Iqondo lobushushu kunye etyuwa oLwandle Barents. Yintoni na ubutyuwa oLwandle Barents kwi-PPM

I-Sea Barents - ulwandle, kubekwe phezu elunxwemeni Arctic Ocean. Okunye ngqo, oko elingaphonoshono Arctic Circle, phakathi kwiziqithi Svalbard, Franz Josef loMhlaba, Vaigach kunye lase Europe. amanzi oLwandle Barents ahlambe lwaseYurophu eNorway, kodwa okona kubalulekileyo - Russia. De kube sekupheleni kwale ndawo ukuba kufundwe. Abaninzi Andazi nokuba yintoni na etyuwa koLwandle Barents, yaye yintoni na ke ubushushu bamanzi ayo. Kaloku, oku zinokulungiswa ngayo ngaphandle.

yamanzi namanzi ahambayo

Le etyuwa kunye lobushushu kuLwandle Barents axhomekeke kwizinto ezininzi. Ngapha koko, amanzi anikwa apha hayi nje kuphela ngenxa yokhuphiswano emilanjeni, kodwa ukusuka Atlantic. Konke oku onesiphumo kwi etyuwa neqondo lobushushu. Kufuneka sicacise ukuba flow umlambo, banikwa umthamo kunye indawo yolwandle, kule meko iphantsi. Kulo nyaka, apha uza malunga 163 neekhilomitha cubic amanzi acocekileyo. imilambo Inkoliso kungena kanye emzantsi-mpuma inxalenye kuLwandle Barents. Apha kwaphawula Umthambo. Xa izalathisi ukunyamezela nokufumaneka kwamanzi, Pechora icwangcisa kwichibi malunga 130 cubic metres yamanzi. Oku kubonisa malunga ne-70% ye-flow lomlambo iyonke kulo nyaka. Kule ndawo, ulwandle eliya amadama ezininzi ezincinane.

Kubalulekile ukuphawula ukuba kunxweme ye Kola Peninsula kunye unxweme akhawunti eNorway% 10 kuphela lokuhamba lomlambo. Ngapha koko, apha kuwa imilambo becala ezincinane entabeni. Izinga eliphezulu abalekayo lizwekazi waphawula entwasahlobo, kwaye ubuncinane - ebusika kunye ekwindla. Kodwa kuchaphazela etyuwa koLwandle Barents. Ngokuphawulekayo kuchaphazela flow kuphela kwiimeko ezinamanzi ze-inxalenye kumzantsi-mpuma umlambo. Lo mmandla ulwandle kakhulu nzulu, kwaye udla ngokubizwa ngokuba Caves echibini.

ulwandle ezikufutshane

Le etyuwa koLwandle Barents, kwakunye amaqondo obushushu amanzi alo azixhomekekanga kuphela amanzi amanzi amtyuba namnandi. Kula manani kuchatshazelwa ezinye izinto. Musa ukulibala malunga exchange amanzi aselwandle, ibekwe emnyango elandelayo. Kakade ke, kufuneka ithathele ingqalelo iimpawu zabo ezithile. Uninzi kuLwandle Barents ifumana amanzi efudumeleyo Atlantic. wokufika yonyaka nama-74 amawaka ezikwere zeekhilomitha.

Amanzi ngabeelwandle nawayenxuse bazisa kuLwandle Barents ukusuka 177 ukuya 1012 kcal ubushushu. Kule mali ifunxwe yi%-12 kuphela. Ezinye ubushushu isetyenziswa kuLwandle Barents. Ngokuqhelekileyo, akunguye amanzi abandayo. Kubalulekile ukuphawula: uLwandle Barents - lo ulwandle eshushu phakathi kwabo ukuba yinxalenye ye-Arctic Ocean. Ezinye iindawo nje hayi ngumkhenkce. lobushushu Amanzi ezisukela mida aseYurophu kwaye ugcina 75 ° inkululeko kumntla - ngokuqhubekekayo ngentla zero.

Ubume amanzi

Ukuze ubone ukuba yintoni na etyuwa kuLwandle Barents, kuyimfuneko ukuba siqwalasele ngenyameko ubume amanzi ayo. Okwangoku ezi 4 ubunzima ezisisiseko:

1. kwabo amanzi Atlantic - uninzi amanzi avela kumphezulu ukuya ezantsi. Baya kuza becala evela mpuma, kumntla ntshona i-Arctic Basin. Ezi izihlwele ishushu kwaye okunencasa.
2. amanzi Arctic - ubunzima ukuba baye elwandle ukusuka emantla ngokohlobo kumphezulu yangoku. Ezi ziye zancitshiswa etyuwa amanzi, kunye lobushushu ezimbi.
3. amanzi onxweme. Ezi yenkitha ulwandle kwamanzi lizwekazi ukusuka kuLwandle White, ngokunjalo kunye umsinga wonxweme kuLwandle Norwegian elunxwemeni yaseNorway. Ngexesha ehlotyeni ezi amanzi yokusebenza lobushushu eliphezulu kunye etyuwa ezingephi. Ebusika, iimpawu eselunxwemeni yenkitha ezifanayo kakhulu kwinginginya Arctic.
4. amanzi oLwandle Barents - a isambuku leyo luqokelelane elwandle ngenxa inguqu kwiinginginya Atlantic kunye nempembelelo neemeko zendawo. Bona ebonakala etyuwa eliphezulu lobushushu eliphantsi. Ebusika, inxalenye kumntla-mpuma izaliswe ngokupheleleyo emanzini basekuhlaleni kuLwandle Barents, inxalenye kumzantsi-ntshona - i-Atlantic. izihlwele Arctic abangekhoyo ngokupheleleyo, yaye elunxwemeni waphawula kuphela imisinga kumphezulu. Kubalulekile ukuphawula ukuba etyuwa Sea Barents cishe ingatshintshanga. Ngapha koko, izihlwele ezahlukeneyo kamsinya mixed.

I-Sea Barents: etyuwa

I-Sea Barents inxibelelene kakuhle ulwandle. Kulo mzekelo obhobhozayo amatsha lizwekazi incinci. Ngenxa kule izalathi etyuwa ezi zilolo hlobo zazilulo kwaye musa kwahluke etyuwa avareji olwandle. Kubalulekile ukuphawula ukuba utshintsho azixhomekekanga kuphela onyaka kodwa kwiingingqi. Umzekelo, kumazantsi-ntshona yinxalenye waphawula etyuwa iphezulu kuLwandle Barents. Apha, i-nani 35 ‰. Yindawo le kumkhombe North Koloni. Kukho ezinetyuwa kwabo amanzi Atlantic bangaze ngumkhenkce.

Kumazantsi kwaye esemantla komsebenzi ukuhla ukuya 34,5 ‰. Kule ndawo kubonisiwe ukunyibilika omkhenkce. Xa mpuma inginginya amanzi acocekileyo ngakumbi. Kule ndawo kuLwandle Barents ubutyuwa kwiindawo million nama-32-33 ‰. Kukho iphawulwe umlambo flow esikhulu samanzi acocekileyo. Kule ndawo kukho kwakhona ukunyibilika omkhenkce.

Le etyuwa kunye ungqameko

Utshintsho kwi etyuwa kwikholam amanzi kuxhomekeke imijelo kwabo amanzi Atlantic, emlanjeni amdaka, kwakunye ukusuka ezantsi isiqabu. Ngelo kwamanzi, lingakumela ukusuka kuma-34 ‰ okanye ngaphezulu, kwaye emazantsi - phezulu ukuya 35.2 ‰. Kwiinguqu ezininzi ezincinci kuqatshelwe ngaphakathi ngwenya ngasentla ahlangabezana nkqo.

Kubalulekile ukuphawula ukuba phantse akukho tshintsho ngexesha nezikhombisi ngexesha lumtyuba. Utshintsho ababuthathaka kakhulu. Umaleko ubuso eliqhelekileyo kakhulu ehlotyeni. Ukunyuka ngokukhawuleza etyuwa ejulile nto ndazigcina ezinzulwini 25-30 eemitha. Ebusika, Jump efanayo phantse walungisa. Xa inxalenye womzantsi-mpuma ubunzulu utshintsho eziphawulwe kakuhle indices etyuwa. Kubalulekile ukukhumbula ukuba iindawo ezinjalo umahluko inokuba PPM ezimbalwa.

Ebusika, izikhombisi ulungelelwaniso waphawula phantse yonke ububanzi kuLwandle Barents. Entwasahlobo, umaleko kumphezulu uba tyaba. Ehlotyeni yale nkqubo tiyisiwa ngenxa ngumkhenkce zinyibilike. nto phakathi imimango 10-25 kwakukho jump elibukhali kwi etyuwa oko.

Ukuxinana kwamanzi

Ukongezelela, musa ukulibala malunga nezinye izinto. Umzekelo, kummandla North Sea ngexesha lasebusika izihlwele yamanzi luthe, kwaye kwindawo esembindini - ehlotyeni. Kulo mzekelo, izizathu le meko zahluke kakhulu. Emantla, oko kwenzeka ngenxa nokufumana amanzi acocekileyo, nakwelasezantsi - ngenxa yobushushu.

Le etyuwa ye Barents Sea ngamaxesha onyaka

Xa index ebusika kulo mmandla ulwandle eliphezulu kwaye 35 ‰. Mncinanana kubo bonke inxalenye emzantsi-mpuma - ukuya ku-33 ‰. Oku kungenxa ekungeneni elikhulu izihlwele Atlantic, ukuhla amanzi elizwekazi ukuyilwa omkhulu ngumkhenkce. rates Spring kuhlala etyuwa eliphezulu. Le Ngaphandle kuphela isiqwenga lonxweme elimxinwa kummandla Kanin-Kolguev kunye nonxweme Murmansk. Apha, ubutyuwa kunciphisa.

Ehlotyeni kukho ukungena kwabo amanzi avela Atlantic Ocean, ukunyibilika komkhenkce kunye nokuhanjiswa kwamanzi omlambo. Ngenxa yale mzobo liyehla kakhulu. Xa inxalenye kumzantsi-mpuma we-mark kuwela 25 ‰, nakwelasezantsi-ntshona - ukuya 34,5 ‰. Xa kokuwa indices Kwakhona agcinwe lifinyele. Noko ke, ngenxa yokuba amanzi lizwekazi ngcembe ebizwa ngokuba yimetabolism isenokucotha, ubutyuwa oLwandle Barents e ipesenti ukunyuka. Ukongeza, ukuyilwa ngokukhawuleza ice iqala kweli xesha. Ngokuthe ngcembe umlinganiselo etyuwa kufikelela kwinqanaba lasebusika.

Ekupheleni

Ke kaloku, ukuba uyazi ukuba yintoni na ubutyuwa koLwandle Barents kwaye kuchaphazela. Nangona okunzulu ezinjalo, kuba iqulathe malunga 110 iintlobo yeentlanzi. Ngeentlobo sehlile entshona ukuya empuma. Oku esidityaniswe lobushushu zinciphise amanzi kunye nomoya, kwaye imo ngumkhenkce. Kubalulekile ukuphawula ukuba Barents Sea cod unika izixeko ezininzi, Bychkova kunye neentlobo flatfish. Okwangoku, kukho into geni haddock, capelin, herring, halibut, cod, catfish, cod polar kunye redfish.
