Origin and residence time of groundwater based on stable and radioactive isotopes in the Heihe River Basin, northwestern China

Journal of Hydrology: Regional Studies, 2018
Study region: The Heihe River Basin (HRB) is one of several arid basins in which runoff from the Qilian Mountain recharges basin aquifers. Study focus: A basin-wide dataset (δ18O, D, 3H and 14C) is used to determine the present and past relationships ...

Recharge and Infiltration Mechanisms of Soil Water in the Floodplain Revealed by Water-Stable Isotopes in the Upper Yellow River

, 2021
The stable isotopes (δD and δ18O) in soil water allow tracing of the flow and transportation of water in the soil. However, there are few studies on the use of soil water stable isotopes to explore the soil water in the floodplain, especially in ...

Stable water isotopes of snow during MOSAiC expedition

, 2022
Snow samples were collected from several locations on the main MOSAiC ice floe on weekly basis. Snow samples for measurement of stable water isotopes (δ18O, δD,) were collected in three different layers (top, middle, bottom) using a metal density cutter.

Variable Response in Alpine Tree-Ring Stable Isotopes Following Volcanic Eruptions in the Tropics and Iceland

, 2022
The importance of the stable isotopes in tree rings for the study of the climate variations caused by volcanic eruptions is still unclear. We studied δ18O, δD, δ13C stable isotopes of larch and cembran pine cellulose around four major eruptions with ...

Alpine Holocene tree-ring dataset: age-related trends in the stable isotopes of cellulose show species-specific patterns [PDF]

, 2020
Stable isotopes in tree-ring cellulose are important tools for climatic reconstructions even though their interpretation could be challenging due to nonclimate signals, primarily those related to tree aging.
