Two ice cores (83.92m and 24.41m depth) were obtained at one of the highest areas (Snofjellafonna) in the western part of Spitsbergen in Svalbard by the Japanese Arctic Glaciological Expedition, 1992, with cooperation from the Norwegian Polar Research Institute. Firn-layers were observed in ice cores from the surface to 30m depth; these layers gradually densified and turned to ice below that depth. Refreezing ice layers were observed from the surface to the bottom of ice cores; these layers were originally formed by refreezing of melt water in firn layers near the surface of the icefield. In the electrical conductivity profile of ice cores, peaks at two depths (18m, 34.5m) were well identified. The ice temperatures in the 24.41m borehole ranged from -3.36℃ to -0.75℃. The ice temperatures in the 83.92m borehole ranged from -1.47℃ to 0.00℃. Subnurface water was found below 21.46m depth in the 24.41m borehole. After 18 liters of water was drained from the 24.41m borehole, the rate of rise of water level in the borehole was observed.
