Stable water isotope compositions within the Chihuahuan Desert (Trans-Pecos region, Texas, USA)

Cacti water isotope compositions are contextualized within a regional (i.e., Trans-Pecos region, Texas, USA) hydrologic (i.e., 20 to 25-yr record of precipitation amount, air and river temperature, surface water and spring discharge, and groundwater level) and isotopic context (i.e., precipitation, soil water, groundwater, surface water, and tap water as a groundwater proxy).
