Quantifying recycled moisture fraction in precipitation of an arid region using deuterium excess [PDF]

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2013
Terrestrial moisture recycling by evapotranspiration has recently been recognised as an important source of precipitation that can be characterised by its isotopic composition.

Ice‐age variability from the Vostok deuterium and deuterium excess records [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2001
The four climatic cycles obtained from the Vostok ice core offer a unique opportunity to study the high‐frequency paleoclimatic variability, i.e., on time scales smaller than 15 kyr. We focused our study on the deuterium (δD) and deuterium excess (d) records, which are proxies for local temperature and remote evaporation source temperature and hence ...

Precipitation regime and stable isotopes at Dome Fuji, East Antarctica [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
A unique set of 1-year precipitation and stable water isotope measurements from the Japanese Antarctic station, Dome Fuji, has been used to study the impact of the synoptic situation and the precipitation origin on the isotopic composition of ...

The Global Stratotype Section and Point (GSSP) for the base of the Holocene Series/Epoch (Quaternary System/Period) in the NGRIP ice core [PDF]

open access: yes, 2008
The Greenland ice core from NorthGRIP (NGRIP) contains a proxy climate record across the Pleistocene– Holocene boundary of unprecedented clarity and resolution.

Lagrangian process attribution of isotopic variations in near-surface water vapour in a 30-year regional climate simulation over Europe [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
Stable water isotopes are naturally available tracers of moisture in the atmosphere. Due to isotopic fractionation, they record information about condensation and evaporation processes during the transport of air parcels, and therefore present a ...

Water tagging experiments for the interpretation of deuterium excess in Antarctica

open access: yes, 2021
These simulation results are from the water-tagging experiments in the manuscript "Sublimation origin of negative deuterium excess observed in snow and ice samples from McMurdo Dry Valleys and Allan Hills Blue Ice Areas, East Antarctica" submitted to the

Atmospheric influence on the deuterium excess signal in polar firn: implications for ice core interpretation [PDF]

open access: yes, 2008
The seasonal deuterium excess signal of fresh snow samples from Neumayer station, coastal Dronning Maud Land, Antarctica, was studied to investigate the relationship between deuterium excess and precipitation origin.

Spatial distribution and interannual trends of δ18O, δ2H, and deuterium excess in precipitation across North-Eastern Italy [PDF]

open access: yes, 2021
NE Italy presents high-quantity, high-quality and easily exploitable groundwater resources that are seriously threatened by anthropogenic pressures. This study analyzes the oxygen and hydrogen isotopic composition of 2250 precipitation samples collected ...

Resolving the controls of water vapour isotopes in the Atlantic sector

open access: yesNature Communications, 2019
Water isotope modelling is an important tool in climate reconstructions, but there remain gaps in our understanding of the effects upon oxygen and hydrogen isotope fractionation, and thus the source of the deposited signal.

Direct depth distribution measurement of deuterium in bulk tungsten exposed to high-flux plasma

open access: yesAIP Advances, 2017
Understanding tritium retention and permeation in plasma-facing components is critical for fusion safety and fuel cycle control. Glow discharge optical emission spectroscopy (GD-OES) is shown to be an effective tool to reveal the depth profile of ...
