Oxygen isotope profiles of deposited snow in different depositional environments of the Antarctic ice sheet

Antarctic Record, 1991
Vertical profiles of oxygen isotopic contents in deposited snow were obtained in the region where katabatic winds prevail (Mizuho Station : 70.7°S, 44.3°E, 2230m), the inland dome-like plateau (Dome Camp : 77.0°S, 35.0°E, 3761m) and the transitional zone

Discovery of Meteorites near Yamato Mountains, East Antarctica

Antarctic Record, 1971
1969年12月,第10次日本南極地域観測隊の内陸調査旅行のさい,筆者らはやまと山脈南東,南緯71°50',東経36°15'付近の裸氷斜面上で隕石を9箇発見,採集した.これは,隕石採集を主目的として,計画的になされたものではないので,隕石の分布ひんどはかなり高そうである.この付近の地域や,類似の氷床の構造のところでは,今後も発見できそうである.採集された隕石はエコンドライト1箇,コンドライト8箇で,岩質からみて,少なくとも6種類(コンドライト5種,エコンドライト1種)の隕石である.
