Some Problems in Stratigraphic Analysis of Fir in Mizuho Plateau, East Antarctica (Special Issue of the Proceedings of the First Symposium on Antarctic Meteorology and Glaciology)
Long-term variation of precipitation and surface temperature in the vicinity of Mizuho Station were studied by means of stratigraphic analyses of 150-m boring core. ln this paper, some problems on snow stratigraphy aroused concerning the analyses are discussed. First, problems on the unit of stratif...
