Many animals that live on or in the sea consume flotsam by mistake, as it often looks similar to their natural prey. [171] Plastic debris, when bulky or tangled, is difficult to pass, and may become permanently lodged in the digestive tracts of these animals.
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.
These methods are also referred to as mechanical grooming and nonmechanical grooming. Mechanical beach cleaning is defined as litter and/or organic material removal that relies on the work of automatic or push machinery that rakes or sieves the most superficial layer of sand. Manual cleaning involves individuals picking up trash exclusively by ...
The Interceptor is a solar-powered, automated system designed to capture and extract waste. Along with an optimized water flow path, a barrier guides rubbish towards the opening of the Interceptor and onto the conveyor belt, which delivers waste to the shuttle. The shuttle deposits the waste equally into one of six bins according to sensors.
The North Pacific Garbage Patch on a continuous ocean map. The Great Pacific Garbage Patch formed gradually as a result of ocean or marine pollution gathered by ocean currents. [37] It occupies a relatively stationary region of the North Pacific Ocean bounded by the North Pacific Gyre in the horse latitudes. The gyre's rotational pattern draws ...
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.

Livestock waste can also enter waterways and introduce excess nutrients. Nutrient pollution from animal manure is most intense from industrial animal agriculture operations, in which hundreds or thousands of animals are raised in one concentrated area. Stormwater drainage is another source of nutrient pollution.
