In the 1950s, the importance of government intervention with marine pollution protocol was recognized at the First Conference on the Law of the Sea. [77] Ocean dumping is controlled by international law, including:

Flotsam can be blown by the wind, or follow the flow of ocean currents, often ending up in the middle of oceanic gyres where currents are weakest. Within garbage patches, the waste is not compact, and although most of it is near the surface of the ocean, it can be found up to more than 30 metres (100 ft) deep in the water. [1]
Within garbage patches, the waste is not compact, and although most of it is near the surface of the ocean, it can be found up to more than 30 metres (100 ft) deep in the water. [127] Patches contain plastics and debris in a range of sizes from microplastics and small scale plastic pellet pollution , to large objects such as fishing nets and ...
The hope, officials said, is that the groundbreaking science now underway on the deep-ocean DDT dumping will ultimately inform how future investigations of other offshore dump sites — whether ...

Title I of the Marine Protection, Research and Sanctuaries Act makes it illegal to transport garbage from the United States for the purpose of dumping it into ocean waters without a permit or to dump material from outside the U.S. into U.S. waters.

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.
Shipment of waste from country to country can also involve dumping waste into the ocean. Ocean dumping has been a problem since the 19th century. In the United States, it was legal to dump industrial waste into the ocean until the Ocean Dumping Act was passed in 1972. During the years of 1970 and 1980 alone, it was estimated that 25 million ...
