Cryogenic vacuum distillation to extract water from plant tissue and mass spectroscopy (equilibration method). Small tree branches were sampled by tree climbing over the course of the season in 2009 and 2011. Samples were sealed in glass vials, frozen, and later the water was extracted from the tissue via cryogenic vacuum distillation. Samples were analyzed at the University of California at Berkeley, Center for Stable Isotope Biogeochemistry by mass spectroscopy, equilibration method.
