Duniduna waxay organic ah ee Ocean Arctic ah (kooban)

noolaha ku nool Arctic ah, ayaa ku dhibtooneysa. cimilada aad u qabow, baraf weligeed ah, baraf cad iyo habeen horjeeda 5-6 bilood sano - qaababka ugu muhiimsan ee xaaladaha adag ee gobolka mugdiga iyo sub-Arctic. Duniduna waxay organic ah ee Ocean Arctic la sameeyay ee ka mid ah xaaladaha adag. Siyaabo badan ku-qaboobaha ah la lafaguro ka soo jeeda gobollada qoraxda iyo kulaylaha Badweynta Adduunka (IO) oo kala duwan. Muujiyo oo si kooban sharaxaad qaababka kuwan.

xaaladaha dabiiciga adag ee Arctic ah

Snow iyo baraf ka adkaan kor Circle Arctic ah, dunida organic islana kuwaas Tilmaamo dabiiciga ah. Qayb ka mid muhiim ah ee gobolka cidhifka woqooyi ee caalamka degan meelaha biyo qabow, ku xidhan barafka. In dalalka kala duwan ee koorsada oo ka mid ah magacyada meesha soo socda: ka Arctic, Polar ama badweynta Arctic ah. Summer ee latitudes sare gaaban oo qabow, jiilaalka waa muddo dheer oo aad u daran. Roobab dhaco sida barafka cad, tiradiisa yar yahay - oo kaliya oo ku saabsan 200 ml.

Duniduna waxay organic ah ee Ocean Arctic ah - waa xayawaankii degganu hooseysa, xeebaha iyo jasiiradaha badan oo ka mid ah badaha Arctic ah. xoolo badan iyo qaar ka mid ah dhirta yar oo ku habboon kul hoose on barafka iyo barafka. kuwaas oo deggan Hardy dalka oo aad u daran Sidee tahay? Shimbiraha iyo nuujiya ku nool latitudes sare, sida caadiga ah cad.

kala duwanaanta nolosha ugu hooseysa Dhammaan muujinaysaa benthos ah. algae Tani, mollusks, coelenterates, ku lifaaqan substrate reer shelf iyo jiirada qaaradda, gurguurta crustaceans. Algae heysatay kelp iyo fucus. eelgrass dhirta ubax waxaa laga helay badda Cad. xayawaanka Benthic waxaa intooda badan la xiriira xawayaanka (gooryaan, buushka, badda anemones iyo xiddigaha, clams, u haysteen doontooda). Waxay u adkeysan karaan maraan qabow iyo moolka dheer mugdiga ah ee badda.

Oo ka mid ah ku dhawaad 200 nooc oo phytoplankton, inta badan la xiriira diatoms.
flora Finensej badda xeebteeda taal oo archipelagos badan oo wakiil gymnosperms, ubax dhirta iyo lichens. silsilado Cuntada waxaa ka mid ah zooplankton, xawayaanka badda, kalluunka, shimbiraha, nuujiya. Labada kooxood ee ugu danbeysay ee ay degi doonaan xeebaha iyo jasiiradaha, cunto uga helaan marar badan laga helay biyaha waa ka xor baraf. Waayo, dunida ka mid ah shimbiraha ee Arctic ah waxa lagu gartaa noocyada qaninimo, iyo "rookeries" buuq kala duwan dunida organic ah ee Ocean Arctic ah.

List of xoolaha ee Arctic ah

Xawayaanka: cyan xayawaan badeed, Ophiuroidea "Gorgon madaxa", clams iyo crustaceans.
Greenland Shark taagan size badan oo kalluunka ka mid ah. wakiillo kale oo ka dubato kalluunka, salmon, cunna, kalluun, kaluun, flatfish (oo ay ku jiraan Paltusova). Shimbiraha: ptarmigan, guillemot, iyo guumaysta baraf, terns, gorgor bidaarta.

nuujiya:

• nibiriyada badda waayihiisa (nibiriga Beluga, narwhal);
• shaabadood (kataarad, xariijimo, seal ringed, shaabadood Aloosan);
• walruses
• caddaan ama orso oo kala horjeeda,
• Deerada (caribou)
• in Yeeyi Cunto Arctic;
• dibi Miski;
• bakaylaha cidhifka woqooyi;
• lemming.

Qalabka of dhirta iyo xoolaha ee Arctic ah

Duniduna waxay organic ah ee Ocean Arctic on noocyo kala duwan oo phytoplankton dhow dhow meelaha waqooyi ee Atlantic iyo Pacific. Waxa xiiso leh, qaar ka mid ah algae cqaadir hayn awood u leh inay photosynthesize xitaa on barafka. Sidaas darteed, dusha cad waxaa lagu daboolayaa filimka meelo godgodan oo-brown, iyo barafka dhalaalayaa dhakhso. biyo qabow dhexdhexaad ah hodan ku oxygen iyo nitrogen kala diri, marka hoos lakabka Jibriilba u qoto dheer nafaqeeyayaalka yar lagama maarmaan sare culus phytoplankton. Astaamahani waa la abuuro shuruudo wanaagsan ee horumarka degdeg ah noolaha cqaadir.

nooc ka mid ah astaanta, astaanta oo aqoonsan dunida organic ah ee Ocean Arctic ah - orsada kala horjeeda. Tani waa mid ka mid ah bahal jidhadhka dhulka ugu weyn; jirka oo lab ah Adult gaaro dherer ah 2-3 mitir. Waxaa cunto siiya inta badan shaabadood, kalluunka. White Bear Arctic iyo xayawaanka kale awood u leeyihiin in ay yareeyaan shiid marka heerkulku hooseeyo. Waxay si tartiib ah u kora, laakiin gaari kara xajmiga weyn iyo dadka waayeelka ah. Tusaale ahaan, urchin badda kulaylaha dhif ku nool yahay 10 sano, a noocyada kala horjeeda jira in ka badan 60 sano.

cimilada wax yar ka jilicsanaayeen badaha ee qaybta Yurub ee Arctic ah, sidaas oo kale ayaa dhirta iyo ugaarta waa doonee. The ugu dadku ku badan yahay shelf ah gacmeed qaaradda. Laakiin on dhirta oo dhan iyo duniduba ay wada organic waa saboolka ah ee noocyada. sababaha ugu weyn ee ka mid ah - xaaladaha cimilada adag, la'aanta iftiinka qoraxda iyo kulayl doog, la'aanta ah ee cuntada xoolaha.

Kooban Ocean Arctic

Qaybta ugu hooseeya iyo qabow ee badweynta dunida degan% ka mid ah meelaha ay total oo kaliya 4. Ocean Arctic waxay ku taalaa ku dhowaad ee xarunta of Arctic ah. Meesha soohdintu waa line shuruudaysan - Arctic Circle (66 ° barbar w ..). Arctic waxaa ka mid ma aha oo kaliya meelaha biyaha, laakiin sidoo kale jasiiradda, xeebta qaaradood. Webiyaasha Ocean Arctic ah - mid ka mid ah ugu full-dal oo adduunka ah. Qulquli gelin badaha Arctic: ku Yenisey, Lena, OB, Pechora, Yana, Kolyma, Indigirka. Cidhiidhi Bering Strait kala sooco biyaha horjeeda ee Pacific. oo soohdintu waxay la Atlantic waxay kuorodaa dhex Peninsula Scandinavian iyo xagga koonfureed oo reer Greenland. On dhulka of Arctic waa baallaha waqooyiga juqraafi.
