 note = {P(論文), In order to support the GRIP deep drilling, a permanent camp was erected on top of the Greenland ice sheet at an elevation of more than 3km, 800km away from the nearest airport. Day temperatures reached a maximum of -10℃, with typical night temperatures of -30℃. Although the camp was manned only during the three summer months, it was designed to sustain winter temperatures of -60℃. The camp was designed to accommodate 30 people (although the number of inhabitants at times was up to 50), and to include everything needed for the operation, including a 3km long skiway. The designed lifetime of the camp was 3 years, corresponding to 4 field seasons.},
