Amazinga kanye usawoti yoLwandle uBarents. Uyini usawoti yoLwandle uBarents e ppm

I uBarents Sea - ulwandle, esisogwini emaphethelweni e-Arctic Ocean. Okuningi ngokunembile, kakusekho kwe-Arctic Circle, phakathi eziqhingini Svalbard, Franz Josef Land, Vaigach nasogwini yeYurophu. amanzi uBarents Sea ugeza ogwini Norway, kodwa ngaphezu kwakho konke - eRussia. Kuze kube sekupheleni kule ndawo engakaze wafunda. Abaningi alazi ukuthi usawoti yoLwandle uBarents, futhi uyini lokushisa amanzi alo. Nokho, lokhu kungenziwa alungise.

Amachibi ahambayo

I usawoti kanye lokushisa yoLwandle uBarents kukhona kuncike ezicini eziningi. Phela, amanzi ihlinzekwa lapha hhayi kuphela ngenxa emifuleni, kodwa futhi usuke e-Atlantic. Konke lokhu kuba nethonya le usawoti kanye lokushisa. Kumele sicacise ukuthi ukugeleza komfula, unikezwa ivolumu kanye endaweni kolwandle, kulesi simo uphansi. Phakathi nonyaka, nakhu kufika ekubonakaleni cubic amakhilomitha angaba 163 nomthombo wamanzi aqabulayo. emifuleni Iningi ageleze ngokunembile engxenyeni eseningizimu-yolwandle uBarents. Lapha kwasho Umthambo ngobukhulu. Ukwahlulela ngokubukeka izinkomba evamile ukutholakala kwamanzi, Pechora phinda echibini mayelana 130 cubic metres yamanzi. Lokhu kusho ukuthi bangaba ngu-70% wezindleko emfuleni ukugeleza phakathi nonyaka. Kule ndawo, kolwandle agelezela amadamu amaningi amancane.

Kuyaphawuleka ukuthi ogwini yeNhlonhlo Kola futhi ugu lweNyakatho Norway akhawunti ye-% 10 kuphela emfuleni flow. Phela, lapha iwe ukusakaza ikakhulukazi ezincane entabeni. Izinga eliphezulu kakhulu amanzi emifula yezwekazi ebonwe entwasahlobo, futhi okungenani - ebusika ekwindla. Kodwa kuthinta usawoti yoLwandle uBarents. Kuyaphawuleka kuthinta emfuleni ukugeleza kuphela izimo kwamanzi yaseningizimu-esempumalanga. Le ndawo kolwandle engajulile kakhulu, futhi uvame ukubizwa ngokuthi Caves pool.

ulwandle okuseduze

I usawoti yoLwandle uBarents, kanye nezinga lokushisa elizosetshenziswa amanzi awo ungaxhomeki kuphela fresh amanzi emifula. On lezi zibalo ithonywe ngokungadingekile eminye zici. Ungakhohlwa mayelana exchange amanzi nge ezilwandle, elise kamakhelwane. Yiqiniso, kufanele inake izici zabo ethize. Kakhulu e Sea uBarents ithola amanzi Atlantic efudumele. kwatheleka Lonyaka cishe 74 izinkulungwane amakhilomitha square.

Amanzi aphuma kwezilwandle eduze alethwe Sea uBarents kusuka 177 kuya 1012 kcal ukushisa. Kuleli nani is amuncwa-12% kuphela. Ezinye izindaba zika-ukushisa kasisekho Sea uBarents. Ngokwemvelo, amanzi awekho njengoba abandayo. Kuyaphawuleka: Sea uBarents - ulwandle efudumele phakathi kwalabo ayingxenye-Arctic Ocean. Ezinye izindawo nje, hhayi kwi freezer. lokushisa Water ezisukela emikhawulweni European ziphethe 75 ° enyakatho nenkabazwe - ngokuqhubekayo ngenhla zero.

Isakhiwo amanzi

Ukuze sithole lokho usawoti oLwandle uBarents, kubalulekile ukuba acabangisise isakhiwo amanzi alo. Okwamanje kukhona 4 isisindo eziyisisekelo:

1. Atlantic kwabo amanzi - ukuthi iningi amanzi ebusweni kuya phansi. Eza ikakhulukazi esivela enyakatho-mpumalanga, enyakatho-ntshonalanga ye-Arctic Basin. Lezi uquqaba zifudumala futhi elungisiwe.
2. Arctic - isisindo ukuthi uhambe olwandle kusukela enyakatho ngesimo samanje ebusweni. Lezi ziye zanciphisa amanzi usawoti, futhi izinga lokushisa ezimbi.
3. emanzini angasogwini. Lezi uquqaba zingena olwandle zivela emifula yezwekazi kusukela White Sea, kanye wamanje osogwini ukusuka oLwandle Norwegian nasogwini Norway. Ngesikhathi sasehlobo la manzi abe okusezingeni eliphezulu lokushisa ukusebenza usawoti ezincane. Ebusika, izici elisogwini uquqaba zifana kakhulu uquqaba Arctic.
4. akha ingxenye enkulu yomsebenzi okuyinto olwandle ngenxa ekuguquleni ubungako Atlantic nethonya izimo zendawo - uBarents Sea amanzi. Basuke izimpawu usawoti okusezingeni eliphezulu futhi lokushisa ongaphakeme. Ebusika, enyakatho-esempumalanga ligcwele ngokuphelele emanzini lendawo uBarents Sea, eningizimu-ntshonalanga okuyingxenye - Atlantic. uquqaba Arctic bengekho nhlobo, futhi ugu waphawula kuphela imisinga ebusweni. Kuyaphawuleka ukuthi usawoti uBarents Sea injalo ingashintshile. Phela, uquqaba ezingefani ngokushesha okuxubile.

I uBarents Sea: usawoti

ULwandle uBarents kahle exhunyiwe olwandle. Kulokhu ezwekazini osenyameni angenasawoti incane. Ngenxa yalesi izinkomba usawoti kukhona cishe enjalo futhi musa zehluke usawoti isilinganiso olwandle. Kuyaphawuleka ukuthi izinguquko ungaxhomeki kuphela zonyaka kodwa futhi kusukela ezifundeni. Ngokwesibonelo, engxenyeni eseningizimu-ntshonalanga waphawula usawoti esiphezulu yoLwandle uBarents. Lapha, bangamaphesenti 35 ‰. Kuyinto endaweni wokuxovela North Cape. Kukhona okunosawoti kwabo amanzi Atlantic futhi ungalokothi ice.

Engxenyeni eseningizimu nasenyakatho ye ukusebenza ukwehla ukuze 34,5 ‰. Endaweni wabonisa ukuncibilika iqhwa. Esikhathini mpumalanga kwabo amanzi ahlanzekile nakakhulu. Kule ndawo yoLwandle uBarents le usawoti e izingxenye ngamunye million cishe 32-33 ‰. Kukhona ephawulwe emfuleni ukugeleza elikhulu amanzi ahlanzekile. Kule ndawo kukhona ukuncibilika iqhwa.

I usawoti kanye izingqimba

Ushintsho E-usawoti kukholamu amanzi luncike nemingenela Atlantic kwabo amanzi, umfula indle, kanye kusuka phansi impumuzo. Ngezinye kwamanzi, zingamelela kusuka 34 ‰ noma ngaphezulu, futhi ezansi - kuze kufinyelele 35.2 ‰. Ngo izinguquko ezincane ngaphezulu kubalwe phakathi ngwenya ngenhla ahlangabezana thwi.

Kuyaphawuleka ukuthi cishe akukho ushintsho ngesikhathi izinkomba inkathi usawoti. Izinguquko ebuthaka kakhulu. Isendlalelo amaqabunga eliphuphile ngaphezulu ehlobo. I ukwanda okukhulu kwezincwadi usawoti kanye nokujula siyenzeka kusuka ekujuleni 25-30 amamitha. Ebusika, gxuma ezifanayo cishe eshelelayo. Engxenyeni eseningizimu-mpumalanga yesifundazwe izinguquko kumakwe kahle usawoti indices ukujula. Kuyaphawuleka ukuthi kwezinye izindawo umehluko ingaba ppm ambalwa.

Ebusika, le waphawula ukuqondanisa izinkomba bacishe bayifunda yonke ukushuba Sea uBarents. Entwasahlobo, ungqimba ebusweni iba flat. Ehlobo yale nqubo sigcizelelwa ngenxa ice encibilika. Yingakho phakathi khathizwe ka 10-25 kwakukhona gxuma elibukhali usawoti.

I kwabantu of amanzi

Ngaphezu kwalokho, ungakhohlwa mayelana nezinye izinto. Ngokwesibonelo, endaweni North Sea ebusika kwabo amanzi kukhona luthe ukuqina, futhi central - ehlobo. Kulokhu, izizathu lesi simanga awafani. Enyakatho, kwenzeka ngenxa irisidi ezingabangela ukungatholi amanzi ahlanzekile, futhi eningizimu - ngenxa yokufudumala kwembulunga.

I usawoti we uBarents Sea ezithile zonyaka

Ngo Inkomba ebusika ngaphesheya endaweni ulwandle kuqhathaniswa eliphezulu futhi 35 ‰. Kunabo bonke engxenyeni eseningizimu-mpumalanga - kuze kufinyelele 33 ‰. Lokhu kungenxa inflow enkulu uquqaba Atlantic, nokuncipha emifula yezwekazi kanye ukubunjwa okukhulu ice. Spring, amazinga okuhlola alokhu usawoti okusezingeni eliphezulu. Okuwukuphela isiqeshana ewumngcingo ugu ku Kanin-Kolguev esifundeni kanye Murmansk ogwini. Lapha, i-usawoti incipha.

Ehlobo kukhona ukuthutheleka amanzi quba Atlantic Ocean, encibilika ice nokusatshalaliswa kwamanzi emfuleni. Ngenxa yalokhu nani kakhulu ziyancipha. Engxenyeni eseningizimu-mpumalanga yesifundazwe uphawu angawa 25 ‰, futhi eningizimu-ntshonalanga - ukuze 34,5 ‰. Ekwindla ka indices futhi egcinwe encishisiwe. Nokho, ngenxa yokuthi amanzi ayegeleza yezwekazi kancane kancane kubambezela, le usawoti yoLwandle uBarents kuphesenteji iyakhula. Ngaphezu kwalokho, ukwakheka okusheshayo ice iqala kule nkathi. Kancane kancane ukukala usawoti ifinyelela izinga ebusika.

Ekupheleni

Manje ngoba sewuyazi ukuthi uyini usawoti yoLwandle uBarents nokuthi kuthinta. Naphezu iyehla iyenyuka ezinjalo, iqukethe mayelana 110 nezinhlobo zezinhlanzi ezingu. Lesitshalo ukwehluka incipha usuke entshonalanga uye empumalanga. Lokhu lihlotshaniswa nokuncipha lokushisa lamanzi futhi emoyeni, futhi iqhwa imodi. Kuyaphawuleka ukuthi uBarents Sea cod onika emadolobheni amaningi, Bychkova nezinhlobo flatfish. Okwamanje, lapho limbiwa haddock, capelin, inhlanzi, i-halibut, cod, eyikati, cod elimboze izindawo ezibandayo kanye redfish.
