I-Totten Glacier yeyona inkulu kwimpuma ye-Antarctica kwaye incibilikisi yayo iyakhawuleza ngenxa yokunyuka kwemimoya kuLwandlekazi lwaseMazantsi. Ngobushushu behlabathi, umkhenkce osemkhenkceni uyanyibilika ngesantya esikhula ngokukhawuleza kwaye ukuba sidibanisa nale imimoya ibasa emanzini ashushu, unyibiliko lwabo luya kwenzeka msinyane.
Ngaba uyafuna ukwazi imeko yeGlacier yaseTotten?
I-glacier Totten inyibilika ngokukhawuleza
Inkqubo yeAustralia yeAntarctic iqhubeka ngokujonga imeko yomkhenkce waseAntarctic. I-Totten Glacier yeyona inkulu kwimpuma ye-Antarctica kwaye ukunyibilika kwayo kuya kusanda kubhengezwa, ngenxa imimoya ibhudla ngamandla kwaye ityhalela kumanzi ashushu aselunxwemeni lweAntarctic angena ezantsi kwenxalenye edadayo yomkhenkce.
Ukungena ngokuqhubekayo kwamanzi ashushu kwindawo edadayo yomkhenkce iyenza inyibilike ngokukhawuleza. Esi sigqibo sisekwe kwindibaniselwano yemifanekiso yesathelayithi, idatha yomoya, kunye nokuqwalaselwa kolwandle. Kucacile ukuba indawo esezantsi inyibilika njani ngokukhawuleza kwaye ikhawulezise ukuhamba komkhenkce ukuya elwandle.
“Umsebenzi wethu unika ubungqina boqhagamshelo loomatshini ku Ukuhambisa ubushushu Ukusuka kwiatmosfera elwandle ukuya kutsho emkhenkceni, utshilo omnye wabaphandi, uDavid Gwyther, osuka kwiYunivesithi yaseTasmania, kwingxelo.
Ngenxa yotshintsho lwemozulu, isantya somoya siyatshintsha kuLwandlekazi lwaseMazantsi kwaye oku kuqikelelwa ukuba kukonyuka ngakumbi nangakumbi, ke ngoko, iTalk glacier iya kunyibilika ngokukhawuleza, inegalelo kunyuko lwehlabathi kulwandle.
Umoya onamandla kunye namanzi ashushu
Izinto ezichaphazela ukunyibilika komkhenkce ngumoya kunye nobushushu bamanzi. Ngamaxesha apho umoya unamandla ngakumbi, amanzi aphezu komhlaba ayemka aze athatyathelwe indawo ngamanzi anzulu kwaye ashushu, ukuze kuthi xa kuchaphazela amaqhekeza omkhenkce, akhawuleze ukunyibilika kwawo.
Umkhenkce ukhupha iikhilomitha ezisisi-538.000 kwimpuma ye-Antarctica kunye ulahla i-70.000 yezigidi zeetoni zomkhenkce minyaka le, ngokwenqaku laseAustralia leAntarctic.
