第19次南極地域観測隊で夏期に実施した重力観測の概要を報告する.1977年12月30日から1978年1月14日まで,昭和基地北東方220kmの竜宮岬地域の野外調査を実施したが,この地域に6点の重力測定点を設置した.また,東オングル島46点,西オングル島5点,ネスオイヤ島2点の重力測定も実施した.データ処理はすべて日本重力観測網(JGSN 75)と正規重力式1967を用いた. Gravity survey was carried out in Cape Ryugu, and East and West Ongul Islands by the summer party of the 19th Japanese Antarctic Research Expedition (JARE-19) using a LaCoste and Romberg model G land gravity meter. Six gravity stations were established in Cape Ryugu on January 8, 1978. Gravity measurements at forty-six points in East Ongul Island were carried out at the end of January. The survey in West Ongul Island was made on February 6. Gravity data processing was made based on the International Gravity Standard Network (IGSN 71) and Japan Gravity Standard Network (JGSN 75).
