Oxygen Isotopic Composition of the Surface Snow in Mizuho Plateau
Oxygen isotopic compositions of new-fallen snow collected at Syowa Station, and drifting snow at Mizuho Camp and various stations in Mizuho Plateau were determined. Daily variation of oxygen isotopic composition of new snow at Syowa Station is caused mainly by the supply of ^<18>O-rich water v...
