Amundsen Sea: zvemaumbirwo, okunze, miti nemhuka zvakazonaka

Nechokumusoro mvura Pacific Ocean rimwe divi vachiapoteredza kubudikidza mazitombo echando, uye kuno rumwe - kumadokero pamhenderekedzo Antarctica. Pepasi akafuka gungwa yokunyika chando.

Yakabatana nayo inotsvaira kupinda permafrost gabled Cape Dart. Kumabvazuva ndiyo chitsuwa Thurston. Nhangaruvazhe - Meri Berd Land. Sezvaunogona kuona, hatifaniri kuzvinyengera, akapiwa nyaya imwe umo Amundsen Sea muna Pacific Ocean? The Hawaiian Islands vari yakasiyana zvachose chikamu, uyewo zvose akakurumbira nzvimbo dzokugara ose pamhenderekedzo uye dzinoyevedza yezororo.

Geological unhu

Pool iri bordered nevamwe kuchamhembe zvikamu mugungwa, akadai: kuGungwa Bellingshausen uye Ross. nzvimbo Its kunopfuura 98.000 mativi makiromita, avhareji kudzika pfuurei 250 metres. The kuzorodzwa afanane goko, iro rine diki kutsvetera kune huru pamhenderekedzo. On the Nzira kumahombekombe chirefu murwi mazitombo echando.

Chokunze kunogumira Gungwa Amundsen pasherefu muna Pacific Ocean panguva kudzika makubhiti mazana mashanu. Wedzinza mvura kunzvimbo yakatenuka anosiyana, asi Nzvimbo iri mvere, pasina makatsemuka kana matanho. Kureba rinosvika makiromita mana.

Chakarurama Mvura salinity kuchinja nguva dzose. The kunonyanyisa Kuwanda yavaibvisa chloride yakasvika muchando uye ndiyo 33 ppm. Muna July, apo kunyunguduka mazizaya pakati mvura yakachena akazoita zviri NaCl.

Ubanguranyika uye kuwanikidza

Zita dziva akapa akakurumbira akawana uye musayendisiti Roald Amundsen. Norway kwenguva yakareba nguva akadzidza Nordic uye Arctic kumatunhu Antarctica. Uye pano, ari munyika mochari dongo, pamusoro rwendo kokupedzisira.

Ndinoedza kuti pedyo pamahombekombe uye akaita Dzheyms e, uyo akashanyira nzvimbo yechipiri yezana XVIII remakore. Dzepedyo kushambira kuti yakaoma vakakwanisa North America aizi "Palmer" iri gadziriro iri Antarctic rwendo muna 1993.

Nanhasi, mashoko muGungwa Amundsen mashoma uye dzinopesana. Pasinei pokumuka ruzivo kusvika pakatarisana pamahombekombe kunge saka kure hapana yabudirira. Its pool ichaongororwa wakakura zvikuru uye chisingasvikiki.

Nemhenderekedzo chinhu kuunganidza hombe matombo echando. Zvino uye inotsiviwa til precipices. The mvura nzvimbo yeGungwa Amundsen wechisikigo nhovo Antarctic nyika. Ari avepo paumbwe icebergs. Gore negore munharaunda yakabereka 250 cubic makiromita echando.

mamiriro okunze

The dziva iri muumambo Antarctic okunze. Airspace kuumba guru, richibva yakaoma. mvura yaro vane zvikuru kukurukurirana munyanza dzenzvimbo. tembiricha Minimum akacherechedza mumwaka wechirimo. Chinonyanya mondo ndiye July uye August. Kumaodzanyemba chikamu nharaunda panguva ino gore lämpömittari riri pachiyero -18 ° C. Kuchamhembe madonhwe pazasi -28 ° C.

Pamahombekombe kunyange kutonhora. Zvairatidza -50 ° C zviri zvakajairika. Kudziya vaunze latitudes izvi mhepo Nordic. Nyungudika kunoitika munguva yechando mwaka, huchavapo kubva December kusvika February. Panguva ino, tembiricha kunosiyana-siyana iri kuwanda -8 ... -16 ° C. Ocean dzenzvimbo anogona kudziyisa mvura kusvika -1,5 ° C.

wekushandisa mwaka inowira pasi mwedzi izvi. Amundsen gungwa pamusoro rinosanganisira kukukurwa icebergs, pakati iyo yakaumbwa buri chando. All vatatu:

• mumwe ari Bay kuna Russell;
• maviri munzvimbo Thwaites Glacier.

The kunonyanyisa nzvimbo iripo kuti kufamba ngarava iri 55 000 mativi makiromita. Mvura ushamwari 0 ° C. Zvisinei, izvozvo inotonhodza nokukurumidza. Izvi imhaka yokuti kukukurwa chando floes kufukidza nzvimbo akasvinudzwa pamusoro uchanyangadika mvura.

Vagari yokuchamhembe

Chena chando chando mawere yakabudikira pamusoro nechando rakadzikadzika, sokuti upenyu. Asi ichi handizvo. In mvura yeGungwa Amundsen zvinowanikwa nototheniids mhuri hove. Kurarama rwokumusoro PENGUIN uye albatrosses. Spotted zvisimbiso kuti patinodziya mushana, patinoravira ari kupenya kwezuva Cold pemvura echando floes.

Zvinowanikwa izvi nzvimbo, ingwe zvisimbiso, hove huru, zvisimbiso, hove huru uye Dolphins, izvo zvokudya panyama. Pedyo nemhenderekedzo zvinoenderana masere-mita whale.

zvinetso zvemhoteredzo

Over gumi adarika, masayendisiti ari achiyambirawo, achiti pamusoro yokunyanyisa kunyunguduka Antarctic chando. Maererano mashoko awanika kubva satellites, muvhu mutsetse, chinoratidza muganhu pakati pemvura uye nyika chikamu dura aigara ipfupi. Ndizvo sei nhasi anotarisa mufananidzo Sea Amundsen.

makore gumi chete akatora matatu makiromita kupinda Antarctica. Kana tikaenzanisa mwero rutapudzo munharaunda iyi kubvira 1973, nyika zviratidzo, izvozvo yakawedzera kusvika 80%. Yakachinja zvakaipisisa uye inofamba dhayagiramu echando zvavo. Current kuyerwa dzinoratidza kuti munguva gumi mwedzi Nordic Latitude kurasikirwa kusvika bhiriyoni 160 matani ari nechando zvokunwa. Uyu wechitatu kupfuura muna 2011.
