Critical to success are Debris Free Ocean’s 12,000 volunteers. Katy Roth has been involved for nine years as a volunteer, helping out with beach and reef cleanups, eco fashion shows and clothing ...
Moore is the founder of the Algalita Marine Research and Education [4] in Long Beach, California.. In 2008 the Foundation co-sponsored the JUNK Raft project, to "creatively raise awareness about plastic debris and pollution in the ocean", and specifically the Great Pacific Garbage Patch trapped in the North Pacific Gyre, by sailing 2,600 miles across the Pacific Ocean on a 30-foot-long (9.1 m ...
Plastic pollution in the ocean is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean.
By using data on surface plastic concentration (pieces of plastic per km 2) from 1972 to 1985 (n=60) and 2002–2012 (n=457) within the same plastic accumulation zone, the study found the mean plastic concentration increase between the two sets of data, including a 10-fold increase of 18,160 to 189,800 pieces of plastic per km 2.
Plastic degradation in marine bacteria describes when certain pelagic bacteria break down polymers and use them as a primary source of carbon for energy. Polymers such as polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET) are incredibly useful for their durability and relatively low cost of production, however it is their persistence and difficulty to be properly ...
Debris on beach near Dar es Salaam, Tanzania Debris collected from beaches on Tern Island in the French Frigate Shoals over one month. Researchers classify debris as either land- or ocean-based; in 1991, the United Nations Joint Group of Experts on the Scientific Aspects of Marine Pollution estimated that up to 80% of the pollution was land-based, [5] with the remaining 20% originating from ...
This is an accepted version of this page This is the latest accepted revision, reviewed on 11 December 2024. Large floating field of debris in the North Atlantic Ocean The North Atlantic Gyre is one of five major ocean gyres. The North Atlantic garbage patch is a garbage patch of man-made marine debris found floating within the North Atlantic Gyre, originally documented in 1972. A 22-year ...
The South Pacific garbage patch is an area of ocean with increased levels of marine debris and plastic particle pollution, within the ocean's pelagic zone. This area is in the South Pacific Gyre , which itself spans from waters east of Australia to the South American continent, as far north as the Equator , and south until reaching the ...
