Stvari so se spremenile v za\u010detku leta 2016, ko se je za\u010dela podalj\u0161evati. Samo v januarju 2017 se je podalj\u0161ala za 20 km in dosegla skupno dol\u017eino 175 km. V za\u010detku julija 2017 je bilo med konico razpoke in oceanom le \u0161e nekaj kilometrov. Od takrat znanstveniki \u010dakajo, da bo razpoka dosegla ocean in s tem lo\u010dila ogromen ledeniberg od Antarktike.<\/p>\n<p>Na \u017ealost se Antarktika pribli\u017euje temnim zimskim mesecem, ko je svetlobe malo in je slabo vreme pogosto, kar ote\u017euje opazovanje celo s sateliti. Da bi premagali to te\u017eavo, so znanstveniki iz projekta MIDAS, antarkti\u010dne raziskovalne skupine pod vodstvom Univerze v Swansea v Veliki Britaniji, uporabili radarsko opremo satelitov Sentinel, da so lahko videli skozi temo in oblake.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1500\" data-credit=\"P.

CryoSat je opremljen z napravo, imenovano radarski vi\u0161inomer, ki lahko meri vi\u0161ino in debelino ledu. Ta nam je pokazal, da je bila razpoka globoka ve\u010d deset metrov in da ni \u0161lo le za plitvo razpoko na povr\u0161ini.<\/p>\n<p>Ta novi ogromni ledeniberg meri pribli\u017eno 6000 kvadratnih kilometrov in tehta ve\u010d kot milijon milijonov ton! Te\u017eko je napovedati, kaj se bo z njim zgodilo v prihodnosti. Morda bo \u0161e dolga leta plaval v tem obmo\u010dju. Ali pa se bo razdelil na manj\u0161e ledenibergove, ki bi lahko odpluli proti severu v toplej\u0161e vode, kjer bi se led stopil.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1500\" data-credit=\"ESA\u2013Pierre\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2017\/07\/Artist_s_impression_of_Sentinel-1B\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2017\/07\/artist_s_impression_of_sentinel-1b\/17899311-2-eng-GB\/Artist_s_impression_of_Sentinel-1B.jpg\" alt=\"Artist\u2019s impression of Sentinel-1B\"><figcaption>Umetni\u0161ka upodobitev satelita Sentinel-1B<\/figcaption><\/figure>\n<p>\u010ce bi Antarktika izgubila tako velik del ledu, bi to lahko povzro\u010dilo te\u017eave.
