Likuphi Sea Beaufort?

A Echibini elithile elincane suburban, yaqanjwa wempi waseBrithani i-Admiral Francis Beaufort - Sea nge izimo ezinzima zezulu esiyingqayizivele lihle ezineqhwa landscape. Yini mayelana kolwandle laziwe? ukuthi kwanele ukufunda?

indawo

Omunye umbuzo wokuqala kuphakama, lapho olwandle Sea Beaufort. Izinkinga impendulo akufanele kwenzeke. Lokhu ulwandle itholakala e-Arctic Ocean. Kule singacabanga eseduzane kwesigubhu kumephu. Kodwa-ke kungcono hhayi ukuqagela, kodwa ngqo ukubuza mayelana ukuphi Sea Beaufort.

Indawo ngqo kungaba azimisele ngendlela elandelayo: Sea Beaufort amanga kancane enyakatho yeNhlonhlo Alaska (indawo ye-US), i-Yukon futhi Northwest Canada. Umngcele osempumalanga egobhoza Canadian Arctic Archipelago. imingcele Western nasempumalanga kuchazwa Sea amaChukchi noLwandle Baffin, ngokulandelana.

Yini mayelana inzwa Sea yaziwa?

Omunye umbuzo othakazelisayo: "Ngubani uphenyo Sea Beaufort?". Ngokusemthethweni, kwatholakala ngo 1826. Incazelo yokuqala olwandle entsha wahlanganyela wamazwe polar John Franklin. Nokho, ngokuphambene isiko, wanikeza Echibini entsha akuyona igama lakhe, futhi uye immortalized igama isikhulu British adumile kanye nososayensi, kamuva owaba undunankulu - F. Beaufort. Sea immortalized igama umuntu wanikezela ukuphila kwakhe Hydrography futhi bahlakulele isikali ekutholeni amandla emoyeni.

John Franklin wenza mikhankaso eziningana Arctic wahlola ugu loLwandle Beaufort. Wabuye, baqhubeka nohambo lwabo ichibi evulekile kubo. Phakathi uhambo lwakhe, wagcina bathole nentaba enkulu yeNyakatho Melika, kokuba sinqume ukuthi kuba lenhlonhlo enyakatho - Butia.

Ngo 1851, lo mkhankaso Beaufort Sea ephethwe ukuwela R. Collison, abavule yezinto eningizimu e ePrince of Wales Strait. Ngawo lowo nyaka eqhweni bomkhankaso Beaufort Sea eba yiqhwa John McClure. Abacwaningi zaphoqeleka ukuba zishiye emikhunjini yabo, kodwa wakwazi ukuhlenga.

Ngo-1905 "uhambo kuya Eskimo" uthethe Canadian Stefansson. Wabuye uphenyo Sea Beaufort.

Usosayensi owaziwa isiRashiya, Doctor of Sciences Geographical, Kochurov Boris Ivanovich, ensimini of ekudwetshweni kwamabalazwe, ekodiagnostiki ekubhekaneni amandla kwemvelo. Ngatadisha izifunda ezehlukene ezifana Altay, Ural, Saha, eMpumalanga Ekude nesifunda Arctic. Phakathi nenkonzo yakhe yokuba ngokwesayensi ukuthi uhlole Kochurov BI noLwandle Beaufort.

izinkomba lokushisa Amanzi

Ososayensi bakholelwa ukuthi izinga lokushisa olwandle Beaufort Kufanele sizimisele ngongqimba ezine:

1. Isendlalelo engenhla ubhekwa m 100 ukujula. Lapha, izinga lokushisa luyehluka in the ububanzi lokususa kusukela -0,4 ° C kuya -1,8 ° ehlobo ubusika.
2. Leli ungqimba Pacific owumthelela ukugeleza ukuthi egcina iBering Strait. ungqimba amanzi yesibili kancane yomusa, kodwa hhayi kakhulu.
3. Isendlalelo esilandelayo efudumele kakhulu. Lakhiwa imisinga Atlantic futhi lokushisa 0 kuya +1 ° C.
4. Isendlalelo phansi kwaba epholile, kodwa nokho kungemina ngakho abandayo, njengoba ngaphezulu, kusukela -0,4 ukuba -0,9 ° C.

Notshwala oLwandle Beaufort aluka kwewashi. Lokhu kubizwa ngokuthi yi kwegazi cyclonic. Ngokusho imithetho efanayo kukhona kwegazi of imisinga ye-Arctic Ocean.

Amapharamitha main

Ake sicabangele izimpendulo zemibuzo nemingcele eziyisisekelo kwesigubhu yangaphakathi ukuthi iqanjwe Francis Beaufort. Ulwandle has a endaweni ingqikithi cishe izinkulungwane 480 sq. Km. I kwesigubhu ukujula avareji -. 1000 m Ngesikhathi iphuzu ejulile - cishe 4700 metres.

usawoti kolwandle akuyona eliphezulu kakhulu. It zokhahlamba kusuka 28 kuya 33 ppm.

River, eBay of Islands

Kukhona ezinye umehluko kusuka kwamanye kwezilwandle we-Arctic Ocean. Kusukela ichibi yethiwa Francis Beaufort ulwandle - yangaphakathi, imifula eminingi iyangena-ke. Lokhu kungenxa kakhulu imisele yamanzi aphakathi nendawo kanye amancane, phakathi okuyinto ebaluleke kunayoyonke - k. MacKenzie. Kusukela phakathi emifuleni angafakwa ohlwini - Anderson, Colville, Sagavanirktok. Ubuningi wamanzi amasha , emafektri inzika bese udala umzimba eziyingqayizivele amanzi kanye nesimo sendawo ngezansi.

I ugu eshalofini ingxenye has eziqhingini eziningi ezincane, ehlanganisa uhlalwane. ukuphakama yabo futhi Ubukhulu njalo siguqula ngaphansi kwengcindezi kweqhwa nemisinga.

Ugu is Kuhlehliswe amatheku eziningi.

impumuzo phansi

Ingxenye enkulu yoLwandle Beaufort isendaweni ungumthombo ongumngcingo eshalofini Continental, ububanzi okuyinto mayelana 50 km. Ukuze eshalofini ukujula imingcele kakhulu sibi kakhulu.

River inzika ukudala obukhulu sedimentary crystalline imali. Kusukela Delta Mackenzie River, isibonelo, dolomite amaminerali awe inhlabathi ngezansi.

Ezansi kolwandle wathola Amasimu uwoyela, okuyizinto Sinesithakazelo esikhulu. Amafutha kanye negesi umcengezi ine indawo engaba izinkulungwane 120. Km. Ukuthuthukiswa Its waqala ngo-1965 futhi kwenziwe kuze kube manje.

Biota

Esikhathini Sea Beaufort, iyikhaya mayelana 70 zezintaka phytoplankton. Kodwa biomass Imininingwane ingenkulu.

Zooplankton wehlukile ngaphezulu, it has 80 zilwane. Ngaphezu kwalokho, inezinhlobo ezingaba ngu-700 zama-ezinamagobolondo futhi mollusk.

Isimo sezulu nokhahlo kakhulu, ukukhanya nokushisa okuncane kakhulu. Sea 11 izinyanga zonyaka imbozwe ungqimba ice. Lokhu kudala izithiyo ezinkulu ukuhlola ekujuleni abakhileyo.

Mayelana ngokwehla kwesibalo sezinhlanzi, kangako. I aphele ezivamile, capelin ne-cod liqhakaze. Ngaphezu kwalokho, sitholakala Kunezinhlobo eziningi cod herring izinhlanzi. Kube ulwe, i-halibut nezimpungushe zasolwandle.

Ezincelisayo Zasolwandle uzizwe emanzini futhi osebeni ngokukhululekile ngempela. Lihlala imikhomo, imikhomo Beluga, izimvu zamanzi kanye walruses. Ngezinye izikhathi kukhona ushaka polar.

Njengoba uLwandle Beaufort kunazo kahle eyaziwa emhlabeni, kunganikeza ososayensi eziningi lezimanga. Into esemqoka - ungadikibali futhi basaqhubeka yini nokutadisha.
