<\/p>\nSon y\u0131llarda yap\u0131lan ara\u015ft\u0131rmalar, bu “buz-okyanus hudut tabakas\u0131” hakk\u0131nda yeni bilgiler sunarak, Antarktika\u2019n\u0131n erime s\u00fcrecine \u0131\u015f\u0131k tutuyor.<\/p>\n
Antarktika\u2019n\u0131n buz katman\u0131, ortalama 2 kilometre kal\u0131nl\u0131\u011fa ve Avustralya\u2019n\u0131n iki kat\u0131 b\u00fcy\u00fckl\u00fc\u011f\u00fcnde bir alana sahip. Bu devasa buz k\u00fctlesi, gere\u011fince tatl\u0131 su i\u00e7ererek deniz d\u00fczeyini 58 metre y\u00fckseltebilir.\u00a0<\/p>\n
Ancak, bu buz katman\u0131n\u0131n deniz d\u00fczeyine tesiri hala me\u00e7huld\u00fcr; projeksiyonlar, 2100 y\u0131l\u0131na kadar 44 cm\u2019lik bir y\u00fckseli\u015ften 22 cm\u2019lik bir d\u00fc\u015f\u00fc\u015fe kadar de\u011fi\u015fen \u00f6ng\u00f6r\u00fcler sunmakta.<\/p>\n
Antarktika\u2019n\u0131n kenar\u0131ndaki buzullar, G\u00fcney Okyanusu\u2019na akarak devasa buz raflar\u0131 olu\u015fturuyor. Bu buz raflar\u0131, okyanus suyunun alttan eritti\u011fi bir s\u00fcre\u00e7 olan “temel erime” nedeniyle inceliyor ve geri \u00e7ekiliyor.\u00a0<\/p>\n
Bu erime, sadece buz katman\u0131n\u0131 istikrars\u0131zla\u015ft\u0131rmakla kalm\u0131yor, t\u0131pk\u0131 vakitte d\u00fcnya genelinde su deveran\u0131n\u0131 sa\u011flayan en derin ak\u0131nt\u0131lardan birini yava\u015flat\u0131yor.<\/p>\n
Eriyen buz raflar\u0131n\u0131n denetimi, okyanus ak\u0131nt\u0131lar\u0131, s\u0131cakl\u0131k, tuz oran\u0131 ve buzun bi\u00e7imi \u00fczere bir\u00e7ok mikro \u00f6l\u00e7ekli fakt\u00f6re ba\u011fl\u0131.\u00a0<\/p>\n
<\/p>\n
Bu hudut katman\u0131, buz raf\u0131n\u0131n alt\u0131nda yaln\u0131zca milimetre \u00f6l\u00e7e\u011finde bir katman olu\u015fturur ve bu nedenle \u00f6l\u00e7\u00fclmesi ve modellenmesi son derece zordur. Lakin geli\u015fen bilgisayar sim\u00fclasyonlar\u0131, bu sondaki s\u00fcre\u00e7leri daha \u00e2l\u00e2 anlamam\u0131za yard\u0131mc\u0131 oluyor.<\/p>\n
Son y\u0131llarda kullan\u0131lan otonom deniz alt\u0131 robotlar\u0131 ve sondalar, buz raflar\u0131n\u0131n alt\u0131nda daha evvel g\u00f6r\u00fclmemi\u015f bilgiler sunuyor. Sonar ve kameralarla donat\u0131lm\u0131\u015f bu robotlar, erimenin farkl\u0131 b\u00f6lgelerde nas\u0131l ger\u00e7ekle\u015fti\u011fini ortaya \u00e7\u0131kar\u0131yor.\u00a0<\/p>\n
\u00d6rne\u011fin, Bat\u0131 Antarktika\u2019daki Dotson Buz Raf\u0131\u2019n\u0131n do\u011fusunda s\u0131cak ve sakin sularda olu\u015fan teraslar g\u00f6zlemlenirken, so\u011fuk ve s\u00fcratli ak\u0131nt\u0131lar\u0131n oldu\u011fu bat\u0131 b\u00f6lgesinde midye bi\u00e7imindeki erime oyuklar\u0131 ke\u015ffedildi.<\/p>\n
Ara\u015ft\u0131rmac\u0131lar, erimenin s\u0131rf okyanus s\u0131cakl\u0131\u011f\u0131na de\u011fil, t\u0131pk\u0131 vakitte buzun e\u011fimine ve okyanus ak\u0131nt\u0131lar\u0131n\u0131n surat\u0131na da ba\u011fl\u0131 oldu\u011funu belirtiyor.<\/p>\n
Dik e\u011fimli buz y\u00fczeyleri, erime suyunun daha fazla kar\u0131\u015fmas\u0131na neden olarak erime surat\u0131n\u0131 art\u0131r\u0131yor. Bu s\u00fcre\u00e7, \u00e7\u00f6l kumullar\u0131n\u0131n hareketine benzeri halde “kendi kendini \u015fekillendirme” davran\u0131\u015f\u0131n\u0131 g\u00f6steriyor.
