ULwandle lwaseBarents

Ukuxhaphaza i-hydrocarbon

Namhlanje siza kuthetha ulwandle lwebarents. Inxalenye yoLwandlekazi i-Arctic Glacial Ocean kwaye inabela ngaphezulu kummandla onomphezulu we-1.4 yezigidi zeekhilomitha ezizikwere. Olu lwandle luyaziwa ngobuninzi beentlobo zezilwanyana nezilwanyana kunye nomdla woqoqosho. Yayisele isaziwa kumaxesha aphakathi kwiiVikings naseRussia. Ke ngoko, siza kunikezela eli nqaku ukukuxelela zonke iimpawu nokubaluleka kolu lwandle.

Ukuba ufuna ukwazi ngakumbi malunga noLwandle lweBarents, le yiposti yakho.

Iimpawu eziphambili

ulwandle lwebarents

Yenziwe njengexande kwaye ilinganisa i-1300 yeekhilomitha ubude ukusuka emantla ukuya emazantsi. Ime kumhlaba kaFrancisco José ukuya kulwandle olumhlophe. Kwelinye icala, inobubanzi obumalunga ne-1050 yeekhilomitha ukusuka empuma ukuya entshona kwaye ibaleka ukusuka kwiziqithi zeNew Zembla ukuya kuLwandle lwaseNorway.

Inobunzulu beemitha ezingama-230 kuphela kwi-avareji. Oku kuyenza ibe lulwandle olunzulu kakhulu, kodwa kwezinye iindawo inokufikelela kwiimitha ezingama-600 ubunzulu. Amanzi aphakathi kwamazwe aseFinnmark eNorway kunye nonxweme lwaseKarelian lwaseRussia. Njengoko besesitshilo ngaphambilana, olu lwandle lwalusaziwa ngamaVikings naseRussia kodwa babengalubizi uLwandle lwaseBarents, balubiza ngokuba luLwandle lwaseMurmean. Igama loLwandle lweBarents lavela kwimephu ezotywe ngo-1653 ukuhlonipha umhloli wamazwe ongumDatshi uWillem Barents. Lo mhloli wamanzi waselunxwemeni wasemazantsi ukhangela indlela yokuhamba phakathi kweYurophu noMntla Asia.

Uninzi lwezinto ezifunyaniswe zizazinzulu nakumhlaba zakudala zazinikezelwa ngeenjongo ezahlukileyo kunalezo zazifezekisiwe. Ukusuka apho ukuya eColumbus ukufumanisa iMelika. Yintoni ebonisa olu lwandle kukuba lunetyuwa elingaphezulu komndilili. Ngokukodwa i-3,4% yetyuwa. Ngokubhekisele kwimozulu, eyona iphambili kulo mmandla lolu hlobo lwe-subarctic. Ukuba kwiindawo ezikufuphi neNorth Pole, amaqondo obushushu aphakathi ebusika ngama - 25 degrees kwindawo esemantla kunye -8 degrees kwiindawo ezikufutshane nelizwekazi. Oku kuhlala apho, kodwa ehlotyeni banamaqondo obushushu asezantsi kakhulu ajikeleze iidigri ze-0 kummandla osemantla kunye ne-10 degrees kwindawo yelizwekazi.

Olunye lweempawu ezenza ukuba olu lwandle lukhetheke ngakumbi kukuba kukho iindawo ezingaphezulu ezisemantla ezinomkhenkce ngokusisigxina. Ingathi yinxalenye yeNcam eseMantla. Kuba iGulf Stream ithwala amanzi afudumeleyo asentshona, iindawo eziselunxwemeni ezisemazantsi nasentshona zoLwandle i-Barents zingena mkhenkce unyaka wonke. Ngokubhekisele kwimvula, amanqanaba ngonyaka ajikeleze amaxabiso awohlukeneyo kumantla nakwindawo esemazantsi. Inxalenye esemazantsi ifumile ngakumbi ngamaxabiso emvula angama-2500 mm, ngelixa emantla angama-1000 mm kuphela.

Amazibuko oLwandle iBarents

Amaphenyane okuloba oLwandle iBarents

Unxweme lolwandle luzele yimimandla enamawa amakhulu kunye neefjords ezinzulu. Ngaphezulu kwayo yonke amanqanaba enxalenye yasentshona. Nangona kunjalo, empuma yeKanin Peninsula, unxweme alunamawa amaninzi kodwa asezantsi, lubonisa iindawo ezingaphezulu kunye neendawo ezingena nzulu.

Inxalenye yamanxweme ee-archipelagos esemantla aneentaba eziphakamileyo kunye nezineentaba ezininzi zomkhenkce esiphelo sazo lulwandle. Lo mmandla ukwangumdla kwezorhwebo kwaye amazibuko aphambili angenamkhenkce wokurhweba ngala alandelayo:

  • Izibuko laseTromsø neVardø eNorway kufutshane noMntla Koloni.
  • Izibuko laseMurmansk kunye neTeriberka eRashiya, zombini kwiKola Peninsula.

Inani elikhulu lekhowudi enkulu kunazo zonke kwihlabathi lihlala lithengiswa kwezi zibuko. Kungenxa yokuba kukho inani elikhulu leentlanzi kwaye ushishino lokuloba belulawulwa ngokudibeneyo yiRashiya neNorway ukusukela ngo-1976. Ukunciphisa umda wokuloba nokungonakalisi abantu, inani eliphezulu leentlanzi ezivunyelweyo ngonyaka sele limiselwe. Ke, umjikelo wokuvelisa kwakhona we-cod awuphazanyiswa kwaye abantu abakhoyo kolu lwandle abasemngciphekweni.

Kwelinye icala, iNorway yaqala ukukhangela iihydrocarbons kuLwandle i-Barents ngo-1969. Oku kuye kwakhokelela Uxhaphazo lokwenene lokutshintshiselana ngegesi kunye neoyile apho kubonakala khona intsimi yegesi yeShtokman, Le yeyona dipozithi yesihlanu ngobukhulu emhlabeni. Ingxaki yoku kuxhaphaza kungcoliseko kunye nolwakhiwo lwezixhobo embindini wolwandle ezibangela iimpembelelo ezahlukeneyo kwindalo. Iintlobo zezityalo nezilwanyana ezingqongileyo zonakaliswa kukuchitheka okuncinci okwenzeka rhoqo kwiindawo ezisebenzisa ioyile negesi, kunye nengxolo.

Khumbula ukuba izilwanyana ezininzi zinendlela yonxibelelwano esekwe kumaza abonwa ngengxolo. Ukugqithisa koomatshini kulwandle oluvulekileyo kubangela ukungazinzi kwezi radar zendalo zezilwanyana.

Iintyatyambo kunye nezilwanyana zoLwandle iBarents

ii-barents eziqingqiweyo zolwandle

Ngoku siza kuchaza ezona ntlobo ziphambili sinokuzifumana kolu lwandle. Uninzi lwezinto eziphilayo ezifumaneka emanzini afudumeleyo eGulf Stream nakumanzi abandayo eArctic. Ezi ziphilayo ezihlala kwezona ndawo zigqwesileyo zilungelelaniswe neemeko zokuhlala elwandle.

I-Phytoplankton isebenza njengokutya kwe-zooplankton kwaye, yona, Sisiseko sokutya samaxesha amaninzi esifana nekhowudi kunye nezilwanyana ezanyisayo ezifana nomnenga. Umnenga yenye yezona zinto zichaphazeleka ngokukhutshwa kweehydrocarbon. Ezinye iintlobo zigqamile kolu lwandle ezifana netywina laseGreenland kwaye, phakathi kweentaka, ukubonwa okuqhelekileyo kuyabonakala.

Njengoko ubona, olu lwandle lunentabalala yobutyebi kunye neentlobo ngeentlobo zezinto eziphilayo. Ndiyathemba ukuba ngolwazi olunje ungafunda ngakumbi malunga noLwandle iBarents kunye nokubaluleka kokuxhaphaza i-hydrocarbon kunye norhwebo.
