Miljontals m\u00e4nniskor i s\u00f6dra USA f\u00f6ljer med sp\u00e4nning hur ett enormt, brunt monster virvlar runt ute till havs och f\u00f6rbereder sig f\u00f6r att dr\u00e4nka den n\u00e4rliggande kusten. Monstret i fr\u00e5ga \u00e4r en enorm oljefl\u00e4ck som driver omkring i vindarnas och havsstr\u00f6mmarnas v\u00e5ld. Om den n\u00e5r land kommer viktiga fiskeomr\u00e5den, turiststr\u00e4nder och fortplantningsomr\u00e5den f\u00f6r vilda djur att begravas under tjockt, klibbigt slam. En stor milj\u00f6katastrof hotar.<\/p>\n<\/div>\n

Optiska instrument ombord p\u00e5 satelliterna kan uppt\u00e4cka oljeutsl\u00e4ppet p\u00e5 ytan under dagtid, n\u00e4r omr\u00e5det \u00e4r molnfritt. Radarinstrument kan se oljefl\u00e4cken p\u00e5 natten och under molnt\u00e4cke, samtidigt som de ger information om ytans oj\u00e4mnheter och str\u00f6mf\u00f6rh\u00e5llandena. Detta g\u00f6r det m\u00f6jligt att ber\u00e4kna i vilken riktning f\u00f6roreningen kan sprida sig.<\/p>\n

Krisen inleddes den 22 april, efter att en borrplattform exploderade och sj\u00f6nk i Mexikanska golfen. Sedan dess har tusentals fat r\u00e5olja l\u00e4ckt ut varje dag fr\u00e5n en skadad oljek\u00e4lla, 1,5 km under borrplattformen. Inom fyra dagar hade oljeutsl\u00e4ppet spridit sig \u00f6ver ett omr\u00e5de som var 77 km l\u00e5ngt och 63 km brett. Inledningsvis visade satellitbilder att oljan drevs mot Louisianas kust, men lyckligtvis v\u00e4nde vinden och oljefl\u00e4cken har huvudsakligen stannat kvar p\u00e5 \u00f6ppet hav.<\/p>\n

Bilder fr\u00e5n rymden visar dock nu en l\u00e5ng oljetunga som sprider sig s\u00f6derut. Den 19 maj visade radarbilder fr\u00e5n Envisat att den hade kommit in i en kraftig havsstr\u00f6m som kunde f\u00f6ra oljan s\u00f6derut mot Floridas vackra korallrev.<\/p>","protected":false},"excerpt":{"rendered":"
