Marine debris, also known as marine litter, is human-created solid material that has deliberately or accidentally been released in seas or the ocean. Floating oceanic debris tends to accumulate at the center of gyres and on coastlines , frequently washing aground, when it is known as beach litter or tidewrack.
A consignment of Friendly Floatee toys, manufactured in China for The First Years Inc., departed from Hong Kong on a container ship, the Evergreen Ever Laurel, [1] destined for Tacoma, Washington.
Marine plastic pollution 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. Eighty percent of marine debris is plastic.
The positioning of Hawaii in particular makes it a high-impact target for marine debris, given the natural ocean currents and its relative location to the North Pacific Subtropical Convergence Zone. [1] As a result, marine debris is not limited to waste from the islands exclusively but is also carried from other locations around the world.
While marine pollution can be obvious, as with the marine debris shown above, it is often the pollutants that cannot be seen that cause most harm.. Marine pollution occurs when substances used or spread by humans, such as industrial, agricultural and residential waste, particles, noise, excess carbon dioxide or invasive organisms enter the ocean and cause harmful effects there.
Plastics accounts for 80% of waste dispersed in the marine and coastal environment of the Mediterranean Sea. [24] Recent studies focus on the types of plastics found and primarily on the issue of microplastics, both at a global but also at a regional level, as in the case of the Mediterranean Sea, which was identified as a "target hotspot of the world" due to its amounts of microplastics ...
Beach wrack or marine wrack is organic material (e.g. kelp, seagrass, driftwood) and other debris deposited at high tide on beaches and other coastal areas. This material acts as a natural input of marine resources into a terrestrial system, providing food and habitat for a variety of coastal organisms.
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 ...
