Measurements of density, total gas content, δ18O, and electrical conductivity were carried out along a core 100 m long. A profile of in-situ bubble pressure was obtained from the data on density and total gas content, taking into account the volume relaxation of the core in the period between core recovery and density determination. The bubble pressure was appreciably higher than the overburden pressure at corresponding depths. It was considered that the pressure difference was caused by the continuous lifting of the ice, since ice flow was obstructed in the blue-ice area. From the profile of the pressure difference, the vertical distribution of the upward velocity was calculated, which provided a time-scale for the core. It was found that the 100 m long core represented a record of about 104–105a. Since the surface ice was considered to represent a few tens of thousand years B.P., the data obtained on total gas content, δ18O, and electrical conductivity would describe the variations in the climate as well as in the ice sheet during the last glacial period.
