Is the Great Pacific Garbage Patch mostly plastic?
For many people, the idea of a “garbage patch” conjures up images of an island of trash floating on the ocean. In reality, these patches are almost entirely made up of tiny bits of plastic, called microplastics.

Is the great garbage patch getting smaller?
The Garbage Patch is shrinking because of bacteria, but do we have to stop them? Since the discovery of the Great Pacific Garbage Patch in 1997, the already massive quantities of plastics and micro-plastics have grown even further in the area, strangling the local ecosystem.
Can you see the garbage patch on Google Earth?
Most of the plastic is particulate and/or a bit under the surface so you can't see it in the imagery. A number of groups are starting to focus on collecting more data about the gyre via expeditions and sampling – we'd love to see one or more of them produce maps that could be viewed in Google Earth.
What percentage of plastic actually sinks to the ocean floor?
About 18.2 million tons sink to the ocean floor. Every year, an astonishing 260 million tons of plastic waste is produced, and about 10% of it ends up in the ocean. Over time, roughly 70% of the plastic that ends up in the ocean sinks to the ocean floor.
Who dumps plastic in the ocean?
The top three countries are India, China, and Indonesia. All 15 countries dump the equivalent weight of 2,403 whales' worth of plastic into the ocean. India is responsible for 126.5 million kg of plastic. “Over 70.7 million kg of the plastic that ends up in the ocean comes from China.

How does the largest percentage of plastic in the marine garbage patches enter the water?
Most of the plastic in our oceans comes from land-based sources: by weight, 70% to 80% is plastic that is transported from land to the sea via rivers or coastlines. The other 20% to 30% comes from marine sources such as fishing nets, lines, ropes, and abandoned vessels.
What is the Great Pacific Garbage Patch quizlet?

What was the Ocean Cleanup mission?
Over the course of three years, researchers at The Ocean Cleanup went on several data collection missions. This included the Multi-Level-Trawl expedition, where they analyzed the depth at which buoyant plastic debris may be vertically distributed; the Mega Expedition using vessels to cross the patch with many trawls at once; and the Aerial Expedition which involved the use of a plane flying at low altitude to observe the debris from above.
How do plastics show resiliency?
The stronger, more buoyant plastics show resiliency in the marine environment, allowing them to be transported over extended distances. They persist at the sea surface as they make their way offshore, transported by converging currents and finally accumulating in the patch.
Why did the Mega Expedition team want to learn more about the Megaplastics?
After the Mega Expedition, the team wanted to learn more about these large plastic pieces that were difficult to come by. Megaplastics are more scattered than the smaller plastics , and, to study this important aspect of the patch, the team needed to cover an even larger area.
Why is the GPGP shape changing?
Due to seasonal and interannual variabilities of winds and currents, the GPGP’s location and shape are constantly changing. Only floating objects that are predominantly influenced by currents and less by winds were likely to remain within the patch.

Where does the plastic in the garbage come from?
Some 80 percent of the plastics in the garbage patch come from the land. It takes years for debris to travel from the coasts to the gyre, and, as it is carried along, photodegradation causes the plastics to break down into tiny, nearly invisible bits.

Is the garbage patch in the ocean toxic?
In 2015 and 2016 the Dutch-based organization Ocean Cleanup found that the density of the debris in the garbage patch was much greater than expected and that the plastics absorbed pollutants, making them poisonous to marine life.

How many pieces of plastic are in the patch?
More than 1.8 trillion pieces of plastic are in the patch, that weigh an estimated 80,000 tonnes. These figures are much higher than previous calculations.
What is the patch of plastic?
This is because the patch is a widely dispersed area consisting primarily of suspended "fingernail-sized or smaller bits of plastic", often microscopic, particles in the upper water column known as microplastics. Researchers from The Ocean Cleanup project claimed that the patch covers 1.6 million square kilometers. 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 ." The small fibers of wood pulp found throughout the patch are "believed to originate from the thousands of tons of toilet paper flushed into the oceans daily."

How big is a patch?
Instead, the size of the patch is determined by sampling. Estimates of size range from 700,000 square kilometres (270,000 sq mi) (about the size of Texas) to more than 15,000,000 square kilometres (5,800,000 sq mi) (about the size of Russia).

How is the size of a pelagic patch determined?
Instead, the size of the patch is determined by sampling. Estimates of size range from 700,000 square kilometres (270,000 sq mi) (about the size of Texas) to more than 15,000,000 square kilometres (5,800,000 sq mi) (about the size of Russia). Such estimates, however, are conjectural given the complexities of sampling and the need to assess findings against other areas. Further, although the size of the patch is determined by a higher-than-normal degree of concentration of pelagic debris, there is no standard for determining the boundary between "normal" and "elevated" levels of pollutants to provide a firm estimate of the affected area.
