Use of water isotopes tracers in high latitude hydrology and paleohydrology

ISOTOPES IN PALEOLIMNOLOGY
Lake sediments contain information about isotopic water content
Isotopic fractionation of water in the hydrological cycle arises because of differences in the behavior of water molecules containing various combinations of the naturally occurring stable isotopes of hydrogen (1H, 2H) and oxygen (16O, 17O, 18O).

ISOTOPES IN PALEOLIMNOLOGY
Lake sediments can be used to reconstruct past hydrology and
hydroclimatology at high latitudes.
Provides information about runoff generation processes and surface water balance
