Stable oxygen and hydrogen isotopes, also called stable water isotopes, are among the best proxies for paleoclimate research widely used in geosciences including the fields of glaciology, paleolimnology, hydrology among others, and since the 1990s also in permafrost research. The key aspect of this research direction is the temperature-dependency of stable isotope fractionation for the phase transitions of water (i.e. evaporation, condensation), which can be used to derive relative (and potentially absolute) temperature variations. Isotope monitoring has been expanded to the Lena River, which shows the seasonal aspects of hydrological changes (i.e. during ice break-up, snow melt, precipitation/evaporation ratio ...) in the hinterland of the Lena.
