For many of the Siberian rivers, and the Upper Ob in particular, 70?80% of the volume of the annual water runoff is formed during the spring flood. Thus, factors influencing the formation of water runoff during the spring flood are paramount. We explain ...

A snowpack?s d2H and d18O values evolve with snowfall, sublimation, evaporation, and melt, which produces temporally variable snowpack, snowmelt, and runoff isotope signals. As a snowpack ages, the relatively depleted d2H and d18O values of snow will bec...
