Plastics in Our Oceans As our consumption of plastic mounts, so too does the danger to marine life. Before the days of plastic, when fishermen dumped their trash overboard or lost a net, it consisted of natural materials--metal, cloth or paper that would either sink to the bottom or biodegrade quickly.

Marine Debris Learn how plastic in the ocean affects sea turtles and other wild animals. Hundreds of thousands of sea turtles, whales, and other marine mammals, and more than 1 million seabirds die each year from ocean pollution and ingestion or entanglement in marine debris. Marine debris is manmade waste that is directly or indirectly disposed of in oceans, rivers, and other waterways.

Great Pacific garbage patch Visualisation showing ocean garbage patches. The Great Pacific garbage patch, also described as the Pacific trash vortex, is a gyre of marine debris particles in the central North Pacific Ocean located roughly between 135°W to 155°W and 35°N and 42°N.

Landfill on the High Seas: Why's the Ocean Full of Trash? “They are there,” he said. “There are hundreds of thousands of objects there and that is the garbage patch.”. The North Pacific gyre is the size of around 9 million soccer field, and contains 30 percent of the world’s ocean garbage. “If you leave LA and you sail towards Hawaii, after maybe 400, 500 miles you begin to see little tiny fragments of plastic trash,” Eriksen said.

What is marine debris? Marine debris is more than an eyesore. With marine debris, pictures speak louder than words. Marine debris injures and kills marine life, interferes with navigation safety, and poses a threat to human health. Our oceans and waterways are polluted with a wide variety of marine debris ranging from soda cans and plastic bags to derelict fishing gear and abandoned vessels.

Ocean Trash Plaguing Our Sea Endangered species, Human impacts, Pacific islands. Garbage patches in the ocean aren't piled-up islands of trash and debris, as is the common perception. But that doesn't mean the tiny, swirling plastic bits are nothing to worry about.The currents of the North Pacific gyre collect trash—mostly bits of microscopic plastic—into what are known as garbage patches..n the Pacific Ocean, four ocean currents merge to form the North Pacific gyre, also known as the North Pacific Subtropical High, which spans the western US to Japan, and Hawaii to California.

What is a Debris Flow? A debris flow is a moving mass of loose mud, sand, soil, rock, water and air that travels down a slope under the influence of gravity. To be considered a debris flow the moving material must be loose and capable of flow, and, at least 50% of the material must be sand-size particles or larger. mud flow is composed of mud and water. Debris flows have larger particles-at least 50% of a debris flow is made-up of sand-size or larger particles. Debris flows can be triggered by many different situations.

10 Most Common Types Of Ocean Trash And trash wasn’t all they found. Volunteers encountered reptiles, birds, invertebrates, mammals, fish, and coral species that were killed by plastic bags, fishing line, plastic bottles, and other trash in the ocean. Although the tsunami is responsible for the spread of some of this debris, most of it is preventable.

What you can do to reduce marine pollution Picking up other people’s rubbish, if it is safe, is an easy way to help reduce pollution on our beaches and in the ocean. Some people pick up beach rubbish in groups – this is called a beach clean-up. Beach clean-ups are doing great things to reduce marine pollution.

- Eighty percent of plastic pollution that enters the ocean originates from land. Common sources include: recreational beach users, people who drop litter on sidewalks and streets, plastics manufacturers and transporters, illegal dumping, and areas with inadequate trash receptacles.All land-based plastic pollution has the potential to become ocean pollution. Refusing to use disposable plastic items such as plastic bags, water bottles and utensils, is the responsibility of every one of us. 2  Some of the most common plastics found during SOS beach and river cleanups are cigarette butts, plastic pieces, plastic bags and styrofoam pieces.

The Trash Vortex In the North Pacific is an area the size of Turkey of floating plastic rubbish. Take a walk along almost any beach anywhere in the world and washed ashore will almost certainly be either plastic bags and bottles, or containers. Perhaps plastic drums or expanded polystyrene packing.

Marine layer Afternoon smog within a coastal marine layer in West Los Angeles. A marine layer is an air mass which develops over the surface of a large body of water such as the ocean or large lake in the presence of a temperature inversion. The inversion itself is usually initiated by the cooling effect of the water on the surface layer of an otherwise warm air mass.

The Problem of Marine Plastic Pollution The Problem of Marine Plastic Pollution. Most marine debris (80%) comes from trash and debris in urban runoff, i.e. land-based sources. Key components of land-based sources include litter, trash and debris from construction, ports and marinas, commercial and industrial facilities, and trash blown out of garbage containers, trucks, and landfills.
