Abstract: 17O-excess is a new frontier of water stable isotope studies , which has been drawn attention to over polar regions. This paper first systematically introduces the basic principle and experimental method of 17O-excess in the hydrological cycle. And then the latest research progresses of 17O-excess in snow/ice over polar regions, including the influence factors, spatial distribution, seasonal variations, and the last glacial-interglacial evolution of 17O-excess records in ice cores, are summarized. Finally, the future work on 17Oexcess is prospected based on the existing scientific issues in respect of 17O-excess.

Key words: polar regions, stable isotopes, 17O-excess in snow and ice
