Antarctic Circumpolar Current ACC Noun most powerful surface ocean current in the world, which rotates clockwise around the continent of Antarctica.
What can we do? It is estimated that more than 100,000 marine animals die each year linked to trash related causes.

Also called an autotroph.
Tropical gyre s form near the Equator. The following are just a few of the strange items that have washed up on shores: Debris in the garbage patches is primarily made up of plastic pieces less than five millimeters in size, called microplastics.
Not only have we overpopulated, but we have created a global society of waste generators, unnecessary tonnage of fossil-fuel created plastic is demanded in almost every product in our daily life, then we cast them aside instead of reusing and recycling.
Near the coast of Japan, the bottle may travel north on the powerful Kuroshiro Current.
In addition, gyres result in the slow movement of water allowing the trash to collect. As you pointed out, debris items can have different densities and buoyancies, and with moving currents, winds, and waves, these debris items are constantly being moved and mixed, thus being found throughout the water column.
The specific gravity of seawater varies between 1. These dangers are compound ed by the fact that plastics both leach out and absorb harmful pollutant s.
Plastic refers to bottled water containers, caps on sodas drinks, plastic bags, bin-bags, take out containers, etc. The North Atlantic Current and winter monsoon current are cool currents. People in Washington and Oregon snatched up the shoes on shore, holding swap meets to find matched pairs to wear or sell.
They have correlate d this expansion with increases in sea-surface temperatures—warm waters generally have far fewer nutrients than cold water. Horse Latitudes Many ocean gyres are found in what are called the horse latitudes, between 30 and 35 degrees north and south.
In the ocean, the sun breaks down these plastics into tinier and tinier pieces, a process known as photodegradation. Cleaning up marine debris is not as easy as it sounds. Many thanks! Thanks for your comment.
