Activities of the summer party of the 17th Japanese Antarctic Research Expedition in 1975-1976

Abstract

Summer operation of the 17th Japanese Antarctic Research Expedition (JARE-17) is outlined. The expedition led by T. YOSHINO consisted of 40 members, 10 of which are of the summer party led by T. HIRASAWA, deputy leader of the expedition. After leaving Fremantle in Australia, the icebreaker FUJI reached a site 53 nautical miles north of Syowa Station on January 3,1976. All of the cargo for the 17th expedition was transported to Syowa Station until February 18,1976,while the construction work was carried out at Syowa Station. On February 1,1976,the wintering members of JARE-17 took over the duties at the station. Oceanographic and biological observations were carried out throughout the voyage, and also marine geographical studies were conducted within the sea ice area. Several field parties for geographical, biological and geodetic surveys were sent to exposed rocks around Syowa Station. A round trip to the inland Mizuho Station (formally Mizuho Camp, officially redesignated in March 1978) was carried out to deliver the cargo. Two rockets for the studies of upper atmosphere physics were launched at Syowa Station during the summer season.
