\u00d6ljy on olennainen osa nykyaikaista el\u00e4m\u00e4\u00e4. Ilman t\u00e4t\u00e4 arvokasta polttoainetta autot ja kuorma-autot eiv\u00e4t p\u00e4\u00e4sisi liikenteeseen, lentokoneet eiv\u00e4t voisi lent\u00e4\u00e4 ja monet teollisuudenalat pys\u00e4htyisiv\u00e4t kokonaan. \u00d6ljy voi kuitenkin olla my\u00f6s uhka luonnolle, jos sit\u00e4 ei k\u00e4sitell\u00e4 asianmukaisesti. \u00d6ljyvuodot voivat levit\u00e4 valtaville merialueille. Ruskeat \u00f6ljylautat peitt\u00e4v\u00e4t kaiken, mihin ne koskettavat, tarttuvalla limalla, tappavat monia lintuja ja merenel\u00e4vi\u00e4 sek\u00e4 peitt\u00e4v\u00e4t hiekkarannat ja koralliriutat.<\/p>\n<\/div>\n

Viimeisin \u00f6ljykatastrofi alkoi 22. huhtikuuta 2010, kun porauslautta r\u00e4j\u00e4hti ja upposi Meksikonlahdella. Siit\u00e4 l\u00e4htien merenpohjassa sijaitsevasta vaurioituneesta \u00f6ljyl\u00e4hteest\u00e4 on vuotanut miljoonia tynnyreit\u00e4 raaka\u00f6ljy\u00e4, mik\u00e4 uhkaa aiheuttaa mittavan ymp\u00e4rist\u00f6katastrofin.<\/p>\n

Ruskean hirvi\u00f6n levi\u00e4mist\u00e4 on seurattu useiden satelliittien avulla, muun muassa ESA:n Envisat-satelliitin avulla. N\u00e4m\u00e4 \u2018avaruuden silm\u00e4t\u2019 tarjoavat v\u00e4ltt\u00e4m\u00e4t\u00f6nt\u00e4 ja ajantasaista tietoa tuhansille virkamiehille sek\u00e4 lukuisille ihmisille, jotka saavat elantonsa kalastuksesta ja matkailusta.<\/p>\n

Avaruusaluksen optiset laitteet havaitsevat \u00f6ljylautan p\u00e4iv\u00e4ll\u00e4, kun alue on pilvet\u00f6n. Tutkalaitteet pystyv\u00e4t havaitsemaan \u00f6ljykerroksen y\u00f6ll\u00e4 ja pilvien alla. Meriaaltoja ja merivirtauksia koskevien tietojen avulla on my\u00f6s mahdollista laskea, miten pilaantuminen saattaa levit\u00e4.<\/p>\n

Kuvista n\u00e4kyy, ett\u00e4 \u00f6ljy on j\u00e4\u00e4nyt py\u00f6re\u00e4\u00e4n virtaukseen, joka pit\u00e4\u00e4 sen \u2013 ainakin toistaiseksi \u2013 kaukana suurimmasta osasta Floridaa. Samaan aikaan hurrikaanikausi on alkanut, ja satelliitit tarkkailevat voimakkaita myrskyj\u00e4, jotka viiv\u00e4stytt\u00e4v\u00e4t vuotojen pysyv\u00e4\u00e4 tukkimista.<\/p>","protected":false},"excerpt":{"rendered":"
