He ʻāina pohihihi ʻo Antarctica i loaʻa kahi honua kūlohelohe. Aia kekahi mau waihona ʻokoʻa ma aneʻi, i waena o kahi e pono ai ke kahakai ʻo Lake Vostok. Ua kapa ʻia kona inoa ma hope o ke keʻena ʻo Vostok, aia ma kahi kokoke. Uhi ʻia ka loko i ka pale hau mai luna mai. ʻO kona wahi 15.5 tausani mau mika kūlike. kilomita. ʻO ka Hikina kahi hohonu o ka wai o ka wai, ʻoiai ʻo kona hohonu ma kahi o 1200 mika. ʻO ka wai i loko o ka loko e hou a hoʻonui ʻia me ka oxygen, a ma ka hohonu he mahana maikaʻi kona, no ka mea hoʻomehana ʻia ia mai nā kumu geothermal.
ʻIke ʻia o kahi loko ma Antarctica
ʻIke ʻia ʻo Lake Vostok ma ka hopena o ke kenekulia 20. ʻO ka Soviet, ka mea hulihonua Lūkini a me ka geomorphologist ʻo A. Kapitsa i ʻōlelo ma lalo o ka hau e hiki ke lilo i nā ʻano kōkua like ʻole, a ma kekahi mau wahi e pono ai nā kino wai. Ua hoʻokūpaʻa ʻia kāna kuhiakau i ka makahiki 1996, i ka manawa i ʻike ʻia ai kahi loko subglacial kokoke i ke kahua ʻo Vostok. No kēia, ua hoʻohana ʻia ke kani seismic o ka pale hau. Hoʻomaka ka ʻeli ʻana o ka luawai ma 1989, a i ka hala ʻana o ka manawa, ua hōʻea i kahi hohonu o 3 tausani mau mika, ua lawe ʻia ka hau no ka noiʻi ʻana, a hōʻike ʻia he wai paʻahau ia o kahi loko hau.
I ka makahiki 1999, ua kāpae ʻia ka ʻeli ʻana o ka luawai. Ua hoʻoholo ka ʻepekema ʻaʻole e hoʻopilikia i ke kaiaolaola i ʻole e hoʻohaumia i ka wai. Ma hope mai, ua hoʻomohala ʻia kahi ʻenehana ʻenehana hou aku no ka ʻeli ʻana i kahi luawai i loko o ka glacier, i ʻae ai e hoʻomau i ka ʻeli ʻana. Ma muli o ka wāwahiʻana o nā pono hana, ua hoʻolōʻihi ʻia ke kaʻina hana i loko o kekahi mau makahiki. Ua loaʻa i ka poʻe ʻepekema ka manawa e hiki ai i ka ʻilikai subglacial i ka hoʻomaka mua o 2012.
Ma hope, ua lawe ʻia nā laʻana wai no ka noiʻi. Ua hōʻike lākou aia ke ola i loko o ka loko, ʻo ia kekahi mau ʻano bacteria. Hoʻolālā lākou i kahi kaʻawale mai nā kaiaolaola ʻē aʻe o ka honua, no laila ʻaʻole lākou i ʻike ʻia e ka ʻepekema hou. Manaʻo ʻia kekahi mau hunaola no nā holoholona multicellular e like me molluscs. ʻO nā koʻohune ʻē aʻe i loaʻa he parasite iʻa, a no laila hiki i ka iʻa ke noho i loko o ka hohonu o Lake Vostok.
ʻO ke kōkua ma kahi o ka loko
ʻO Lake Vostok kahi mea e mākaʻikaʻi nui ʻia a hiki i kēia lā, a ʻaʻole i hoʻokumu ʻia nā hiʻohiʻona he nui o kēia kaiaolaola. I kēia mau lā, ua hōʻuluʻulu ʻia kahi palapala ʻāina e hōʻike ana i ke kōkua a me nā kahakaha o nā kahakai. Ua loaʻa nā mokupuni 11 ma ka panalāʻau o ka waihona wai. Ua hoʻokaʻawale kahi pali lalo i ka lalo o ka loko i ʻelua ʻāpana. Ma ka laulā, ke kaiaolaola o Lake Loaʻa i ka Hikina kahi haʻahaʻa haʻahaʻa o nā meaola. Ke alakaʻi nei kēia i ka ʻoiaʻiʻo he kakaikahi nā meaola ola i loko o ka waihona wai, akā ʻaʻohe mea i ʻike i nā mea e loaʻa i ka loko i ka wā o ka noiʻi hou.
