Maailma l\u00f5pus \u00e4hvardab tohutu pudelikujuline j\u00e4\u00e4m\u00e4gi h\u00e4vitada k\u00f5ik, mis tema teele j\u00e4\u00e4b. Ja ESA kosmosesond Envisat on j\u00e4lginud iga selle liigutust.<\/p>\n<\/div>\n

Igal suvel murduvad Antarktika k\u00fclmast l\u00f5unapooluselt lahti suured ujuvad j\u00e4\u00e4plokid. 2000. aasta m\u00e4rtsis juhtus aga midagi erakordset, kui Ross\u2019i j\u00e4\u00e4massiivist murdus lahti Jamaika suurusega j\u00e4\u00e4plokk.<\/p>\n

J\u00e4rgnevatel aastatel lagunes maailma suurim teadaolev j\u00e4\u00e4m\u00e4gi paljudeks t\u00fckkideks. Suurim t\u00fckk, mida tuntakse nimetusega B-15A, j\u00f5udis l\u00f5puks McMurdo v\u00e4inasse, kus see takistas ookeanivoolusid ja p\u00f5hjustas merej\u00e4\u00e4 kogunemist.<\/p>\n

See tekitas probleeme varustuslaevadele, kes p\u00fc\u00fcdsid j\u00f5uda teadusbaasidesse. Samuti t\u00e4hendas see, et lisandunud merej\u00e4\u00e4 l\u00f5ikas pingviinid \u00e4ra nende tavap\u00e4rastest toitumispaikadest.<\/p>\n

Viimastel n\u00e4dalatel on B-15A j\u00e4rjekindlalt liikunud mere poole ulatuva pika j\u00e4\u00e4keele suunas. Jaanuari alguseks oli vahemaa kahanenud alla 4 km.<\/p>\n

Teadlased ootasid hiiglaste kokkup\u00f5rget, kui B-15A p\u00f5rkas kokku ujuvaga Drygalski j\u00e4\u00e4keelega. Selle asemel n\u00e4is, et j\u00e4\u00e4m\u00e4gi peatus kohapeal ja isegi p\u00f6\u00f6ras veidi tagasi.<\/p>\n

Tundub, et B-15A v\u00f5ib olla madalas meres p\u00f5hja kinni j\u00e4\u00e4nud. Kas tuule, loodete ja p\u00f5hja sulamise m\u00f5ju v\u00f5imaldab sellel l\u00f5puks vabalt ujuma hakata?<\/p>\n

Mis ka ei juhtuks, Envisati radar \u2018n\u00e4eb\u2019 l\u00e4bi Antarktika pilvede, pakkudes teadlastele parimaid vaatamiskohti.<\/p>","protected":false},"excerpt":{"rendered":"
