Measured and modelled source water δ18O based on tree-ring cellulose of larch and pine trees from the permafrost zone

iForest - Biogeosciences and Forestry, 2020
To identify source water for trees growing on permafrost in Siberia, we applied mechanistic models that quantify physical and biochemical fractionation processes, leading to oxygen isotope variation (δ18O) in plant organic matter. These models allowed us
