Summer party of the 31st Japanese Antarctic Research Expedition (JARE-31) carried out maintenance of automatic meteorological stations, glaciological observation, and drilling test for "Antarctic Climate Research (ACR)" Project from late December 1989 to January 1990 around the Sφr Rondane Mountains region. This party is constituted by four glaciologists including two Belgian observers and one JARE-30 member. Three prototypes of electromechanical ice drill for deep core sampling using untifreezing liquid were successfully tested on a bare glacier at Jenningsbreen (Jennings glacier). On the same glacier, dynamics of glacier movement were studied by Belgian observers. Mass balance measurement was conducted on Goosen-breen (Goosen glacier) of Brattnipene. Two helicopters were employed for geological and topographical survey in the Sφr Rondane region, so that we were able to fly to Nansenisen, south of Sφr Rondane, and to obtain surface bare ice within dust band (volcanic ash?).
