The Great Pacific Garbage Patch, also known as the seventh continent and the Pacific Plastic Island, is the largest accumulation of plastic in the open ocean. It is located between Hawaii and California and covers an estimated surface area of 1.6 million square kilometres, or 620,000 square miles. This is twice the size of Texas, three times the size of France, or nearly six times the size of France according to another source. The patch is home to coastal species such as jellyfish and sponges, which are surviving and reproducing alongside open-ocean species.

The Great Pacific Garbage Patch is the largest accumulation of plastic in the open ocean
The Great Pacific Garbage Patch (GPGP) is the largest accumulation of plastic in the open ocean. It is located in the North Pacific Ocean, halfway between Hawaii and California. The GPGP is one of five oceanic accumulation areas for plastics, with the others being in the South Pacific, North Atlantic, South Atlantic, and Indian Oceans.
The GPGP is a collection of marine debris, or litter that ends up in the ocean, seas, and other large bodies of water. This debris is made up of tiny bits of plastic, called microplastics, which can't always be seen by the naked eye. Even satellite imagery doesn't show a giant patch of garbage. Instead, the microplastics of the GPGP make the water look like a cloudy soup, with larger items such as fishing gear and shoes intermixed.
The GPGP covers an estimated surface area of 1.6 million square kilometers, an area twice the size of Texas or three times the size of France. The patch is constantly changing shape and location due to seasonal and interannual variabilities of winds and currents.
The amount of debris in the GPGP continues to grow because much of it is not biodegradable. Instead of wearing down, plastics simply break into smaller and smaller pieces, known as photodegradation. These microplastics can be ingested by marine life, entering the food chain and potentially impacting human health.
Efforts are being made to clean up the GPGP, with scientists conducting extensive analyses of the area and sharing updates on plastic catches, research findings, and new projects.

It covers an estimated surface area of 1.6 million square kilometres
The Great Pacific Garbage Patch is the largest accumulation of plastic in the open ocean. It covers an estimated surface area of 1.6 million square kilometres, or 620,000 square miles. This makes it twice the size of Texas, or three times the size of France.
To put this into perspective, the patch is said to cover an area of 1,800,000 square kilometres, or 0.62 million square miles, with a concentration of 10-100 kilograms per square kilometre. That's the equivalent of 57-571 lb/sq mi. The patch is believed to contain 80,000 metric tons of plastic, or 88,000 short tons, with 1.8 trillion plastic pieces. Of this mass, 92% can be attributed to objects larger than 0.5 centimetres.
The size of the patch was determined by a team of scientists who conducted an elaborate sampling method. This involved a fleet of 30 boats, 652 surface nets, and two flights to gather aerial imagery of the debris. Due to the variability of winds and currents, the location and shape of the patch are constantly changing.
The Great Pacific Garbage Patch was discovered in 1997 by Charles J. Moore, an oceanographer. It is located between Hawaii and California and is fed by the North Pacific Gyre, a large circular current that accumulates floating particles. The plastic in the patch has been measured since the 1970s, and calculations show that microplastic mass concentration is increasing exponentially. This is due to the input of plastic being greater than the output.
The patch is not only a threat to marine life but also to human health. Microplastics ingested by marine organisms can enter the human body through the food chain. Studies have found microplastics in up to 800 species of fish, crustaceans, and molluscs, as well as in 90% of salt brands sampled worldwide.

The GPGP is located between Hawaii and California
The Great Pacific Garbage Patch (GPGP) is the largest accumulation of ocean plastic in the world, located between Hawaii and California. It is the largest of the five offshore plastic accumulation zones in the world's oceans. The GPGP covers an estimated surface area of 1.6 million square kilometres, an area twice the size of Texas or three times the size of France.
The GPGP is a vast area in the North Pacific Ocean where marine debris, primarily plastics, has accumulated due to ocean currents. Four ocean currents converge where the GPGP is located, creating an area of water known as an ocean gyre that swirls around, moving litter and waste through these currents to form at the centre of the vortex. These ocean mechanisms trap debris and litter in the area at the centre of the convergence point, which over time, contributes to the escalating growth of the patch.
The GPGP is composed of two main areas: the Western Garbage Patch, located near Japan, and the Eastern Garbage Patch, found between Hawaii and California. The Eastern Garbage Patch expands towards California and Hawaii, while the Western Garbage Patch extends from Hawaii to Japanese waters. The debris in the GPGP ranges from microscopic particles to large materials, such as abandoned fishing nets and other discarded items.
The primary cause of the GPGP is the massive amount of plastic waste that humans generate daily. It is estimated that 8-15 million tons of plastic garbage are released into the ocean from global rivers each year. Single-use plastics, such as plastic bags, straws, and plastic bottles, are significant contributors to the GPGP. These items often are not recycled and end up as ocean plastic, breaking down into microplastics over time and causing problems for marine ecosystems and ecology.

The GPGP's location and shape are constantly changing due to seasonal and interannual variabilities of winds and currents
The Great Pacific Garbage Patch (GPGP), also known as the seventh continent, is the largest accumulation of plastic in the open ocean. It is located in the North Pacific Ocean, halfway between Hawaii and California. The GPGP is a "vortex of garbage" that was discovered in 1997 by Charles J. Moore, an oceanographer.
The GPGP covers an estimated surface area of 1.6 million square kilometers, which is approximately twice the size of Texas or three times the size of France. The size and shape of the patch are determined by sampling, as most of the debris consists of small plastic particles suspended at or just below the surface, evading detection by aircraft or satellite. The mass concentration of microplastics in the patch is increasing exponentially, indicating that the input of plastic is greater than the output.
The GPGP is home to a diverse range of organisms, including coastal species such as jellyfish and sponges, which are typically found in the western Pacific coast. Some scientists are concerned about the potential impact of this mix of coastal and open-ocean species on the ecosystem. Additionally, the presence of microplastics in the food chain is a growing concern, as microscopic plastic ingested by marine organisms can eventually enter our bodies through seafood consumption.

The GPGP is home to coastal species surviving in the open ocean and reproducing
The Great Pacific Garbage Patch (GPGP) is a plastic accumulation in the Pacific Ocean, located between Hawaii and California. It is the largest accumulation of plastic in the open ocean, covering an estimated surface area of 1.6 million square kilometres. This is twice the size of Texas or three times the size of France.
The GPGP is a vortex of garbage, discovered in 1997 by Charles J. Moore, an oceanographer. The plastic in the GPGP has been measured since the 1970s, and calculations from subsequent years show that microplastic mass concentration is increasing exponentially. This is due to the input of plastic being greater than the output, and the persistence of plastic in this region. The main contributor of rubbish to the GPGP is Asia, with another significant factor being the increase in industrial fishing in the Pacific Ocean.
The presence of these coastal species in the GPGP is due to their ability to cling to plastics and be carried by currents over thousands of kilometres. This can disrupt the balance of ecosystems, as invasive organisms are introduced to new areas. The plastic in the GPGP provides a surface for the growth of bacteria, diatoms, and other microorganisms, which can be visible to the naked eye or microscopic.
