Stable Isotope Studies of Lakes

  • F. J. PearsonJr.
  • Tyler B. Coplen


There are natural variations in the ratios of the stable isotopes of many light elements. Isotope ratio differences in substances containing hydrogen (2H/1H, usually written D/H), carbon (13C/12C), nitrogen (15N/14N) oxygen (18O/16O), and sulfur (34S/32S) have been used or have potential use in studies of various aspects of lakes. We give here a general overview of the processes which bring about changes in stable isotope ratios, using studies of lakes as examples of their operation. We have by no means exhausted the literature on isotopes in lake studies.
