L\u00e4ngst ner p\u00e5 jorden har ett enormt, flaskformat isberg hotat att \u00f6del\u00e4gga allt i sin v\u00e4g. Och ESA:s rymdsond Envisat har f\u00f6ljt varje r\u00f6relse.<\/p>\n<\/div>\n

Varje sommar bryts stora bitar av flytande is loss fr\u00e5n den kalla s\u00f6dra kontinenten Antarktis. I mars 2000 intr\u00e4ffade dock n\u00e5got speciellt n\u00e4r en isblock stor som Jamaica br\u00f6ts loss fr\u00e5n Ross-isshelfen.<\/p>\n

Under de f\u00f6ljande \u00e5ren splittrades v\u00e4rldens st\u00f6rsta k\u00e4nda isberg i m\u00e5nga bitar. Den st\u00f6rsta isbiten, k\u00e4nd som B-15A, drev s\u00e5 sm\u00e5ningom in i McMurdo-sundet, d\u00e4r den blockerade havsstr\u00f6mmarna och ledde till att havsisen byggdes upp.<\/p>\n

Detta skapade problem f\u00f6r f\u00f6rs\u00f6rjningsfartyg som f\u00f6rs\u00f6kte ta sig fram till forskningsstationerna. Det innebar ocks\u00e5 att den extra havsisen hindrade pingvinerna fr\u00e5n att n\u00e5 sina vanliga f\u00f6doomr\u00e5den.<\/p>\n

Under de senaste veckorna har B-15A stadigt r\u00f6rt sig mot en l\u00e5ng istunga som str\u00e4cker sig ut i havet. I b\u00f6rjan av januari hade avst\u00e5ndet minskat till mindre \u00e4n 4 km.<\/p>\n

Forskarna f\u00f6rv\u00e4ntade sig att f\u00e5 bevittna en kollision mellan j\u00e4ttar n\u00e4r B-15A kraschade in i den flytande Drygalski-istungan. Ist\u00e4llet verkade isberget stanna upp och till och med v\u00e4nda n\u00e5got.<\/p>\n

Det verkar som om B-15A kan ha fastnat p\u00e5 botten i det grunda havet. Kommer p\u00e5verkan fr\u00e5n vind, tidvatten och sm\u00e4ltande botten s\u00e5 sm\u00e5ningom att g\u00f6ra att den flyter loss?<\/p>\n

Oavsett vad som h\u00e4nder kommer Envisats radar att \u2018se\u2019 genom molnen \u00f6ver Antarktis och ge forskarna en plats p\u00e5 f\u00f6rsta parkett.<\/p>","protected":false},"excerpt":{"rendered":"
