Namuhla sizokhuluma ngakho ulwandle olwandle. Iyingxenye ye-Arctic Glacial Ocean futhi inweba ngaphezu kwendawo enobuso obungamakhilomitha-skwele ayizigidi eziyi-1.4. Lolu lwandle lwaziwa ngobuningi balo bezinhlobo zezimila nezilwane nezintshisekelo zalo kwezomnotho. Yayivele yaziwa ngezikhathi zasendulo kumaViking naseRussia. Ngakho-ke, sizonikezela le ndatshana ukukutshela zonke izici nokubaluleka kwalolu lwandle.
Uma ufuna ukwazi kabanzi ngoLwandle iBarents, lokhu okuthunyelwe kwakho.
Izici eziyinhloko
Ibunjwe njengonxande futhi ilinganisa amakhilomitha ayi-1300 ubude ukusuka enyakatho kuye eningizimu. Itholakala ezweni laseFrancisco José kuya olwandle olumhlophe. Ngakolunye uhlangothi, inobubanzi obungamakhilomitha angaba ngu-1050 XNUMX ukusuka empumalanga kuya entshonalanga futhi usuka eziqhingini zaseNew Zembla uye oLwandle lwaseNorway.
Inokujula kwamamitha ayi-230 kuphela ngokwesilinganiso. Lokhu kuyenza ibe ulwandle olungajulile kakhulu, kodwa kwezinye izindawo lungafinyelela kumamitha angama-600 ukujula. Amanzi aphakathi kwamazwe aseFinnmark eNorway kanye nogu lwaseKarelian lwaseRussia. Njengoba sike sasho phambilini, lolu lwandle lwalwaziwa ngamaViking kanye nabantu baseRussia kepha bengalubizi ngoLwandle iBarents, balubiza ngoLwandle iMurmean. Igama loLwandle iBarents lavela emephini edwetshwe ngo-1653 ukuhlonipha umhloli wamazwe waseDashi uWillem Barents. Lo mhloli osebeni oluseningizimu ukuze afune indlela yokuhamba phakathi kweYurophu neNyakatho ye-Asia.
Iningi lezinto ezitholwe yisayensi nezindawo zakudala zanikezwa ngenhloso ehlukile kunaleyo efinyelelwe. Ukusuka lapho kuye eColumbus ukuthola iMelika. Yini ehlukanisa lolu lwandle ukuthi lunosawoti ongaphezu kwesilinganiso. Ngokukhethekile u-3,4% usawoti. Ngokuqondene nesimo sezulu, esivelele esifundeni lolu hlobo lwaseningizimu. Ukuba sezindaweni eziseduze kwesigxobo esisenyakatho, amazinga okushisa aphakathi nendawo ebusika angama -25 degrees endaweni esenyakatho kakhulu nama -8 degrees ezindaweni eziseduzane nezwekazi. Lokhu kuhlala lapho, kepha ehlobo futhi banamazinga okushisa aphansi kakhulu acishe abe ngu-0 degrees endaweni esenyakatho kanye nama-10 degrees endaweni yezwekazi.
Esinye sezici ezenza lolu lwandle lukhetheke ukuthi kunezindawo eziningi ezisenyakatho ezifriziwe unomphela. Kufana nokuthi yingxenye yeNorth Pole. Ngoba iGulf Stream ithwala uquqaba lwamanzi afudumele ukusuka entshonalanga, izindawo ezisogwini oluseningizimu nasentshonalanga yoLwandle iBarents zingenaqhwa unyaka wonke. Mayelana nemvula, amazinga wonyaka azungeze amanani ahlukene engxenyeni esenyakatho nengxenye eseningizimu. Ingxenye eseningizimu inomswakama omningi ngamanani emvula angama-2500 mm, kanti enyakatho kunamanani ayi-1000 mm kuphela.
Amachweba aseBarents Sea
Ogwini lolwandle kugcwele izindawo ezinamawa amakhulu namachweba ajulile. Ngaphezu kwakho konke amazinga engxenye esentshonalanga. Kodwa-ke, empumalanga yeNhlonhlo YaseKinin, ugu alunawo amawa amaningi kodwa luphansi, luveza amatheku amaningi nezindawo zokungena ezingajulile.
Ingxenye yamaphethelo eziqhingi ezisenyakatho inezintaba eziphakeme futhi eziphakeme ezinezinguzunga zeqhwa eziningi ukuphela kwazo ulwandle. Le ndawo futhi inesithakazelo kwezentengiselwano futhi amachweba amakhulu angenawo amaqhwa okuhweba yiwo alandelayo:
- Itheku laseTromsø neVardø eNorway ngaseNyakatho Kapa.
- Itheku laseMurmansk naseTeriberka eRussia, zombili esiQhingini saseKola.
Inani elikhulu lekhodi enkulu kunazo zonke emhlabeni livame ukuthengiswa kulawa machweba. Lokhu kungenxa yokuthi kunenqwaba yalezi zinhlanzi futhi le ndawo yokudoba ibiphethwe ngokubambisana yiRussia neNorway kusukela ngo-1976. Ukuze kuncishiswe ukudotshwa kungalimazi inani labantu, isibalo esiphezulu sezinhlanzi ezivumelekile ngonyaka sesisunguliwe. Ngale ndlela, umjikelezo wokukhiqiza kabusha i-cod awuphazanyiswa futhi abantu abakhona kulolu lwandle abekho engozini.
Ngakolunye uhlangothi, iNorway yaqala ukuhlola ama-hydrocarbon oLwandle iBarents ngo-1969. Lokhu kuye kwaholela ukuxhashazwa kwangempela kokushintshaniswa kwegesi nowoyela lapho kugqama khona insimu yegesi iStoktman, lokhu kuyidiphozi yesihlanu ngobukhulu emhlabeni. Inkinga yalokhu kuxhashazwa kungukungcola nokwakhiwa kwengqalasizinda maphakathi nolwandle okudala imithelela eyahlukahlukene ku-ecosystem. Izinhlobo zezitshalo nezilwane ezizungezile zilinyazwa ukuchitheka okuncane okuhlala kwenzeka ezindaweni lapho kusetshenziswa khona uwoyela negesi, nangomsindo.
Khumbula ukuthi izilwane eziningi zinendlela yokuxhumana ngokususelwa kumagagasi abonwa ngomsindo. Ukweqiwa kwemishini olwandle oluvulekile kubangela ukungazinzi kulawa ma-radar emvelo ezilwane.
Izimbali nezilwane zoLwandle iBarents
Manje sizochaza izinhlobo eziyinhloko esingazithola kulolu lwandle. Iningi lezinhlobonhlobo zezinto eziphilayo litholakala emanzini apholile eGulf Stream nasemanzini abandayo e-Arctic. Lezi zidalwa ezihlala ezindaweni ezimbi kakhulu zivumelaniswa nezimo zezindawo zasolwandle.
I-Phytoplankton isebenza njengokudla kwe-zooplankton futhi, Kuyisisekelo sokudla sezikhathi eziningi njenge-cod nezilwane ezincelisayo ezifana nomkhomo. Umkhomo ungenye yezinto ezithinteka kakhulu ekukhipheni ama-hydrocarbon. Ezinye izinhlobo zigqama kulolu lwandle njengophawu lweGreenland futhi, phakathi kwezinyoni, imurre ejwayelekile iyabonakala.
Njengoba ukwazi ukubona, lolu lwandle lunengcebo eningi nezinhlobonhlobo zezinto eziphilayo. Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi ngoLwandle iBarents kanye nokubaluleka kokuxhashazwa kwe-hydrocarbon nokuhweba.
