A mintegy 4000 n\u00e9gyzetkilom\u00e9ter ter\u00fclet\u0171 A23a elnevez\u00e9s\u0171 j\u00e9ghegy 1986-ban v\u00e1lt le az Antarktisz partjair\u00f3l. Hamarosan megfeneklett a Weddell-tengeren, \u00e9s \u201ej\u00e9gsziget\u201d lett bel\u0151le.<\/p>\n\n\n\n

A 400 m\u00e9ter vastag j\u00e9gt\u00e1bla az elm\u00falt \u00e9vben kezdett egyre gyorsabban sodr\u00f3dni, \u00e9s hamarosan az antarktiszi vizeken k\u00edv\u00fclre ker\u00fclhet.<\/p>\n\n\n

Az A23a az Antarktisz Filchner-selfj\u00e9g t\u00e1bl\u00e1j\u00e1r\u00f3l szakadt le m\u00e1s j\u00e9ghegyekkel egy\u00fctt. A nyolcvanas \u00e9vekben az A23a ter\u00fclet\u00e9n m\u00e9g egy szovjet kutat\u00f3\u00e1llom\u00e1s m\u0171k\u00f6d\u00f6tt. Miut\u00e1n a j\u00e9ghegy leszakadt, exped\u00edci\u00f3t k\u00fcldtek az \u00e1llom\u00e1sra a felszerel\u00e9sek elsz\u00e1ll\u00edt\u00e1s\u00e1ra, hogy ne vesszenek oda. A j\u00e9ghegy azonban nem jutott messzire, mert m\u00e9lyre mer\u00fcl\u0151 alja bele\u00fctk\u00f6z\u00f6tt \u00e9s fennakadt a Weddell-tenger medr\u00e9ben.<\/p>\n\n\n\n

Andrew Fleming, a Brit Antarktisz-kutat\u00f3 Int\u00e9zet szak\u00e9rt\u0151je elmondta, hogy el\u0151sz\u00f6r 2020-ban \u00e9rz\u00e9kelt\u00e9k a j\u00e9ghegy elmozdul\u00e1s\u00e1t. Mint hozz\u00e1tette: a kutat\u00f3k \u00fagy v\u00e9lik, az\u00e9rt indulhatott \u00fatnak, mert mostan\u00e1ra cs\u00f6kkent le a m\u00e9rete annyira, hogy ez megt\u00f6rt\u00e9nhetett.<\/p>\n\n\n\n

Az A23a halad\u00e1sa az ut\u00f3bbi h\u00f3napokban a sz\u00e9l \u00e9s az \u00e1ramlatok hat\u00e1s\u00e1ra gyorsult fel, \u00e9s jelenleg az Antarktiszi-f\u00e9lsziget \u00e9szaki cs\u00facsa f\u00f6l\u00f6tt j\u00e1r.<\/p>\n\n\n\n

A tud\u00f3sok szerint a Weddell-tengerr\u0151l \u00e9rkez\u0151 j\u00e9ghegyekhez hasonl\u00f3an feltehet\u0151en az A23a is beker\u00fcl az antarktiszi sarkvid\u00e9ki \u00e1ramlatba, \u00e9s az Atlanti-\u00f3ce\u00e1n d\u00e9li r\u00e9sze fel\u00e9 fog sodr\u00f3dni. A tud\u00f3sok tov\u00e1bbra is figyelik az A23a sors\u00e1t.<\/p>\n\n\n\n
