Hydrological connectivity and seasonal storage change of tundra ponds in a polar oasis environment, Canadian High Arctic
Abstract Tundra ponds are a common type of wetland in the High Arctic. Their preservation is predicated upon ample water supply and storage to overcome evaporation losses. Two years of hydrological study of a cluster of ponds in a polar oasis of the Canadian Arctic showed the dominance of overland f...
