Description
Collection and isotopic analysis of xylem and soil water to determine plant water sources using δ18O and δ2H signatures combined with Bayesian mixing model to quantify proportional contributions from different water pools.
Typical Equipment
- sealed bags
- cryogenic extraction equipment
- batch-distillation apparatus
- Picarro L2140-i analyzer
Output Measurements
- δ18O values
- δ2H values
- snowmelt reliance percentages
