| 内容記述 | Two ice cores (184.62m and 49.21m depth) were drilled in the middle area of Åsgardfonna, northeastern part of Svalbard, by the Japanese Arctic Glaciological Expedition, 1993 (JAGE '93). None of them reached to the bedrock. Stratigraphic observation and bulk density measurement were carried out for each ice core at the drilling site. The depth of the firn-ice transition was about 6m. Transparent layers and low density layers indicated the occurrence of several warm and cold climatic conditions in this region. In order to find the cause of the time gap observed in the ice core from Hoghetta, on top of Åsgardfonna, the stratigraphy of both ice cores was compared with each other. Temperature measurements in the boreholes showed a unique profile, that is, it had negative temperature gradient at depths from about 30m to 130m. Numerical calculation using a steady state model was applied to reconstruct the unique profile of ice temperature. | |||||||||||||||||||||
