Stable isotope ratios of hydrogen and oxygen have been applied to water cycle research for
over 60 years. Over the past two decades, however, new data, data compilations, and …

Variations in speleothem oxygen-isotope values (δ18O) result from a complicated interplay
of environmental controls and processes in the ocean, atmosphere, soil zone, epikarst, and …

Isotope ratios of actively cycled elements vary as a function of the biogeochemical
processes in which they participate and the conditions under which those processes occur …

Isotope analysis has become an increasingly valuable tool in forensic anthropology
casework over the past decade. Modern-day isotopic investigations on human remains have …

We develop and test a model to predict the geographic region-of-origin of humans based on
the stable isotope composition of their scalp hair. This model incorporates exchangeable …

Methane is a key component in the global carbon cycle, with a wide range of anthropogenic
and natural sources. Although isotopic compositions of methane have traditionally aided …

The main elemental constituents (H, C, N, O, and S) of bio‐organic material have different
stable isotopes (2H, 1H; 13C, 12C; 15N, 14N; 18O, 17O, 16O; 36S, 34S, 33S, and 32S) …

Stable isotopes in water (δ 2 H and δ 18 O) are important indicators of hydrological and
ecological pattern and process. δ 2 H and δ 18 O of water are incorporated into geological …

Baseflow is essential for stream ecosystems and human water uses, particularly in areas
with Mediterranean climates. Yet the factors controlling the temporal and spatial variability of …

High-precision triple oxygen isotope analysis of waters is an emerging tool in hydrological
and paleoclimate research. The existing research on 17 O-excess in waters includes …
