Amundsen Sea: yokwakheka komhlaba, isimo sezulu, nezilwane

Amanzi enyakatho Pacific Ocean ngakolunye uhlangothi zizungezwé ngu zeqhwa, futhi ngakolunye - ogwini olungasentshonalanga-Antarctica. wonke Kwamanzi embozwe iqhwa wokuziphilisa kwesigubhu.

Eduze kwalo slams zibe eyiqhwa ezinophahla olungunxantathu zisikhumbuza i-Cape Dart. Ukuze impumalanga esiqhingini Thurston. Oyingqopha-mlando - Meri Berd Land. Njengoba ubona, akufanele sizikhohlise, unikezwa udaba eyodwa lapho Sea Amundsen elwandle eliKhulu iPacific? ZaseHawaii basesimweni ingxenye ehluke ngokuphelele, kanye zonke ethandwa izivakashi izindawo ogwini futhi indawo iholide.

izici geological

Pool is izungezwe kwezinye izingxenye enyakatho olwandle, njenge: Sea Bellingshausen kanye Ross. endaweni yayo ingaphezu 98.000 amakhilomitha square, amamitha nje kuka-250 ukujula avareji. Impumuzo ungathi igobolondo, okuyinto has a ukuchema kuzo encane maqondana ogwini ezwekazini. On the izindlela umhlaba ezinde inqwaba kwezinguzunga zeqhwa okwakungokokuqala ngqá.

Emkhawulweni elingaphandle Amundsen Sea eshalofini elwandle eliKhulu iPacific ngesikhathi amamitha angamakhulu amahlanu ukujula. Yehla emthambekeni amanzi kuyahluka, kepha isimo sezwe abushelelezi, ngaphandle imifantu noma izinyathelo. ubude bayo ifinyelela ibanga elingamakhilomitha amane.

Inkomba Amanzi izinguquko usawoti njalo. Ubuningi esiphezulu i-sodium chloride safinyelela ebusika futhi 33 ppm. Ngo-July, lapho ukuncibilika kwezinguzunga zeqhwa okwakungokokuqala ngqá phakathi amanzi ahlanzekile kunciphisa okuqukethwe NaCl.

Ukuhlola nokuthola

Igama ichibi wanika owathola adumile kanye nososayensi uRoald Amundsen. Norway isikhathi eside wafunda Nordic kanye nezifunda Arctic-Antarctica. Futhi lapha, ezweni Ogwadule yezidumbu phezu uhambo lwakhe lokugcina.

Ngizama ukuthola eduze ogwini futhi ukwenze Dzheyms Awe-Kuk, owayevakashela indawo engxenyeni kwekhulu XVIII yesibili. Abaseduze ukubhukuda oya ezwekazini ephethwe North American ophihliza iqhwa "Palmer" kohlaka bomkhankaso Antarctic ngo-1993.

Kuze kube namuhla, ulwazi Sea Amundsen iyivela kancane futhi iphikisana. Naphezu ukuthuthukiswa ubuchwepheshe ukufinyelela ebhange obuhlukile baye kude kangaka asikho esiye saphumelela. ukubhukuda wayo pool kubhekwa kakhulu ongenakusondela kuko nje futhi sinamandla.

Ugu kuyinto ekuqongeleleni amabhlogo yeqhwa emikhulu. Manje bese esikhundleni aphakeme ongagcwali. Le ndawo amanzi oLwandle Amundsen uyisihlangu semvelo sezifunda zaleli zwe-Antarctic. Ubizwa abahileleke ngokuqondile kumiswa zeqhwa. Minyaka yonke ndawo yayikhiqiza 250 cubic amakhilomitha ice.

sezulu

Ichibi itholakala endaweni sezulu Antarctic. Wezasemoyeni yakha mass, ivela ezwekazini. Emifuleni yakhona une-zokuxhumana okukhulu nge imisinga ulwandle. lokushisa Ubuncane waphawula phakathi nezinyanga zasehlobo. Jelly kakhulu kuyinto July no-August. Engxenyeni eseningizimu yale ndawo ngalesi sikhathi sonyaka thermometer kuyinto ezingeni 18 ° C. Ngo amathonsi enyakatho ngezansi -28 ° C.

On ogwini ngisho ngaphansi kwezingaqhwa. Izinkomba -50 ° C akukhona okungavamile ukuba likhithike. Ukufudumala yokuletha lezi zindawo umoya Nordic. Ukuncibilika kwenzeka ngenkathi ebusika, okuyinto Uthatha kusukela ngoDecember kuya kuFebruary. Ngalesi sikhathi, izinga lokushisa siyahlukahluka uhla -8 ... -16 ° C. Yolwandle ungakwazi ukufudumeza amanzi ukuze -1,5 ° C.

navigation isizini ewela lezi izinyanga. Amundsen ulwandle ebusweni imbozwe ukukhukhuleka zeqhwa, phakathi lapho imbobo kwakheka ice. Njengamanje bobathathu:

• omunye eBay of Russell;
• ezimbili endaweni Thwaites Glacier.

Le ndawo esiphezulu etholakalayo ukuhamba ngemikhumbi 55 000 amakhilomitha square. Amanzi kulo ukuxoxa nabo 0 ° C. Nokho, ayaphola ngokushesha. Lokhu kungenxa yokuthi i-ukukhukhuleka zeqhwa ukumboza indawo wavula yamanzi ncibilika.

Izakhamuzi enyakatho

Nesithwathwa ice amawa aphumele ngaphezu kwalasha eqandisiwe, kubonakale ezingaphili. Kodwa lokhu akulona icala. Esikhathini amanzi oLwandle Amundsen atholakala nototheniids izinhlanzi umndeni. Ukuhlala penguins enyakatho futhi albatross. seal Spotted ukuthi ezikudingayo imisebe ilanga ku umkhuhlane sogu lolwandle zeqhwa.

Atholakala kulezi zindawo, ingwe zamanzi, imikhomo, izimvu zamanzi, imikhomo namahlengethwa, okuyinto zidla inyama. Esiseduzane ugu esifanelana imitha ayisishiyagalombili-whale.

izinkinga zemvelo

Eshumini leminyaka elidlule, ososayensi okuzwakalisa inhlabamkhosi, bathini mayelana ukuncibilika okukhulu ice-Antarctic. Ngokusho batshele abanye izinto ezishiwo iziphuphutheki, phansi line, kuphawula umngcele phakathi kwamanzi futhi ingxenye ezweni kwesigubhu encishisiwe njalo. Yileyo indlela namuhla ukubuka lesi sithombe Amundsen Sea.

iminyaka eyishumi kuphela wathatha amakhilomitha amathathu ku-Antarctica. Uma siqhathanisa izinga lokwehliswa kule ndawo kusukela ngo-1973, izimpawu, lenyuka cishe ngo-80%. It ukushintshwa umdwebo sibi futhi motion ice uquqaba. izilinganiso ezenzeka manje zibonisa ukuthi isikhathi esiyizinyanga eziyishumi nambili latitude Nordic ulahlekelwe izimpahla ezingamathani angu-160 billion ketshezi eqandisiwe. Lena yesithathu ngaphezu ngo-2011.
