520 ▼a Due to their temperature dependency, stable noble gases (He, Ne, Ar, Kr, and Xe) have been routinely used as indicators of past climate in sedimentary systems for over four decades. However, noble gas studies in fractured systems, where infiltra
520 ▼a Noble gases in the meltwater samples from both the GrIS and the AG are dominated by a partially equilibrated air-saturated water (ASW) component rather than trapped air in the glacial ice. Water source altitudes based on Xe range between 0.8 and
520 ▼a Water samples were collected in Maui from rain events, springs from perched aquifers, and wells tapping the basal aquifer in June 2014 and February 2016. All samples are in disequilibrium with the atmosphere at the collection point and do not re
520 ▼a This dissertation has important scientific implications in the fields of glaciology, hydrogeology, and meteorology.
