The vast expanse of debris – in effect the world’s largest rubbish dump – is held in place by swirling underwater currents. This drifting ‘soup’ stretches from about 500 nautical miles off the Californian coast, across the northern Pacific, past Hawaii and almost as far as Japan. Charles Moore, an American oceanographer who discovered the ‘Great Pacific Garbage Patch’ or ‘trash vortex’, believes that about 100 million tons of flotsam are circulating in the region. Marcus Eriksen, a research director of the US-based Algalita Marine Research Foundation, which Mr Moore founded, said yesterday: ‘The original idea that people had was that it was an island of plastic garbage that you could almost walk on. It is not quite like that. It is almost like a plastic soup. It is endless for an area that is maybe twice the size as continental United States.’ Curtis Ebbesmeyer, an oceanographer and leading authority on flotsam, has tracked the build-up of plastics in the seas for more than 15 years and compares the trash vortex to a living entity: ‘It moves around like a big animal without a leash.’ When that animal comes close to land, as it does at the Hawaiian […]
