D\u00fcnyan\u0131n en b\u00fcy\u00fck buz da\u011f\u0131 olarak bilinen “A23a” Atlantik Okyanusu’nda karaya oturdu.<\/p>\n
BBC’nin haberine nazaran, uydu imajlar\u0131, d\u00fcnyadaki en b\u00fcy\u00fck buz da\u011f\u0131 olarak bilinen “A23a” ile ilgili yeni durumunu ortaya \u00e7\u0131kard\u0131.<\/p>\n
Buna nazaran, A23a, South Georgia Adas\u0131 a\u00e7\u0131klar\u0131nda, karadan 80 km uzakl\u0131ktaki s\u0131\u011f k\u0131ta sahanl\u0131\u011f\u0131na \u00e7arparak karaya oturdu ve s\u0131k\u0131\u015f\u0131p kald\u0131.<\/p>\n
B\u00fcy\u00fck \u00f6l\u00e7\u00fcde besin hususuna sahip buz da\u011f\u0131n\u0131n, par\u00e7alan\u0131p erimesiyle, okyanusta hayat patlamas\u0131na neden olabilece\u011fi sav ediliyor.<\/p>\n
\u0130ngiltere ulusal kutup ara\u015ft\u0131rma enstit\u00fcs\u00fc “British Antarctic Survey” uzman\u0131 Prof. Nadine Johnston, “Bu (durum), bo\u015f bir \u00e7\u00f6l\u00fcn ortas\u0131na besin bombas\u0131 atmak \u00fczere bir \u015fey” tabirini kulland\u0131.<\/p>\n
South Georgia h\u00fck\u00fcmetine dan\u0131\u015fmanl\u0131k yapan ekolojist Mark Belchier ise, “(Buzul k\u00fctle) \u015eayet par\u00e7alan\u0131rsa, ortaya \u00e7\u0131kan buzda\u011flar\u0131, lokal ak\u0131nt\u0131larda hareket eden gemiler i\u00e7in tehlike olu\u015fturabilir ve gemilerin mahall\u00ee bal\u0131k\u00e7\u0131l\u0131k alanlar\u0131na eri\u015fimini k\u0131s\u0131tlayabilir.” dedi.<\/p>\n

Antarktika’da bulunan “RRS Sir David Attenborough” kutup ara\u015ft\u0131rma gemisinde misyonlu Prof. Huw Griffiths da, “T\u00fcm buzda\u011flar\u0131n\u0131n gelece\u011fi \u00f6lecekleri taraf\u0131nda. A23a’n\u0131n bu kadar uzun m\u00fchlet dayanmas\u0131 ve alan\u0131n\u0131n s\u0131rf d\u00f6rtte birini kaybetmesi \u00e7ok \u015fa\u015f\u0131rt\u0131c\u0131” diye konu\u015ftu.<\/p>\n
Buzulun b\u00f6lge ekosistemine takviyesine dikkati \u00e7eken Griffiths, \u015funlar\u0131 s\u00f6yledi:<\/p>\n
“T\u00fcm cihan, deniz taban\u0131nda kaz\u0131nan devasa bir buz mod\u00fcl\u00fc taraf\u0131ndan eziliyor. Bir yerde bir \u015feyi yok ederken, \u00f6teki yerlerde besin ve yiyecek sa\u011fl\u0131yor. Buz olmasayd\u0131 bu ekosistemlere sahip olamazd\u0131k. Bunlar d\u00fcnyadaki en \u00fcretken ekosistemlerden kimileri ve \u00e7ok say\u0131da cinse ve ki\u015fisel hayvana takviye sa\u011fl\u0131yor ve mavi balina \u00fczere d\u00fcnyan\u0131n en b\u00fcy\u00fck hayvanlar\u0131n\u0131 besliyor.”<\/p>\n
