Nederst p\u00e5 jorden har et k\u00e6mpe, flaskeformet isbjerg truet med at \u00f8del\u00e6gge alt p\u00e5 sin vej. Og ESA\u2019s Envisat-rumfart\u00f8j har fulgt hver eneste bev\u00e6gelse.<\/p>\n<\/div>\n

Hver sommer bryder der enorme stykker drivende is af fra det kolde sydlige kontinent, Antarktis. I marts 2000 skete der imidlertid noget helt s\u00e6rligt, da en isblok p\u00e5 st\u00f8rrelse med Jamaica br\u00f8d af fra Ross-isbr\u00e6en.<\/p>\n

I l\u00f8bet af de f\u00f8lgende \u00e5r br\u00f8d verdens st\u00f8rste kendte isbjerg op i mange stykker. Den st\u00f8rste isblok, kendt som B-15A, drev til sidst ind i McMurdo-sundet, hvor den blokerede havstr\u00f8mmene og f\u00f8rte til en ophobning af havis.<\/p>\n

Dette skabte problemer for forsyningsskibe, der fors\u00f8gte at n\u00e5 frem til forskningsstationerne. Det bet\u00f8d ogs\u00e5, at den ekstra havis afskar pingvinerne fra deres s\u00e6dvanlige f\u00f8deomr\u00e5der.<\/p>\n

I de seneste uger har B-15A st\u00f8t bev\u00e6get sig mod en lang istunge, der rager ud i havet. I begyndelsen af januar var afstanden indsn\u00e6vret til under 4 km.<\/p>\n

Forskerne havde forventet at se en kollision mellem to k\u00e6mper, da B-15A st\u00f8dte ind i den flydende Drygalski-istunge. I stedet s\u00e5 det ud til, at isbjerget standsede op og endda vendte lidt om.<\/p>\n

Det ser ud til, at B-15A muligvis ligger fast p\u00e5 bunden i det lavvandede hav. Vil p\u00e5virkningen fra vind, tidevand og smeltning af havbunden i sidste ende f\u00e5 den til at flyde fri?<\/p>\n

Uanset hvad der sker, vil Envisats radarsyn \u2018se\u2019 igennem de antarktiske skyer og give forskerne en plads p\u00e5 f\u00f8rste parket.<\/p>","protected":false},"excerpt":{"rendered":"
