Yanl\u0131\u015f rotadan kritik ke\u015fifler ortaya \u00e7\u0131kt\u0131<\/b><\/p>\n

Olay\u0131n ba\u015flang\u0131c\u0131 2020 y\u0131l\u0131na uzan\u0131yor. Avustralya Ulusal Bilim Ajans\u0131 CSIRO<\/strong>, Do\u011fu Antarktika\u2019daki Totten Buzulu<\/strong> yak\u0131nlar\u0131nda bir Argo tipi okyanus robotunu g\u00f6revlendirdi. Serbest dola\u015fan bu robot, deniz suyunun s\u0131cakl\u0131k ve tuzluluk de\u011ferlerini \u00f6l\u00e7ebilen sens\u00f6rlerle donat\u0131lm\u0131\u015ft\u0131. Normal \u015fartlarda her 10 g\u00fcnde bir y\u00fczeye \u00e7\u0131karak toplad\u0131\u011f\u0131 verileri uydular arac\u0131l\u0131\u011f\u0131yla merkeze iletmesi planlan\u0131yordu. Bu g\u00f6revdeki temel ama\u00e7, Totten Buzulu\u2019nun erimesi halinde k\u00fcresel deniz seviyelerinin ne kadar y\u00fckselebilece\u011fini daha net bi\u00e7imde ortaya koymakt\u0131.<\/p>\n

Ancak Antarktika\u2019ya \u00f6zg\u00fc g\u00fc\u00e7l\u00fc ve de\u011fi\u015fken okyanus ak\u0131nt\u0131lar\u0131, robotu planlanan rotas\u0131ndan sapt\u0131rd\u0131.

Y\u00fczeye \u00e7\u0131kamayan robot uzun s\u00fcre boyunca kay\u0131p olarak kabul edildi ve g\u00f6revin ba\u015far\u0131s\u0131z oldu\u011fu d\u00fc\u015f\u00fcn\u00fcld\u00fc.<\/p>\n

<\/span> Aylar sonra ortaya \u00e7\u0131kan bulgular, robotun bu s\u00fcre boyunca tamamen i\u015flevsiz kalmad\u0131\u011f\u0131n\u0131 g\u00f6sterdi.

Y\u00fczeye \u00e7\u0131k\u0131p veri aktaramasa da, y\u00fckselme denemeleri s\u0131ras\u0131nda buz raf\u0131na her \u00e7arpt\u0131\u011f\u0131nda buz taban\u0131n\u0131n derinli\u011fini \u00f6l\u00e7ebildi. Bu temaslar, ara\u015ft\u0131rmac\u0131lar i\u00e7in robotun konumunu anlamada kritik ipu\u00e7lar\u0131 sa\u011flad\u0131. <\/figure>\n

Buz sahanl\u0131klar\u0131, Antarktika\u2019daki buzullar\u0131 okyanustan k\u0131smen izole eden, devasa y\u00fczen buz platformlar\u0131 olarak biliniyor. Bu yap\u0131lar, buzullar\u0131n h\u0131zla eriyerek denize kar\u0131\u015fmas\u0131n\u0131 yava\u015flatan do\u011fal bir tampon g\u00f6revi g\u00f6r\u00fcyor. Ancak okyanus sular\u0131n\u0131n \u0131s\u0131nmas\u0131, \u0131l\u0131k su k\u00fctlelerinin buz sahanl\u0131klar\u0131n\u0131n alt\u0131na s\u0131zmas\u0131na neden oluyor. Bu s\u00fcre\u00e7, tabandan erimeyi h\u0131zland\u0131rarak daha fazla buzun okyanusa kar\u0131\u015fmas\u0131na ve deniz seviyelerinin y\u00fckselmesine yol a\u00e7abiliyor. Kal\u0131nl\u0131klar\u0131 y\u00fczlerce hatta binlerce metreyi bulabilen bu yap\u0131lar\u0131 do\u011frudan incelemek ise son derece zor.<\/p>\n

Deniz seviyeleri i\u00e7in kritik uyar\u0131<\/b><\/p>\n

<\/span> Ara\u015ft\u0131rma ekibi, robotun toplad\u0131\u011f\u0131 verileri uydu \u00f6l\u00e7\u00fcmleriyle kar\u015f\u0131la\u015ft\u0131rarak izledi\u011fi g\u00fczergah\u0131 ad\u0131m ad\u0131m yeniden olu\u015fturdu.

G\u00f6rev s\u00fcresince robotun toplam 195 ayr\u0131 veri profili<\/strong> toplad\u0131\u011f\u0131 belirlendi. <\/figure>\n

Elde edilen sonu\u00e7lar, Shackleton Buz Sahanl\u0131\u011f\u0131\u2019n\u0131n \u015fu a\u015famada \u0131l\u0131k sular nedeniyle ciddi bir erime riski alt\u0131nda olmad\u0131\u011f\u0131n\u0131 ortaya koydu. Ancak Denman Buzulu<\/strong> i\u00e7in tablo \u00e7ok daha endi\u015fe verici<\/strong>. \u00d6l\u00e7\u00fcmler, buzulun alt\u0131nda s\u0131cak su k\u00fctlelerinin bulundu\u011funu ve bunun erime s\u00fcrecini h\u0131zland\u0131rd\u0131\u011f\u0131n\u0131 g\u00f6sterdi. Bilim insanlar\u0131na g\u00f6re Denman Buzulu\u2019nun tamamen erimesi, d\u00fcnya genelinde deniz seviyelerinin yakla\u015f\u0131k 152 santimetre y\u00fckselmesine<\/strong> neden olabilecek potansiyele sahip.<\/p>\n

Uzmanlar, bu t\u00fcr riskli b\u00f6lgelerin erken tespit edilmesinin, iklim de\u011fi\u015fikli\u011finde baz\u0131 geri d\u00f6n\u00fc\u015fs\u00fcz e\u015fiklerin a\u015f\u0131lm\u0131\u015f olabilece\u011fine i\u015faret etti\u011fini vurguluyor. Al\u0131nacak t\u00fcm \u00f6nlemlere ra\u011fmen, k\u00fcresel k\u0131y\u0131 \u015feritlerinin ciddi bir tehdit alt\u0131nda olabilece\u011fi ifade ediliyor.<\/p>\n\n
