  • In 1993, the 34th wintering party of the Japanese Antarctic Research Expediton (JARE-34) conducted shallow core drilling at Dome Fuji Station, East Antarctica to make a pilot borehole for deep core drilling. Then, an ice core of 112.59 depth was recovered by electro-mechanical drill. The core was brought to the National Institute of Polar Research (NIPR: Tokyo). In 1995, core analysis was started to determine: (1) the recent circumstance of deposition process at Dome Fuji Station, and (2) the formation process of stratigraphic structure and its characteristics in a shallow layer. Chronology, chemical and physical properties are examined. The ECM signal was measured at DF 1250 V and about -15C. The data were corrected to values corresponding to -15C by use of the Arrhenius law for temperature dependence (Neftel, 1985). Density was also corrected for effects of firn density. Analogue ECM data were digitized at 1 mm intervals. After taking the moving average of 10 data, Data set was made at intervals of 1 cm.
