Har zuwa karni na 19 AD, ba a san nahiyar sosai ba. Har ma akwai tatsuniyoyi cewa akwai wani yankin da ba a san shi ba a kudancin Australiya, wanda ke cike da dusar ƙanƙara da kankara. Kuma bayan shekaru 100 kawai, balaguron farko ya fara, amma tunda kayan aiki kamar haka babu su a lokacin, kusan babu ma'ana a cikin irin wannan binciken.

Tarihin bincike

Duk da cewa akwai kusan bayanai game da wurin da irin wannan ƙasar ta kudu ta Ostiraliya, binciken ƙasar na dogon lokaci ba a yi masa alama da nasara ba.

Wadannan maganganun James Cook ne suka jinkirta ci gaba da bincike a wannan yankin - tsawon rabin karni, ba a sake tura balaguron nan ba. Koyaya, mafarautan hatimi sun sami babban garken hatimai a Tsibirin Antarctic kuma sun ci gaba da yawo a waɗannan yankuna. Amma, tare da gaskiyar cewa sha'awar su kawai ta masana'antu ce, babu wani ci gaban kimiyya.

A zahiri, gano Antarctica da kuma nazarin yankin ya dace da masana kimiyyar Rasha, tunda sune suka fara dawo da balaguro zuwa wannan yankin.

Binciken Antarctica da masana kimiyyar Rasha suka yi

Masu jirgin ruwan Rasha ne suka yi tambaya game da ƙarshen Cook kuma suka yanke shawarar ci gaba da nazarin Antarctica. Tunanin cewa duniya tana nan har yanzu, kuma James Cook yayi kuskure sosai a cikin abubuwan da ya kawo, wadanda masana kimiyya na Rasha Golovnin, Sarychev da Kruzenshtern suka bayyana a baya.
