Ua ʻike nā ʻepekema mai ka Institute for Marine Research ma Tromso, Nolewai i nā loli wikiwiki a me ka pīhoihoi i ka ʻākau o Barents Sea. Wahi a nā kānaka noiʻi, ke nalowale nei kēia māhele i nā hiʻohiʻona o ke kai Arctic a lilo koke i ʻāpana o ka ʻōnaehana ʻĀkelanika. Ma ka huli, he hopena maikaʻi paha kēia i nā kaiaolaola kūloko kahi e noho ai nā holoholona hilinaʻi hau a hoʻokō ʻia ka lawaiʻa kalepa. Ua paʻi ʻia kahi ʻatikala e nā ʻepekema i loko o ka puke pai ʻo Nature Climate Change.
ʻO ke kai ʻo Barents he ʻelua mau ʻāina me nā aupuni ʻano ʻokoʻa. He anu anuanu ko ke kūkulu ʻākau a me nā kaiaolaola e pili ana i ka hau, ʻoiai e hoʻomalu ʻia ka hema e nā kūlana ʻAkelanika haʻahaʻa. Loaʻa kēia hoʻokaʻawale ma muli o ka komo ʻana o ka wai mehana a me ka paʻakai o ka ʻAkelanika i loko o kahi ʻāpana o ke kai, ʻoiai ka mea ʻē aʻe e komo ana nā wai anuanu a me ke anuanu o ka Arctic, i kēlā me kēia makahiki, ma lalo o ke kaomi o ka mua, hoʻi i ka ʻākau.
Manaʻo nā ʻepekema ʻo ka hana nui i kēia kaʻina e ka haunaele o ka stratification o nā papa wai ma muli o ka emi o ka nui o ka wai hou e komo i ke kai i ka wā o ka hoʻoheheʻe ʻana o ka hau. I ka pōʻaiapuni maʻamau, ke hoʻoheheʻe ka ʻili hau, loaʻa i ka ʻilikai kai ka wai anuanu, kahi e hana ai i nā kūlana no nā pale hau hou e hana i ka hoʻoilo e hiki mai ana. Pale ka hau like i ka papa ʻo Arctic mai ka pili pololei ʻana me ka lewa, a uku hoʻi i ka mana o nā papa Atlantika hohonu, ʻoiai e mālama nei i ka stratification.
Inā ʻaʻole lawa ka wai hoʻoheheʻe, hoʻomaka ka stratification e hoʻohaunaele, a me ka hoʻomehana ʻana a me ka hoʻonui ʻana o ka paʻakai o ke kolamu wai holoʻokoʻa e hoʻomaka i kahi loop feedback maikaʻi e hoʻemi ana i ka uhi o ka hau a, no laila, hāʻawi i ka neʻe hou aku i ka stratification o nā papa, e ʻae ana i nā wai mahana hohonu e piʻi i luna a kiʻekiʻe. Hōʻike nā kānaka ʻepekema i ka hōʻemi maʻamau o ka nui o ka uhi hau i ka Arctic ma muli o ka hoʻomehana honua ma ke ʻano he kumu no ka emi o ke kahe o ka wai hoʻoheheʻe.
Hoʻoholo nā kānaka noiʻi ʻo ka pau ʻana o ka wai hoʻoheheʻe hou ka mea i hoʻomaka ai ke kaulahao o nā hanana i hopena i ka puka ʻana o kahi "wahi wela" ma ka Arctic. I ka manawa like, ʻaʻole hiki ke hoʻololi hou ʻia nā loli, a e lilo koke ke kai Barents i ʻāpana o ka ʻōnaehana ʻĀkelanika. ʻO ia mau hoʻololi i hana wale ʻia i ka wā hau i hala.
