第19次南極地域観測隊夏隊の調査計画の一環として,昭和基地より,220 kmに位置する竜宮岬(南緯67°58'東経44°01')の総合調査が実施された.竜宮岬は日本隊にとっては未知の地域である.調査内容は地球物理,測地,地質,生物にわたっているが,その主眼は地形測量と地質図作成におかれた.また,設営の面では「ふし」が氷海に入ってまもなく,竜宮岬の北方177 km(南緯66°41', 東経45°40.8')の遠距離からヘリコプターによる空輸が行われたことも初めての試みであった.東西の長さ10km,幅2kmの露岩地域全体にわたり,各部門の調査を行うことができた.天測点や10ヵ所の基準点の設置6ヵ所での重力測定,地質の概査,陸上生物の生態調査などを実施した.本報告でぱ各調査内容の概要のほか,設営およびその問題点について論議した. The summer field party of the 19th Japanese Antarctic Research Expedition (JARE-19) camped at Cape Ryugu 220 km east-northeast of Japanese Antarctic Station, Syowa, from December 30th, 1977 to January 14th, 1978. Dr. KAMINUMA of the National Institute of Polar Research, Japan, led the six-man party which contained three geologists, one biologist, one surveyor and one geophysicist. Cape Ryugu located at 67°58'S and 44°01'E, has an ice-free area of 10 km length in the east-west direction with a breadth of 2 km. The survey was the first ground one by the Japanese field party. Therefore, the principal scientific aims of the party were topographic and geological mapping. Other scientific goals were biological and geophysical surveys. The party succeeded in establishing ten topographic control points, one astronomical station, and six gravity stations. Fundamental geological and biological surveys were made throughout the Cape Ryugu ice-free area. Successful air transport to 177 km north from Cape Ryugu was made by two helicopters. A report on the logistics of the field party and a summary of the field survey are also given in this paper.
