Amundsen Sea: yokwakheka komhlaba, imozulu, izilwanyana

Amanzi yomntla Pacific Ocean kwicala elinye ibiyelwe ezihambayo, yaye kwelinye - elunxwemeni wasentshona Antarctica. Umphezulu lonke wambu ngumkhenkce ndawo yehlabathi.

Kufutshane kuyo, ugxeke kungena permafrost ezinophahla Cape DART. Ukuya wasempumalanga kwisiqithi Thurston. Nal - Meri Berd Land. Njengoko ubona, asifanele siyazikhohlisa, anikwe umba omnye apho Sea Amundsen kwi-Pacific Ocean? ZeHawaii Islands bakwimeko inxalenye eyahlukileyo ngokupheleleyo, ngokunjalo zonke eziya kubakhenkethi oluthandwa elunxwemeni kunye indawo yeholide.

iimpawu zejoloji

Pool into erhangqwe kwezinye iindawo yomntla wolwandle, ezifana: kuLwandle Bellingshausen kunye Ross. indawo yayo ngaphezu 98.000 ezikwere zeekhilomitha, umlinganiselo ubunzulu nje kwama-250 eemitha. Isiqabu kufana iqokobhe, nto leyo iba icala encinane malunga kunxweme nezwe. On kusondela kumhlaba ezinde imfumba ezihambayo.

Ingxenye engaphandle ye kwithala Sea Amundsen kwi-Pacific Ocean ubunzulu seemitha ezimakhulu mahlanu. Selesondele ekuhleni ukuba ithambeka amanzi yahlukile, kodwa zina- agudileyo, ngaphandle iintanda okanye amanyathelo. ubude bayo ifikelela iikhilomitha ezine.

Isalathisi iwunyakamise rhoqo utshintsho etyuwa. Le xi ubuninzi sodium chloride ekufikelelwe ebusika kwaye 33 PPM. NgoJulayi, xa ukunyibilika komkhenkce phakathi kwamanzi acocekileyo kunciphisa umxholo we NaCl.

Exploration nokufumanisa

Igama ichibi wanika discoverer odumileyo-nzulu Roald Amundsen. Norway ixesha elide wafunda Nordic nakwimimandla Arctic Antarctica. Kwaye apha, ezweni entlango Emakhazeni, phezu uhambo lwakhe lokugqibela.

Ndizama ukusondela elunxwemeni kwaye wenze Dzheyms Kuk, abo batyelela indawo kwisiqingatha sesibini senkulungwane XVIII. Novo ukudada ukuba nezwe ilawulwa icebreaker North American "Palmer" kwi-sikhokelo kwiphulo Antarctic ngo-1993.

Nanamhla oku, iinkcukacha kuLwandle Amundsen zinqabile yaye iphikisana. Nangona ukuphuhliswa ubugcisa ukufikelela ibhanki esahlukileyo ziye okwangoku akukho namnye oye waphumelela. pool yayo swimming ithathwa olunzima kakhulu yaye akafikeleleka.

Unxweme yi zemali iibhloko elikhulu ngumkhenkce. Ngoku baze emva koko kufakwe aphakeme ilitye elikhulu. Ummandla amanzi oLwandle Amundsen Uyingweletshetshe yemvelo yeli lizwe Antarctic. Yena abachaphazeleka ngqo kukwenziwa kwazo. Minyaka le mmandla wavelisa 250 kwiikhilomitha cubic ngumkhenkce.

sezulu

Le ichibi ise kummandla imozulu Antarctic. Elibala zakha ubunzima, evela nezwe. amanzi ayo abe unxibelelwano olunzulu kunye yolwandle. Ubuncinane obushushu waphawula ngexesha kwiinyanga zasehlotyeni. Ijeli kakhulu ngoJulayi nango-Agasti. Kumazantsi lommandla ngeli xesha lonyaka ithemometha kukuba kwinqanaba -18 ° C Xa ngamathontsi northern ngezantsi -28 ° C.

Elunxwemeni nokuba esibandayo. Iimpawu -50 ° C ivamile. Botha ungenise ezi ezinezinga umoya yeYurophu. Nobudlelwane kwenzeka ngexesha lasebusika, okuhlala ukususela ngoDisemba ukuya kuFebruwari. Ngeli xesha, ubushushu ziyohluka kwi uluhlu -8 ... -16 ° C. imisinga Ocean nga ukufudumeza amanzi ukuze -1,5 ° C.

ngexesha yokukhangela iwela kule nyanga. Amundsen Umphezulu ulwandle ehlanganiswa kwazo iyalandela, phakathi apho umngxuma yaqalwa ngo ngumkhenkce. Zonke ezintathu zazo:

• elinye Bay of uRussell;
• ezimbini kummandla Thwaites Glacier.

Le ndawo iphezulu efumanekayo intshukumo leenqanawa ngu 55 000 ezikwere zeekhilomitha. Amanzi kuyo othe ukuya ku 0 ° C. Noko ke, ayaphola ngokukhawuleza. Oku kubangelwa yinto yokuba iyalandela ice floes zizobandakanya indawo wavula amanzi anyibilike.

Abemi ngasentla

namawa ice Frosty eveleleyo ngaphezu enzonzobileni engumkhenkce, zibonakala engenabomi. Kodwa akunjalo. Xa amanzi oLwandle Amundsen zifumaneka nototheniids usapho iintlanzi. Ukuphila oonombombiya angasentla iialbatross. amatywina babona ukuba bayive indlela imitha kwelanga kubanda ice floes nonxweme.

Zifumaneka kwezi ndawo, seals ingwe, iminenga, seals, nama dolphins, apho kudla inyama. Kufutshane namanxweme ingqamana whale imitha ezisibhozo-.

iingxaki zokusingqongileyo

Kule minyaka ilishumi idlulileyo, oosonzululwazi isandi alam, esithi malunga kwalowo kakhulu ice Antarctic. Ngokutsho ulwazi efunyenwe kwiisathelayithi, umgca yomhlaba, kuphawula umda phakathi kwamanzi kunye ilizwe inxalenye ichibi kwanciphisa rhoqo. Yiloo ndlela namhlanje ukhangela ifoto kuLwandle Amundsen.

iminyaka elishumi kuphela wathatha kwiikhilomitha mathathu ukuya Antarctica. Xa sithelekisa izinga lokuncitshiswa kule ndawo ukususela 1973, Yayibubungqina, eli nani lenyuswa laya phantse 80%. Buyatshintsha ukuba kubi eshukumayo umzobo omkhenkce baseRoma. imilinganiselo ezenzekayo zibonisa ukuba kwisithuba seenyanga ezilishumi elinesibini yesibanzi Nordic alahlekelwe up iitoni 160 billion of ulwelo wavuma ukuba. Oku yesithathu ngaphezu ngo-2011.
