Peshek, Catherine Triple oxygen isotopes of soil water and soil carbonates: evaporation experiment, numerical modeling, and natural carbonate samples Mendeley Data We investigated how the triple oxygen isotope composition of soil water evolves due to transient evaporation and how the isotopic composition of soil water is recorded by soil carbonates. We used these data to calibrate a numerical soil evaporation model. Our model-data comparison shows that the isotopic composition of soil water evolves as the evaporation front migrates deeper below the surface over time. The evaporation front is recognized by the maximum isotopic offset from meteoric water, recorded by both oxygen-18 and oxygen-17 (triple oxygen). Model application to soil carbonate profiles reveal that soil carbonates to do record the full extent of isotopic fractionation due to evaporation.
