Stable isotope development in ground ice along an alpine tundra slope in the Ogilvie Mountains, Yukon Territory
DownloadSpring 2022
Stable isotopic ratios of oxygen and hydrogen (δ18O and δD) from ground ice have been used to reconstruct paleoclimate temperatures spanning the Late Pleistocene and Holocene in subarctic and arctic regions. This is possible due to the strong relations between the isotopic composition of...
