The Great Pacific Garbage Patch, also known as the Pacific trash vortex, is a collection of marine debris in the North Pacific Ocean. It is located between Hawaii and California and is formed by four currents: the California current, the North Equatorial current, the Kuroshio current, and the North Pacific current. The patch is not a single giant floating island but a massive collection of garbage, including microplastics, scattered across a region in the Pacific Ocean. The size of the patch is estimated to be 1.6 million square kilometres, with a concentration of 10-100 kilograms per square kilometre. The Great Pacific Garbage Patch is a growing environmental concern, with plastic pieces in the patch increasing 10-fold each decade since 1945.

What You'll Learn
The Great Pacific Garbage Patch is not a solid mass
The Great Pacific Garbage Patch is a collection of marine debris in the North Pacific Ocean. It spans waters from the West Coast of North America to Japan and is the largest accumulation of plastic in the open ocean. The patch is actually made up of two parts: the Western Garbage Patch, located near Japan, and the Eastern Garbage Patch, located between the US states of Hawaii and California.
The name "Great Pacific Garbage Patch" 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 photography. However, this is not the case. While the patch is densely distributed, it is scattered and does not form a solid mass.
The Ocean Cleanup, a foundation dedicated to removing plastic from the patch, has conducted the most extensive analysis of the area. During six expeditions between 2013 and 2015, they measured the vertical distribution of plastic. Their results showed that buoyant plastic mass is distributed within the top few meters of the ocean. Larger pieces were observed to resurface much more rapidly than smaller pieces.
The patch is almost entirely made up of tiny bits of plastic, called microplastics, which cannot always be seen by the naked eye. Even satellite imagery doesn’t show a giant patch of garbage. The microplastics of the Great Pacific Garbage Patch can simply make the water look like a cloudy soup. This soup is intermixed with larger items, such as fishing gear and shoes.
The Great Pacific Garbage Patch is a serious environmental concern. As of 2024, The Ocean Cleanup had removed more than one million pounds of trash from the patch, or 0.5% of the total accumulated trash.

The patch is made up of microplastics
The Great Pacific Garbage Patch is a collection of marine debris in the North Pacific Ocean. It is located between Hawaii and California and spans waters from the West Coast of North America to Japan. The patch is made up of microplastics, which are tiny pieces of plastic that are often microscopic and cannot be seen by the naked eye. These microplastics come from larger pieces of plastic that break down over time due to exposure to UV light from the sun and crushing waves. They can also come from waste thrown away on land, abandoned fishing gear, and waste from ships.
The Great Pacific Garbage Patch is not a solid mass or a single giant floating island, but rather tons of floating debris that is pushed together in one specific area by the currents of the Pacific Ocean. The North Pacific Subtropical Gyre, formed by four currents (the California current, the North Equatorial current, the Kuroshio current, and the North Pacific current), draws debris into its stable center, where it becomes trapped. This gyre contains approximately six pounds of plastic for every pound of plankton.
The patch covers 1.6 million square kilometers and contains 80,000 metric tons of plastic, with 1.8 trillion plastic pieces. It is the largest accumulation of ocean plastic in the world and is constantly growing. The plastic in the patch has been measured since the 1970s, and calculations show that the microplastic mass concentration is increasing exponentially. This is due to the constant flow of plastic debris into the patch from various sources, including runoff from land, littering, illegal dumping of fishing gear from boats, and waste from ships.
The impact of the Great Pacific Garbage Patch on marine life is significant. Animals migrating through or inhabiting this area are likely consuming plastic, which can contain toxic chemicals. For example, sea turtles and albatross chicks have been found to have a significant percentage of their diets or wet mass composed of plastics from the patch. The patch also poses a threat of entanglement for marine species, with old fishing nets and gear accounting for a large portion of the mass in the patch.
While the exact size of the patch is challenging to determine due to its constant change with ocean currents and wind, it is estimated to be twice the size of Texas and three times the size of France. The patch is difficult to detect by satellite imagery or even by casual boaters or divers in the area due to its low density and widely dispersed nature. Despite this, the Great Pacific Garbage Patch is a significant environmental concern, and efforts are being made to clean up and address the issue.

It's the largest accumulation of ocean plastic in the world
The Great Pacific Garbage Patch, also known as the Pacific trash vortex, is the largest accumulation of ocean plastic in the world. It is located in the central North Pacific Ocean, spanning waters from the West Coast of North America to Japan. The patch is made up of the Western Garbage Patch, located near Japan, and the Eastern Garbage Patch, located between Hawaii and California.
The Great Pacific Garbage Patch is not a single, solid mass but a collection of marine debris, including microplastics and larger items such as fishing gear. The patch covers approximately 1.6 million square kilometres (0.62 million square miles), with a concentration of 10-100 kilograms per square kilometre. It is estimated to contain 1.8 trillion pieces of plastic, with a total weight of 80,000 metric tons.
The accumulation of plastic in the Great Pacific Garbage Patch is a result of ocean currents, particularly the North Pacific Subtropical Gyre, which is formed by four currents: the California Current, the North Equatorial Current, the Kuroshio Current, and the North Pacific Current. These currents create a circular motion that draws debris into the centre, trapping it. The plastic in the patch comes from a variety of sources, including runoff from land, littering, improper waste disposal, construction, and illegal dumping from boats, such as fishing gear.
The impact of the Great Pacific Garbage Patch on marine life is significant. Animals migrating through or inhabiting this area are likely to consume plastic, which can contain toxic chemicals. For example, sea turtles and albatross chicks have been found with high percentages of plastic in their diets. The plastic and other debris can also entangle marine animals, causing injuries and death.
Efforts to clean up the Great Pacific Garbage Patch are ongoing. By the end of 2024, the Ocean Cleanup had removed more than one million pounds of trash from the area, but the patch continues to grow, with research indicating a tenfold increase each decade since 1945.

The patch is constantly growing
The Great Pacific Garbage Patch, also known as the Pacific trash vortex, spans waters from the West Coast of North America to Japan. It is located in the central North Pacific Ocean, between Hawaii and California. The patch is not a single giant floating island, but rather tons and tons of floating plastic debris pushed together in one specific area by the currents of the Pacific Ocean.
The entire patch is bounded by the North Pacific Subtropical Gyre, formed by four currents—the California Current, the North Equatorial Current, the Kuroshio Current, and the North Pacific Current—rotating clockwise around an area of 20 million square kilometers. The area in the center of a gyre tends to be very calm and stable, and the circular motion of the gyre draws debris into this stable center, where it becomes trapped.
The Great Pacific Garbage Patch is constantly growing due to the continuous addition of plastic waste and debris. While microplastics dominate the area by count, 92% of the mass of the patch consists of larger objects. Some of the plastic is over 50 years old, and includes items such as plastic lighters, toothbrushes, water bottles, pens, baby bottles, cell phones, plastic bags, and nurdles. Research indicates that the patch is rapidly accumulating, with estimates suggesting it has increased "10-fold each decade" since 1945.
The size of the patch is challenging to determine due to its constant expansion and the dynamic nature of ocean features. The borders and content of the area are subject to change due to ocean currents and wind. However, it is estimated to cover 1.6 million square kilometers, with a concentration of 10-100 kilograms per square kilometer. The patch is believed to contain 80,000 metric tons of plastic, and efforts by the Ocean Cleanup project have removed over one million pounds of trash from the patch as of 2024.
The Great Pacific Garbage Patch poses a significant threat to marine life in the region. Animals migrating through or inhabiting this area are likely to consume plastic, with sea turtles and Laysan albatross chicks from Kure Atoll and Oahu Island found to have significant percentages of plastic in their diets. Additionally, fishing nets account for a large portion of the mass in the patch, endangering animals that become entangled in them.
