Plastic missing in the Ocean

Die gestern veröffentlichte Studie Plastic debris in the open ocean besagt zwei Dinge: 1.) 88% der globalen Meeresoberfläche enthält Plastik und 2.) das ist bei weitem (97-99%) nicht genug. Wissenschaftler gingen davon aus, dass sie rund 1 Millionen Tonnen hätten finden müssten, stattdessen fanden sie nur zwischen mageren 7 bis 35000 (die hochgerechnete Zahl variiert anscheinend nach lokal abgefischten Plastikmengen). Die Lösung: Fische fressen das Plastik, das auf diesem Weg wieder in der Nahrungskette und im Sushi landet. Guten Appetit.

The results of the study “Plastic debris in the open ocean” are based on 3,070 total ocean samples collected around the world by Spain’s Malaspina science expedition in 2010. […] The total amount of plastic in the open-ocean surface is estimated at between 7,000 and 35,000 tons, according to the report. This amount, though big, is lower than the scientists expected. […]

However, the study raised several new concerns including those about the fate of so much plastic, particularly the smallest pieces. The research found that plastic fragments "between a few microns and a few milimeters in size are underrepresented in the ocean surface samples." […] "Ocean currents carry plastic objects which split into smaller and smaller fragments due to solar radiation," says Cozar. "These micro plastics have an influence on the behavior and the food chain of marine organisms."
