See full version: Which Ocean is the Cleanest
The North Atlantic Ocean holds about 930 billion pieces of plastic. The North Atlantic Gyre led to the formation of the North Atlantic garbage patch which accounts for a large number of the plastics. The ocean lies between the East Coast of the United States, Western Europe, Northeast South America, and West Africa. These regions are known to contribute significantly to the pollution of the ocean.
The South Pacific is the least polluted of the world's oceans.
There are about 150 million metric tons of plastic in the oceans and a further 8 million metric tons are added to the oceans annually. Plastic is an important material to humans but its inability to decompose makes more destructive than initially anticipated. Once plastic has been manufactured, it cannot be destroyed but it can be recycled, transformed into another plastic product, or dumped into landfills and oceans. Even when they are dumped in landfills, plastics are swept into rivers and streams, and find their way into the oceans. Plastic does more harm to the ocean than on land because marine animals do not have the ability to differentiate between plastic and prey. There are about five trillion plastic pieces floating in the earth's oceans.
The Indian Ocean was thought to be the only ocean without a garbage patch until the India Ocean Patch was discovered in 2010. The Ganges and the Indus rivers account for a large percentage of the pollutants in the Indian Ocean. The two rivers are among of the ten rivers that account for 90% of the pollution in the oceans.
The South Pacific and South Atlantic Oceans are the least polluted with 297 billion and 491 billion plastic pieces respectively. Both oceans have gyres but limited human activities makes them cleaner than the rest. Both oceans are also located in the Southern Hemisphere which is less inhabited than the Northern Hemisphere. The oceans are less traversed by ships and have less inhabited islands compared to the oceans in the Northern Hemisphere.

The South Pacific is the least polluted of the world's oceans.
The most polluted ocean is the North Pacific. It holds about two trillion pieces representing a third of the total plastics in the ocean. It is also home to the Great Pacific Garbage Patch which is the largest floating garbage patch in the world. The North Pacific is located between Asia and the West Coast of the US. It is a major shipping route between Asia and North America, and a lot of waste is dumped by ocean vessels.
The South Pacific and South Atlantic Oceans are the least polluted with 297 billion and 491 billion plastic pieces respectively. Both oceans have gyres but limited human activities makes them cleaner than the rest. Both oceans are also located in the Southern Hemisphere which is less inhabited than the Northern Hemisphere.

Why move through the oceans if the oceans can move through you? By fixing the “ships” to the seabed and letting the rotating currents do their work — vast amounts of funds, manpower and emissions will be saved. The platforms will, of course, be completely self-supportive receiving their energy from sun, currents and waves. And inspired by my diving at the Azores, it now actually seems that the best shape for these platforms is that of a Manta Ray, by letting its wings sway like a real manta, we can assure contact of the inlet with the surface even in the roughest weather.
But about a year ago, when I was on my way to the hairdresser’s and I must admit I don’t go there often but I had this little epiphany. I saw even old people throwing rubbish in the water and I thought, well some people will just never learn, will they? We’ll need the combination of both roads and we’ll need them soon.
Why don’t we just clean it up? There are a multiple reasons why current plastic pollution researchers believe we should focus on prevention, for example through education, rather than attempting a cleanup operation. Because we would need to deal with 5 colossal areas — each moving around. Plastic sizes ranging from these massive ghost nets to molecules — bycatches and emissions.
I then went on a holiday to Greece taking this manta trawl with me, which is the common device for sampling plastic, and so I had to leave home all my clothes due to low cost airlines weight limit policies. more
Because there is no mesh size, we can even get out the smallest particles, and since all organisms can simply move under the booms, we’ll be able to eliminate bycatches by 99.98%. [links]
If we want to eat a biscuit nowadays, we have to buy a biscuit within a plastic wrapper, within a plastic tray, within a cardboard box, within a plastic foil, within a plastic bag. It’s not hazardous nuclear waste — it’s a biscuit.
Research shows the majority of plastic by mass is currently in the larger debris. By removing the plastic while most of it is still large, we prevent it from breaking down into dangerous microplastics. [links]
The Ocean Cleanup is developing a passive system, using the ocean currents as its driving force to catch and concentrate the plastic. By suspending a large sea anchor in a deep, slow moving water layer, we can slow down the system enough so that the plastic moves faster than the cleanup system. This will cause the plastic to accumulate against the cleanup system. [links]
Due to the screen’s U-shape, the plastic is funneled towards the center of the system. The highly concentrated debris is buffered until it is extracted and shipped to land. For more specifics about our system, please visit the technology page. [links]
Waves, winds and currents make the plastic move in a certain manner. The same forces will act on our roaming systems, causing them to gravitate to the areas in the garbage patch with the highest concentration of plastic. here
Our models indicate that a full-scale system roll-out could clean up 50% of the Great Pacific Garbage Patch in 5 years. here
Trash accumulates in 5 ocean garbage patches, the largest one being the Great Pacific Garbage Patch, located between Hawaii and California. If left to circulate, the plastic will impact our ecosystems, health and economies. Solving it requires a combination of closing the source, and cleaning up what has already accumulated in the ocean.
