Realizing that previous methods of analyzing the plastic in the patch needed improvement, The Ocean Cleanup designed a new research tool, called the multi-level-trawl, which allowed measurements of 11 water layers simultaneously going as far down as 5 meters below surface level.

This trawl was then used in the Vertical Distribution Research. The multi-level-trawl allowed the team to study further down into the water and understand to which depths buoyant plastic may be distributed. Through these studies, it was observed that buoyant plastic floats primarily in the first few meters of the water. Numerous vessel owners offered the use of their ships for the mission. Of those ships, many carried behind them a Manta-trawl; including one mothership, the ft long Ocean Starr, which was able to carry two 6-meter-wide trawls and a survey balloon.

The fleet returned with over 1. Scientists present on the expedition noted that there was an alarming amount of plastic floating in the patch, and their preliminary findings indicated that there were more large objects than originally expected. 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. They took two flights and came back with over 7, single frame mosaics from the mission. Once the ocean plastic was brought back to the Netherlands, it then needed to be counted, classified and analyzed.

The first step in analyzing the plastic was to quantify it — to turn this physical matter into data. Every piece of plastic that was recovered was cleaned, counted and classified by size and type. In total, 1. Not only is the size and count of the plastic in the GPGP important to calculate, but the way in which the plastic interacts in the water helps the team learn more about the buoyancy and depths of the plastic. To test this, various experiments were performed on the plastic in environments that were intended to replicate oceanic conditions and particularly salinity.

Laboratory tests were conducted to measure the vertical speed of the plastic as it resurfaces. It is commonly known that harmful PBT Persistent Bio-accumulative Toxic chemicals are found in ocean plastics, so researchers at The Ocean Cleanup tested plastic samples from the expeditions for their chemical levels. Their results helped them to realize what chemicals are present in the patch and what that means for animals feeding there.

Plastics ranging from various type and size were analyzed by placing them in mixtures that would allow the various chemicals to be identified. A process known as Chromatography. Numerous computational and mathematical processes and methods were used throughout the study of the GPGP, allowing the team to visualize and characterize many features of the patch and the plastic within it. When the manta trawls samples were captured and then brought on the vessel, several criteria were noted in the datasheets, including the date, duration, and final coordinates of each tow.

With this information, the team was able to identify the exact location where the plastic was retrieved. The location and duration of all tows were confirmed during a post-processing phase by inspecting all the recorded datasheets against GPS trackers that were installed on all participating vessels.

There were 3 sensor technicians, 7 navigation personnel and 10 researchers who helped track the plastic from above and monitor the equipment on board.

By comparing the top view surface against dry mass of multiple objects collected during the first expedition at sea, including ghost nets, the team was able to make these estimations.

The data and imagery gathered from these objectives was eventually used by our team of computational modelers to build various models and computer-generated graphics. These served as a visual representation of the studies and tests that had been performed from the expeditions.

Science of this nature is crucial when understanding the many facets of the GPGP. These models have helped the engineers at The Ocean Cleanup to further improve the design of the cleanup system, which is set to be deployed mid What is the great pacific garbage patch?

Concentration Using data from multiple reconnaissance missions, a mass concentration model was produced to visualize the plastic distribution in the patch. Modelled mass concentration By size classes.

Vertical distribution The Ocean Cleanup measured the vertical distribution of plastic during six expeditions between to Persistency Characteristics of the debris in the Great Pacific Garbage Patch, such as plastic type and age, prove that plastic has the capacity to persist in this region.

Plastics are polymers — long-chain compounds often composed of identical molecules. Think of a string of pearls. Nearly all plastics originate from living matter formed with solar energy by photosynthesis in plants on land and sea. For example, rayon and cellophane are made from cellulose which is a polymer of glucose derived from wood and are therefore plastics. Cotton is pure cellulose and is therefore also a plastic. Natural rubber and synthetic rubber are polymers and therefore plastics.

Oil, coal, and natural gas are all products of solar energy that produced forests and sea life that turned into fossil fuels over the millennia. Today they are made into polymers such as polyethylene, polypropylene, and polyvinyl chloride, otherwise known as PVC or vinyl. To begin, despite the vast amount of propaganda, plastics are not toxic, they are inert. This is one of the reasons we package and wrap much of our food in plastic. It helps prevent spoilage from bacteria and mold, and protects the food from contamination by actual toxic substances.

If plastic were toxic, we would not wrap our food in it. Plastic does not miraculously become toxic in the ocean. There is a big difference between pollution and litter. Pollution is either a toxic substance or one that is harmful to life in other ways.

Plastic litter may appear unsightly, but like driftwood on a beach it is not toxic and does not harm life. Like driftwood in the ocean, plastic promotes life, as many marine species attach themselves to it, lay their eggs on it, or eat other species that are living on it. Floating pieces of plastic are like small floating reefs that enhance rather that harm marine life. Many plastic objects are in the form of containers, so unlike most driftwood can be used as shelter from predators and habitat for breeding.

Perhaps the most unique benefit of floating bits of plastic in the sea is their use by seabirds as an alternative for the traditional items used as digestive aids in their gizzards.

Birds have no teeth, so they swallow their food whole. All birds have two stomachs, one like ours and another that is a muscular organ, the gizzard , used to grind large hard pieces of food so they can be digested. To aid in this process, birds on the land use pebbles fed to them by their parents from birth and then they gather pebbles for themselves all their lives. There are no pebbles in the ocean, so seabirds use floating bits of pumice from undersea volcanoes, bits of hard wood, floating nuts from trees, and since plastic was introduced to the oceans about 60 years ago, suitable bits of floating plastic.

Many studies by bird specialists have found that this has no negative effects on chicks or adults. They know what a bird gizzard is, but they never use that word. They know they are lying for the sake of notoriety and donations. It would be beneficial to sea life if the environmental community and the international fishing industry would work to develop a program to prevent damaged fishnets from being thrown in the ocean.

It should be possible to incentivize fishers to bring their damaged nets to the dock where they can be recycled or disposed of in a manner that does no harm. See more here: bizpacreview.

If it really exists then why all the discussion of it and no attempt to collect it. Prince William could have an Earthshot project if he really cared. On the other end, the radical environmentalist liars extrapolate that, if there is a Pacific Ocean gyre of plastic, there must be one in each of the other oceans. The propaganda is so much that some have proposed putting laid off fishing vessels to work harvesting this mountain of plastic.
