Using stable water isotopes to understand ecohydrological pathways in changing Arctic watersheds

Abstract

Stable water isotopes of 2H and 18O have long been used in studying the hydrological cycle. The drastic change Arctic environments are experiencing revolves largely around storage and cycle changes of fresh water, affecting the ecohydrological features in the whole watershed. By simultaneously studying the hydrological changes with isotopes as well as the biological activity in the river, a more comprehensive picture on the effects of climate change in the Arctic can be predicted.
