Antarctica ndi kondomu yodabwitsa yomwe ili ndi chilengedwe chapadera. Pali madamu achilendo pano, omwe ndi ofunika kuwunikira Lake Vostok. Amadziwika ndi dzina loti station ya Vostok, yomwe ili pafupi. Nyanjayi ili ndi ayezi wokutidwa pamwamba. Malo ake ndi 15.5 ma mita lalikulu. makilomita. Kum'mawa ndi madzi akuya kwambiri, popeza kuya kwake kuli pafupifupi mita 1200. Madzi m'nyanjayi ndi abwino komanso okhutitsidwa ndi mpweya, ndipo mwakuya amatha kutentha bwino, chifukwa amatenthedwa kuchokera kumagwero otentha.
Kupeza nyanja ku Antarctica
Nyanja Vostok idapezeka kumapeto kwa zaka za m'ma 1900. Wolemba mbiri yaku Soviet, Russia komanso geomorphologist A. Kapitsa adati pansi pa ayezi pakhoza kukhala njira zosiyanasiyana zopumulira, ndipo m'malo ena payenera kukhala matupi amadzi. Lingaliro lake linatsimikiziridwa mu 1996, pomwe nyanjayi idapezeka pafupi ndi siteshoni ya Vostok. Pachifukwa ichi, kuwomba kwa ayezi kunagwiritsidwa ntchito. Chitsimecho chinayamba mu 1989, ndipo popita nthawi, chafika pamtunda wopitilira 3 zikwi mita, ayezi adatengedwa kukafufuza, zomwe zidawonetsa kuti awa ndi madzi oundana am'madzi oundana.
Mu 1999, kuboola chitsime kudayimitsidwa. Asayansiwo adaganiza kuti asasokoneze zachilengedwe kuti zisawononge madzi. Pambuyo pake, ukadaulo wowononga zachilengedwe woboola chitsime mu glacier udapangidwa, womwe umalola kuti kubooleza kupitirire. Popeza zida ziwonongeka nthawi ndi nthawi, ntchitoyi idakulitsidwa kwa zaka zingapo. Asayansi anali ndi mwayi wofikira pamwamba pa nyanjayi koyambirira kwa 2012.
Pambuyo pake, zitsanzo zamadzi zidatengedwa kuti zikafufuzidwe. Adawonetsa kuti m'nyanjayi muli zamoyo, zomwe ndi mitundu ingapo ya mabakiteriya. Anayamba kudzipatula patokha ndi zachilengedwe zina zapadziko lapansi, motero sadziwika ndi sayansi yamakono. Maselo ena amakhulupirira kuti ndi a nyama zamagulu angapo monga ma molluscs. Mabakiteriya ena omwe amapezeka ndi tizilomboto ta nsomba, chifukwa chake nsomba mwina zimatha kukhala pansi pa Nyanja Vostok.
Mpumulo m'dera la nyanjayi
Nyanja Vostok ndichinthu chomwe chikuwunikiridwa mwakhama mpaka pano, ndipo zinthu zambiri m'chilengedwechi sizinakhazikitsidwe. Posachedwa, mapu adapangidwa akuwonetsa kupumula ndi mawonekedwe am'mbali mwa nyanja. Zilumba za 11 zidapezeka m'derali. Mtsinje wapansi pamadzi unagawaniza pansi pa nyanjayo magawo awiri. Mwambiri, zachilengedwe za Nyanja Kum'mawa kuli zakudya zochepa. Izi zimapangitsa kuti mosungira mosakhalitsa mukhale zamoyo zochepa, koma palibe amene akudziwa zomwe zidzapezeke munyanjayo pakufufuza kwina.
