Ukuba ukhe wanethuba lokuya kwindawo ebandayo njengelizwekazi laseAntarctic, kwaye ukuba ungazama ukungena emanzini, lumka kakhulu. Kusenokwenzeka ukuba uhlangane neenkanyamba zolwandle, ezaziwa ngegama lika ingca, okanye ingalo yokufa.
Yimbonakalo emangalisayo yendalo, mhlawumbi eyona nto imangalisayo kuzo zonke ezenzeka elwandle. Ngaba uyafuna ukwazi ukuba yenziwa njani?
Kwiplanethi yoMhlaba, ayikaziwa yonke into okwangoku, kwaye enyanisweni, bekungekho ngo-1960 apho kwakusaziwa ukuba i-brinicle ikhona ngokwenene, kwaye ngo-2011 yafotwa okokuqala ngqa emva kwexesha. Kodwa yintoni leyo? Ewe, le nto inomdla wokwenyani yi-ice stalactite eyenzeka emanzini ase-Antarctica ngenxa yomahluko kumaqondo obushushu aphezu komhlaba (ajikeleze -20ºC) nakwinzulu (ukusuka - I-2 ° C). Yiyo loo nto ukuhamba kwamanzi anetyuwa, obushushu bawo bungaphantsi kweqondo, kudibana namanzi olwandle, afudumeleyo, kwaye ngenxa yoko i-ice stalactite yenziwa.
Ekuqaleni ikhumbuza kakhulu ityhubhu engenamanzi yomkhenkce ekhula iye ezantsi. Ngaphakathi kwayo kukho amanzi athi kubanda kakhulu kwaye inexinano eninzi yetyuwa, eqokelela kumajelo. Kweli nqanaba kukwenziwa kobuthathaka, kuba iindonga zibhityile kwaye kufuneka "zondle" ityuwa ukuze iqhubeke nokukhula. Nangona kunjalo, ukuze kwenzeke oku, iimeko mazibe zezi zilandelayo:
- Amanzi ajikeleze ityhubhu kufuneka abemncinci ityuwa encinci kunaleyo ingaphakathi kuyo.
- Amanzi ayinakuba nzulu kakhulu.
- Amanzi akule ndawo kufuneka agcinwe cwaka.
Ukuba iimeko zilungile, ungaya emazantsi kwaye uhambe indlela ende yokuhla. Ngeli xesha, izakushiya iwebhu yomkhenkce eya kwenza eyona nto iyenzayo: iqandusele yonke into esemendweni wayo, nokuba ziinkwenkwezi okanye iiurchins zaselwandle, iintlanzi, oononkala… nantoni na. Ngaphandle koko, ngokulula iya kutshabalala.
Ngapha koko, "ingalo" iyabanda kwaye inde kangangokuba xa ihambela phambili ayilahli uzinzo, yiyo loo nto igcina ukumila kwayo kwaye inyusa ubungakanani xa ingena elwandle, njengoko inengubo yokwambathisa eyenziwe yijethi amanzi abandayo anetyuwa ehla ezantsi. Olu luhlu luyaluthintela ekufudumaleni, ngenxa yoko luya kuqhubeka ukwehla kwaye lenze ngakumbi umkhenkce. Kungenxa yokuba ityuwa ibangela indawo ebandayo ukuba yehle… ngaphezulu. Ke, i-brinicle iya isomelela, iyamangalisa ngakumbi ukuba kunokwenzeka.
Kwaye ityuwa, ngelixa ibhranti iyaqhubeka nokubanda, iphuma kulwakhiwo, ibangela ukuba amanzi angqongileyo abe netyuwa eninzi. Kunokuthiwa, kwaye asinakuphazama, ukuba le nto "ityisa" ityuwa, kaninzi umjikelo ubuya kuphinda uqhubeke ... de kubekho utshintsho olukhulu kubushushu okanye kubunzulu bolwandle.
Ubungakanani bebrinicle ngu limited. Kuya kuxhomekeka kumanzi awungqongileyo, ubunzulu bamanzi, kunye nokukhula komkhenkce onayo okanye omnye. Kukho nawuphi na, kuyamangalisa.
Olu qulunqo lwashicilelwa okokuqala ngo-2011, eRazorback Island, e-Antarctica, nguKathryn Jeffs kunye neekhamera uHugh Miller noDoug Anderson be-BBC. Iqondo lobushushu elwandle lalijikeleze i-2ºC, kodwa baba nesibindi sokuntywila ngeempahla ezifanelekileyo, kwaye ubukroti babo ngokungathandabuzekiyo bavuzwa ngamandla irekhodi Enye yezona zinto zimangalisayo zendalo zibonwa eMhlabeni, ngakumbi kulwandle olunqabileyo lwendawo enomtsalane njengeAntarctica.
Yiyo ke loo nto, phantsi komphezulu ogqunywe ngumkhenkce apho iibhere ezimhlophe, iingonyama zolwandle, oonombombiya kunye nezinye izilwanyana baqhubeka nomsebenzi wabo wemihla ngemihla befuna into yokutya, iijethi zamanzi anomkhenkce zidibana nolwandle, ukuba kubanda kakhulu, kushushu ngokwaneleyo ukuba kubangelwe zizitshingitshane zolwandle, Waziwa ngcono ngegama lebrinicle okanye umnwe wokufa.
Kusekuninzi esinokukufunda kwindalo, kwaye kusenokwenzeka ukuba isinezinto ezingaphezulu kwesinye ezisilindeleyo. Ayaziwa ukuba umntu uzophinda awubone umboniso onje kwakhona, into eyaziwayo kukuba xa esenza, Ndiza kumangaliswa kwakhona.
Ucinga ntoni? Inomdla, akunjalo? I-brinicle iqhubela phambili ngokukhawuleza, irhuqa yonke into eyifumanayo nayo. Ke ukuba ufumana ithuba lokuyibona kufutshane, yonwabele… kodwa umgama, kwimeko apho
KUBALULEKILE UKUYA KWENZEKA KULO MXHOLO SIYABULELA NGAYO YONKE INTO
