Seasonal variation in deuterium and oxygen-18 concentrations of water vapor and precipitation over the Antarctic
D and 18O distributions were investigated in Antarctic precipitation (falling snow) and in water vapour to study their dependance on season and sampling site. Long-term sampling at the former German Georg Forster Station during 1978–93 and at the Japanese Syowa Station during 1994–97 allow conclusio...
