Spatial And Temporal Mapping Of Distributed Precipitation, Surface And Groundwater Stable Isotopes Enables Insights Into Hydrologic Processes Operating At A Catchment Scale, Alison Cole

Masters Theses

Isotopic analyses of d¹⁸O and d²H of water through the hydrologic cycle have allowed hydrologists to make better interpretations related to climate and relationships between precipitation, surface water, and groundwater. In this study 394 precipitation samples 1917 surface water samples and 1405 groundwater samples across Massachusetts was used to create an isoscape for each respective water. All samples have been collected by volunteers throughout Massachusetts. A state meteoric water line: d²H = 7.7*d¹⁸O + 9.8, surface water line: d²H = 5.7*d¹⁸O – 4.2, and groundwater line: d^{2 …}
