Scientific Reports, 2023 Isotope-based records provide valuable information on past climate changes. However, it is not always trivial to disentangle past changes in the isotopic composition of precipitation from possible changes in evaporative enrichment, and seasonality may ...

Isotopic composition of oxygen and hydrogen of ice wedges in Central Yamal
Лëд и снег, 2021 New data on the distribution of the isotopes δ18О and δD of ice wedges in Central Yamal are presented. In the summer of 2019, the massive wedge ice was studied in the thermal circus of the third marine terrace.

Remarks on the deuterium excess in precipitation in cold regions [PDF]
Tellus B: Chemical and Physical Meteorology, 1991 Jouzel and Merlivat developed and used an expression for the kinetic fractionation coefficient α k , and greatly improved the predictions of δ ( 18 O) and d (the deuterium excess) for East Antarctica. The α k coefficient is re-derived in terms of ambient cloud temperatures and is used to re-calculate their single-source East Antarctic ...

A discussion of deuterium excess production in rain water
Shui kexue jinzhan, 2012 Study on the characteristic of hydrogen and oxygen isotopes in precipitation is an important aspect of water cycle research.However,the production process of deuterium excess(D-excess) in rain water has not been fully explained.From the perspective of ...

Vertical profile observations of water vapor deuterium excess in the lower troposphere [PDF]
Atmospheric Chemistry and Physics, 2019 We use airborne measurements of water vapor (H2Ov) stable isotopologues and complementary meteorological observations to examine how boundary layer (BL) dynamics, cloud processing, and atmospheric mixing influence the vertical structure of δD, δ18O, and ...

Deuterium excess in Greenland snow: Analysis with simple and complex models [PDF]
Journal of Geophysical Research: Atmospheres, 1998 A simple Rayleigh‐type isotope model, typical of those used to develop algorithms for extracting climatic information from stable water isotope paleodata, is evaluated against the more complex and presumably more reliable calculations of a general circulation model (GCM) fitted with isotope tracer diagnostics.
