Studies involving dissolved conservative gases in groundwater have usually found a gas
excess above atmospheric solubility equilibrium (excess air), but sometimes also gas …

To establish the increase in temperature and the time span of the transition between the
Late Glacial Maximum (LGM) and the Holocene, the noble gas content, 18O, 2H, 13C δ …

Speleothems are increasingly used as an archive of past climate, but some of the proxy
signals encoded in these deposits reflect hydrological characteristics of the karst aquifer …

Multiple age tracers were measured to estimate groundwater residence times in the regional
aquifer system underlying southwestern Oman. This area, known as the Najd, is one of the …

This paper describes the procedure followed for noble gas measurements for litres, millilitres
and microlitres of water samples in our laboratory, including sample preparation, mass …

Abstract In Canadas western Arctic, perennial discharge from permafrost watersheds is the
surface manifestation of active groundwater ow systems with features including the …

Noble gas concentrations in natural waters are widely used to determine ambient
temperature conditions during the last intensive contact with the atmosphere (equilibration) …

Perennially flowing groundwater discharges along a 15‐km section of the Fishing Branch
River, Yukon causing open water during winter and numerous discrete springs near Bear …

Soil air composition is known to fluctuate both temporally and spatially. These fluctuations
are mainly caused by microbiological activity, leading to oxygen depletion. The exact …

Field and laboratory investigations were performed to identify the principal mechanisms of
the hydrochemical groundwater evolution among low mineralised groundwater in the …
