Journal ArticleDOI
Carbon isotope fractionation of dissolved inorganic carbon (DIC) due to outgassing of carbon dioxide from a headwater stream
Daniel H. Doctor,Carol Kendall,Stephen D. Sebestyen,James B. Shanley,Nobuhito Ohte,Elizabeth W. Boyer +5 more
TL;DR: The stable isotopic composition of dissolved inorganic carbon (DIC) was investigated as a potential tracer of streamflow generation processes at the Sleepers River Research Watershed, Vermont, USA as discussed by the authors.
Journal ArticleDOI
Sources, transformations, and hydrological processes that control stream nitrate and dissolved organic matter concentrations during snowmelt in an upland forest
Stephen D. Sebestyen,Elizabeth W. Boyer,James B. Shanley,Carol Kendall,Daniel H. Doctor,George R. Aiken,Nobuhito Ohte +6 more
TL;DR: This article explored catchment processes that control stream nutrient concentrations at an upland forest in northeastern Vermont, USA, where inputs of nitrogen via atmospheric deposition are among the highest in the nation and affect ecosystem functioning.
Book ChapterDOI
Stable isotope applications in hydrologic studies
Carol Kendall,Daniel H. Doctor +1 more
TL;DR: In this article, the authors propose a new algorithm called 5.11.5.0-11.1-5.5-0-0.0/0.00
Journal ArticleDOI
Quantification of karst aquifer discharge components during storm events through end-member mixing analysis using natural chemistry and stable isotopes as tracers
Daniel H. Doctor,Daniel H. Doctor,E. Calvin Alexander,Metka Petrič,Janja Kogovšek,Janko Urbanc,Sonja Lojen,Willibald Stichler +7 more
TL;DR: In this article, the authors used principal components analysis (PCA) and end-member mixing analysis (EMMA) to estimate mixing proportions among three sources: (1) allogenic river recharge, (2) autogenic recharge and (3) an anthropogenic component stored within the epikarst.
Journal ArticleDOI
Tracing sources of nitrate in snowmelt runoff using a high‐resolution isotopic technique
Nobuhito Ohte,Stephen D. Sebestyen,James B. Shanley,Daniel H. Doctor,Carol Kendall,Scott D. Wankel,Elizabeth W. Boyer +6 more
TL;DR: In this article, the authors used denitrifier to determine the dual isotopic composition (δ15N and δ18O) of nitrate in a headwater stream during snowmelt.
