Polar regions are under dynamic hydrological conditions due to the presence of active layers, which are freezing and thawing repeatedly. This study aims to investigate the hydrological process in a stream of a snow-dominated headwater catchment in King George Island in Antarctica using isotopic and chemical signatures of stream water. We identified that the chemical composition of stream water was correlated to the degree of interaction with soil and rock materials, and the isotopic composition was correlated to the rate of snowmelt rate. Our results showed a negative correlation between electrical conductivity (EC) and streamflow (r=0.65, p<0.0001). Additionally, we also observed a positive correlation between the stable isotopic composition of stream water and streamflow (r=0.64, p<0.0001). Based on these results, it was suggested that the active layer thickness played an important role in interpreting hydrological pathways at the catchment. During the cold summer period, the contribution of supra-permafrost groundwater was domi ... 전체 초록 보기
