Journal ArticleDOI
Global application of stable hydrogen and oxygen isotopes to wildlife forensics.
TL;DR: The precipitation maps show that the greatest potential for applying hydrogen and oxygen isotope forensics exists in mid- to high-latitude continental regions, where strong spatial isotope gradients exist and where strong, mechanistic relationships link precipitation and isotope ratios in biological tissue exist.
Journal ArticleDOI
Comparative equilibration and online technique for determination of non-exchangeable hydrogen of keratins for use in animal migration studies.
TL;DR: A rapid, low cost, analytical approach to facilitate online continuous-flow isotope-ratio mass spectrometry (CF-IRMS) δD analyses of keratins through the use of calibrated keratin working standards and "comparative equilibration" to correct for the effects of moisture on exchangeable hydrogen.
Journal ArticleDOI
Linking breeding and wintering grounds of neotropical migrant songbirds using stable hydrogen isotopic analysis of feathers.
TL;DR: Hydrogen isotopes may become a powerful tool for linking breeding and wintering grounds of neotropical migrant songbirds, as well as other migratory species moving between isotopically distinct regions.
Journal ArticleDOI
Evaluation of the origin and fate of nitrate in the Abbotsford Aquifer using the isotopes of15N and18O in NO3
TL;DR: In this article, the authors found that NO3− contamination of groundwater in the Abbotsford aquifer to levels above drinking water limits is a major problem in the Fraser Lowlands of southwestern British Columbia, Canada.
Journal ArticleDOI
High-Precision Laser Spectroscopy D/H and 18O/16O Measurements of Microliter Natural Water Samples
TL;DR: A detailed assessment of the performance of a liquid-water isotope analyzer is presented, including instrument precision, estimates of sample memory and sample mass effects, and instrumental drift, and a recommended analysis procedure to achieve optimum results using OA-ICOS.
