 by Charles Moore, who continues to raise awareness about plastic pollution through his environmental organization, the Algalita Marine Research Foundation. While often imagined as a solid mass of plastic or an island, the patch is actually a widely dispersed area of tiny plastic particles that are not easily visible to the naked eye or through satellite imagery.

What You'll Learn
The Great Pacific Garbage Patch is not a floating island
The Great Pacific Garbage Patch (GPGP) is a gyre of marine debris particles in the central North Pacific Ocean. It is located from roughly 135°W to 155°W and 35°N to 42°N, halfway between California and Hawaii. The GPGP is the largest accumulation of plastic in the open ocean, covering an estimated surface of 1.6 million square kilometres.
Despite common public perception, the GPGP is not a floating island of garbage. Its low density of 4 particles per cubic metre prevents detection by satellite imagery or even by casual boaters or divers in the area. The patch is a widely dispersed area consisting primarily of "fingernail-sized or smaller"—often microscopic—particles in the upper water column known as microplastics. These microplastics can't always be seen by the naked eye and make the water look like a cloudy soup, intermixed with larger items such as fishing gear and shoes.
The GPGP is made up of the Western Garbage Patch, located near Japan, and the Eastern Garbage Patch, located between Hawaii and California. These areas of spinning debris are linked by the North Pacific Subtropical Convergence Zone, located a few hundred kilometres north of Hawaii. The patch's location and shape are constantly changing due to seasonal and interannual variabilities of winds and currents.
The amount of debris in the GPGP accumulates because much of it is not biodegradable. Plastics, for example, do not wear down; they simply break into smaller pieces. The patch is rapidly accumulating, with research indicating that it has 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.
The Ocean Cleanup has been working to remove trash from the GPGP, reaching a milestone of 20 million kg of trash removed by November 2024. However, it is important to note that the GPGP is not a floating island but rather a vast area of dispersed microplastics and larger debris.

It is a gyre of marine debris in the central North Pacific Ocean
The Great Pacific Garbage Patch is a gyre of marine debris in the central North Pacific Ocean. It is located between Hawaii and California, halfway between the two states. The gyre is a collection of plastic and floating trash originating from the Pacific Rim, including countries in Asia, North America, and South America.
The patch is often referred to as "Trash Island", leading to misconceptions about its appearance. It is not a solid mass of plastic but rather a widely dispersed area consisting primarily of microscopic particles in the upper water column, known as microplastics. These microplastics are often too small to be seen by the naked eye and do not form a continuous patch of easily visible marine debris. Instead, the ocean in this area may look like a cloudy or murky soup, with larger items such as fishing gear and shoes interspersed.
The Great Pacific Garbage Patch is the largest accumulation of plastic in the open ocean and is estimated to cover 1.6 million square kilometres, twice the size of Texas or three times the size of France. It is challenging to measure the exact size and extent of the patch due to the dispersed nature of the microplastics and the fact that denser debris can sink several meters beneath the surface.
The amount of debris in the patch accumulates because much of it is not biodegradable. Plastics break down into smaller and smaller pieces, known as microplastics, which can be harmful to marine life. Research indicates that the patch is rapidly accumulating, with a prediction of a tenfold increase each decade since 1945.
Efforts to clean up the Great Pacific Garbage Patch are ongoing, with organisations such as The Ocean Cleanup working to remove trash from the area. By the end of 2024, The Ocean Cleanup had removed more than one million pounds of trash from the patch, equivalent to 0.5% of the total accumulated trash.

The patch is made up of microplastics and larger items
The Great Pacific Garbage Patch, also known as the Pacific trash vortex or North Pacific Garbage Patch, is a collection of marine debris in the central North Pacific Ocean. It is located between Hawaii and California, halfway between the two states. The patch is often incorrectly referred to as 'Trash Island'. This nickname was likely coined because it is easier to visualise, and it makes the problem more tangible. However, this image is far from accurate.
The patch is not a solid mass of plastic, but a widely dispersed area consisting primarily of "fingernail-sized or smaller"—often microscopic—particles in the upper water column known as microplastics. These microplastics are often intermixed with larger items, such as fishing gear, shoes, and other litter. Microplastics account for 94% of the estimated 1.8 trillion pieces of plastic that make up the patch, while 92% of the mass of the patch consists of larger objects. These larger objects include plastic lighters, toothbrushes, water bottles, pens, baby bottles, cell phones, plastic bags, and nurdles.
The patch covers 1.6 million square kilometres (0.62 million square miles) with a concentration of 10–100 kilograms per square kilometre (57–571 lb/sq mi). It is believed to be rapidly accumulating, increasing "10-fold each decade" since 1945. This accumulation occurs because much of the debris is not biodegradable. Plastics, for instance, do not wear down; they simply break into tinier and tinier pieces.
The Great Pacific Garbage Patch is the largest accumulation of plastic in the open ocean, with 180 times more plastic than marine life. It is so big that it has been nicknamed the 'eighth continent'.

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, halfway between California and Hawaii. It is often referred to as the "Pacific trash vortex" or “Trash Island". This nickname is misleading, as the GPGP is not a solid mass of plastic but rather a widely dispersed area consisting primarily of microscopic particles in the upper water column, known as microplastics. These microplastics are often the result of larger pieces of plastic breaking down into smaller fragments over time.
The GPGP covers approximately 1.6 million square kilometres, or 620,000 square miles, and contains an estimated 80,000 to 129,000 metric tons of trash. The mass of the patch is dominated by larger objects, with 92% of it made up of items larger than 0.5 centimetres. Common items found in the patch include plastic lighters, toothbrushes, water bottles, pens, baby bottles, cell phones, plastic bags, and nurdles. The patch also contains a large amount of discarded fishing gear, such as nets, lines, and buoys, which account for a significant portion of the plastic marine debris in the area.
The GPGP was discovered in 1997 by Captain Charles Moore, who was sailing from Hawaii to California after competing in a yacht race. Moore and his crew noticed millions of pieces of plastic surrounding their ship and were shocked by the extent of the pollution. The patch has since become a symbol of the environmental crisis our planet is facing and has mobilised the scientific community to take action.
Despite the efforts of organisations like The Ocean Cleanup, which has removed millions of kilograms of trash from the GPGP, the patch continues to grow. Research indicates that the patch is rapidly accumulating, with predictions that it has increased "10-fold each decade" since 1945. This growth is due to the constant influx of plastic pollution from various sources, including improper waste disposal on land and waste from ships. The GPGP is now more than three times the size of France, and its impact on marine life is devastating, with animals migrating through or inhabiting the area likely consuming plastic and other debris.

The patch is growing and negatively impacting marine life
The Great Pacific Garbage Patch (GPGP) is a collection of marine debris in the central North Pacific Ocean. It is located between California and Hawaii and is the largest accumulation of plastic in the open ocean. The GPGP is often referred to as "Trash Island", which creates a misleading image of a large and continuous patch of easily visible marine debris. In reality, the patch is a widely dispersed area consisting primarily of suspended "fingernail-sized or smaller"—often microscopic—particles in the upper water column known as microplastics. These microplastics cannot always be seen by the naked eye and do not show up on satellite imagery, making it difficult to detect the patch.
The patch is growing due to the constant addition of plastic waste from various sources. Plastic waste in the GPGP comes from countries in Asia, North America, and South America. Improper waste disposal, illegal dumping, and littering are significant contributors to the plastic pollution in the GPGP. Marine debris is also generated from fishing vessels, stationary platforms, cargo ships, marinas, ports, rivers, harbors, docks, and storm drains. The durability and low cost of plastic contribute to its widespread use, but the lack of biodegradability means that plastic waste accumulates and breaks down into smaller pieces over time.
The growth of the GPGP has severe negative impacts on marine life. The high concentration of plastic in the GPGP means that animals migrating through or inhabiting this area are likely to consume plastic or get entangled in it. Sea turtles, for example, often mistake plastic bags for jellyfish, their favorite food, and can choke or sustain internal injuries. Plastic debris can also lead to entanglement and injury in other marine animals, such as the endangered Steller sea lion. The chemicals present in plastics can enter the food chain when consumed by marine life, leading to bioaccumulation and potential health risks for humans as well, as these chemicals can move up the food chain.
Efforts to clean up the GPGP are challenging due to the dispersed nature of the microplastics and the financial burdens associated with cleanup operations. Additionally, the small size of the microplastics makes it difficult to scoop up the trash without also capturing small sea animals. However, organizations like The Ocean Cleanup are actively working to remove plastic waste from the GPGP and have removed significant amounts of trash. While the GPGP is a pressing issue, it is important to note that it is not a continuous island of trash, and public perception of the patch should not detract from the very real environmental concerns it poses.
