PARIS: The North Atlantic looks like a rubbish tip, with plastic and polystyrene flotsam spreading far and wide, four French explorers just back from eight months at sea report.Once out of the Breton port of Trinite-sur-Mer in October, they typically spotted at least four to five pieces of rubbish a day – only to sail into a veritable floating dump in April in the Sargasso Sea around Bermuda.”In 15 minutes we saw more garbage than at any time during our journey,” the naval engineer, Yann Geffriaud, 27, said on Saturday a few hours after their return.”It was truly a shock, when in the middle of nowhere we came across 10 to 20 pieces of garbage every five minutes.”The Sargasso Sea, where currents between Florida and Bermuda converge, is named for a brown seaweed – sargassum – that proliferates on its surface, trapping any floating rubbish.”Ninety-five per cent of the stuff is plastics, from toothpaste tubes to aerosol containers and water bottles,” said Mr Geffriaud, the founder of Watch the Waste, a group that asks mariners to monitor rubbish.”Frankly speaking, we did not see a compact area of plastic, but a scattering.”The findings echoed those of the US seafarer and researcher Charles Moore who, two years ago, sailed the Great Pacific Garbage Patch – an estimated 100 million tonnes of rubbish sprawled between Hawaii and Japan.Last February, the US-based Sea Education Association revealed the existence of another virtual island of plastic in the North Atlantic, spread over an area as big as France.Outside the Sargasso Sea, Mr Geffriaud said, the French expedition regularly saw garbage, much of which had been swept from dry land into the ocean by streams and rainfall.”But we saw five times more on the way back, between Bermuda and the Azores, than on the way out along a more southerly track from Cape Verde to Tobago.”Given that we can never clean up the sea, the most simple thing to do is to raise public awareness,” Mr Geffriaud and his team said.Agence France-Presse
