Izintaba-mlilo-Antarctica - izimfihlo yokuzamazama

Antarctica - nezwekazi okuyimfihlakalo penguin zingwadule ezineqhwa ice okuphakade, zinyanga kuvulwa ezwekazini namuhla kahle eyaziwa nokufihla izimfihlo unrevealed. Izintaba-mlilo-Antarctica - omunye walabo izimfihlakalo angekho ezisheshayo ukuvula.

Hidden ice ukujiya

Kuyasebenza futhi yokuqothulwa, umhlaba kanye kwamanzi - Namuhla nezwekazi mlilo Antarctica linohlu engaba ngu-35 ezweni, futhi okungenani 18 wabo - esebenza. Elokugcina latholakala 2008, lifihliwe ngaphansi eqhweni futhi iseduze eGulf of Pine Island Hudson Mountains. Kwatholakala e ephenya ngokuthengwa ice okuvela emoyeni, futhi bangaki kubo okwamanje wathola?

Eyokuqala, kodwa hhayi zokugcina

Umbuzo: "Awakho izintaba-mlilo e-Antarctica?" Walahlekelwa ukuhlobana e ezikude 1841, lapho uhambo iJames Ross wabona izintabamlilo ezimbili - ithule oyibamba Erebus futhi Terror (okuthiwa ngoba imikhumbi uhambo). Kusukela ngaleso sikhathi yaqala isifundo mlilo futhi izinto ezintsha. Ngakho, ngo-2010, kuye kwaba nemibiko ku kuvulwa uchungechunge 12 undersea izintaba-mlilo i-Antarctica. Ukusebenzisa sonar Kuye kwatholakala ukuthi ezinye ukuphakama ifinyelela angu-3. Seven kulo bayizinkulungwane iyasebenza, futhi amanzi mlilo ndawo ububanzi kufika ku 5 amakhilomitha.

Erebus intabamlilo

Southern kunazo zonke izintaba-mlilo eziqhumayo emhlabeni - Erebus - has a ukuphakama cishe 4000 amamitha ngaphezu kolwandle futhi emgodini ububanzi 805 amamitha ekujuleni 274 amamitha. Lena ngenye yama-mlilo ezintathu le planethi, okuyinto ekujuleni ichibi wentaba-mlilo ongashi lava. Yilokho unikeza Erebus kukhanya eyinqaba eyaba beacon kuwo wonke amatilosi Sea Ross. Owokugcina kule minyaka eyikhulu 8 kuqhuma ezinkulu kwaba ngo-1972, lapho lava ukhiphe a ukuphakama esinezitezi eziyisishiyagalombili.

Conquest of Erebus - iyindaba udumo

Ukuze abacwaningi e-Antarctica ukugibela kule intabamlilo esiyingozi sekube ngasuthi Yazi. Okokuqala walinqoba ngo-1908, iqembu osolwazi bomkhankaso ka-Ernest Shackleton, owayeneminyaka engu-50 ubudala. Kuyinto lezi abacwaningi kuqala wabona echibini lava emgodini wentaba.

Izazi zesayensi yokwakheka komhlaba kusukela New Zealand ngo-1974, bamisa e komgodi wentaba-mlilo, kodwa umsebenzi lo intabamlilo awubavumelanga ukuhlola wentaba kwangaphakathi. Nakuba indlela eya intabamlilo zivimba iphakama ezineqhwa amaningi ngonyaka zithuthelekela ke, abacwaningi, kakhulu.

intabamlilo Ukukhohliswa

phakathi Shetlanskih lingasempumalanga yalesi siqhingi, 850 amakhilomitha eningizimu-mpumalanga ye-eCape Horn iyona umsunguli nesenzakalo Bay Port Foster. It is lokhu mlilo kubhekwa obhekene ukuqhuma ngobukhulu aziwayo. Intaba-mlilo wavula ngo 1820, kusho uCaptain Uilyam Smit, futhi ngo-1960 kwabonakala ilunga UK Station, Chile futhi Argentina. Esikhathini esiyiminyaka 1967-1969 sika, ngenxa nokuqhuma eziningana, Chile nase-UK iziteshi ezibhujisiwe. i-Argentina, lapho ngo-2000 wajoyina abaseSpain kuphela.

Ukukhohlisa ongaqondakali

Lena ezingavamile "ice mlilo", engaphansi ukushuba yeqhwa amamitha angu-100. Thanda ihamba kancane futhi kuziwa kwamanzi nenani elikhulu udoti. Mlilo namuhla akuyona ungaqiniseki ngokuphelele umsuka intabamlilo - ukuthi lokhu intabamlilo nemifantu (kwehlukana uqweqwe), kungakhathaliseki ukuthi kwakhiwa it is by subduction (owodwa dive uqweqwe ngaphansi komunye) izingqimba zomhlaba.

Mount Sidley

Land Meri Berd wesifunda yakhiwa wentaba-mlilo entabeni yokhalo kwiBhodi (Executive Committee Range). Ukuphakama kweNtaba Sidley ecishe ibe yizinkulungwane 4.3 amamitha, unyawo - ayizinkulungwane 2.5 amamitha. Omunye ohlangothini lwentaba yakha mgodi wentaba-mlilo eziqhuma nge ububanzi 5 amakhilomitha. I ukushuba we enamathela ice ifinyelela 2 amakhilomitha futhi uma iqhwa liyancibilika, kubonakala lapha ngesimo Japan leziqhingi of mlilo yesibili.

Izintaba-mlilo-Antarctica kanye nekusasa iplanethi

Ngokusho Nature Geoscience, mlilo kuthinta izinga leqhwa ukuncibilika. Heat ephuma Antarctica izintabamlilo edabula ungqimba lomhlaba, kubangela ukuntengantenga yezwe ice igobolondo. Ososayensi baye eyenziwe ibalazwe iplanethi emva ukuncibilika esivezwa ice-Antarctic. Futhi akudingeki engxenyeni enkulu yeNyakatho Melika kanye ezindaweni ezisogwini of India. Ngokuphelele kwamanzi eLondon Venice, Netherlands naseDenmark. Emazweni ukuthi uzohlupheka, akukho Russian.

Antarctic fantasy

Ngo-2017, abezindaba babika imisebenzi NASA emgodini wentaba intaba-mlilo Mount Erebus kusesho portal kwamanye imihlaba noma iminonjana njengabafokazi. Manje wonke umuntu uyazi ukuthi le ntaba-mlilo itholakala e-Antarctica.

A elikhulu incwadi imitha ezimbili "M" kwenye iziqhingi umsebenzi uye kuyisikhathi eside kungaziwa. Kodwa kwathi ngale ndlela umcwaningi Polish immortalized igama lady yenhliziyo yakhe uMagda. Nokho, impahla esikhethiwe ezithakazelisayo - kuba indle ka penguins.

Amabili iziqongo idwala emnyango ULemaire Channel okuthiwa ngempela ehlukile - "Boob Una." Njengengxenye bomkhankaso British ngempela kwaba intombazane Una. Ngokuthakazelisayo, kusukela ezinye izintaba-mlilo manje angenamagama.

Ngo-Antarctica, eziningi amachibi subglacial ngamanzi ahlanzekile. Ngokokunye ukulinganisela, kunezinguqulo ezingaba ngu-140. Kodwa enkulu - East. ububanzi amakhilomitha 50 nobude - 250.

Kodwa kusukela Taylor Glacier ageleza Igazi Falls. Lesi simo esiyingqayizivele sibangelwa kungenxa yomsebenzi webhaktheriya echibini subglacial. Bona secrete yensimbi bivalent, okuyinto Amabala amanzi emoyeni ngombala eliyingozi.

Ukuze ukuphoxeka eziningi, azikho amabhere e-Antarctica. Zaziziningi izilwane lapha ulwandle kuphela - killer ushaka kodwa iqhwa. Yingakho penguins ku mhlaba ngokugqamile.

Ngo-Antarctica, zikhona 5 iziteshi polar Russian. Umhlangano omkhulu kunayo yonke - "East" - kuyinto endaweni geodesic-South Pole.
