Pacific Southwest United States Holocene Droughts and Pluvials Inferred From Sediment δ18O (calcite) and Grain Size Data (Lake Elsinore, California) [PDF]

, 2019
Records of past climate can inform us on the natural range and mechanisms of climate change. In the arid Pacific southwestern United States (PSW), which includes southern California, there exist a variety of Holocene records that can be used to infer ...

Fluorination of Silver Phosphate in Nickel Reaction Vessels for Triple Oxygen Isotope Analysis

Rapid Communications in Mass Spectrometry, Volume 40, Issue 7, 15 April 2026.
ABSTRACT Rationale Increasingly, more laboratories are measuring the triple oxygen isotope values of phosphate. Standardization is key to having good interlaboratory results. Here, we present the triple oxygen isotope values of a suite of standards using fluorination and compare them with previously reported triple oxygen isotope values. Methods Silver

Influence of stratiform clouds on δD and δ18O of monsoon water vapour and rain at two tropical coastal stations

Journal of Hydrology, 2018
Studies of moisture dynamics associated with major tropical rain activities with the aid of stable oxygen and hydrogen isotopic (δ18O and δD) measurements in precipitation and water vapour are of current research interest.

Applying rare earth elements, Uranium, and 87Sr/86Sr to disentangle structurally forced confluence of regional groundwater resources: The case of the Lower Yarmouk Gorge [PDF]

, 2019
The conjoint discussion of tectonic features, correlations of element concentrations, δ18O, δD, and 87Sr/86Sr of groundwater leads to new insight into sources of groundwater, their flow patterns, and salinization in the Yarmouk Basin.

Warming of the Mid‐Troposphere Driven by Evapotranspiration During Compound Heatwave and Drought Events

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract During compound heatwave and drought events (CHDE), a significant amount of soil moisture is released into the atmosphere through evapotranspiration. In this study, we used multi‐source atmospheric water vapor isotope data sets, including satellite and ground‐based observations, to investigate the role of evapotranspired water vapor (EWV ...

Indication of hydrogen and oxygen stable isotopes on the characteristics and circulation patterns of medium-low temperature geothermal resources in the Guanzhong Basin, China

Journal of Groundwater Science and Engineering, 2022
Guanzhong Basin is a typical medium-low temperature geothermal field mainly controlled by geo-pressure in the west of China. The characteristics of hydrogen and oxygen isotopes were used to analyze the flow and storage modes of geothermal resources in ...

North American transect of stable hydrogen and oxygen isotopes in water beetles from a museum collection [PDF]

, 2018
Museum collections contain a wealth of insect remains originating from a wide geographic range, which can be used to investigate their utility as a proxy for environmental isotope ratios.

Orbital and eustatic control of basin hydrology during the first stage of the Messinian Salinity Crisis

The Depositional Record, Volume 12, Issue 1, February 2026.
The paleo‐hydrology of the Sorbas Basin (SE Spain) and the wider Mediterranean region during the deposition of the Primary Lower Gypsum (PLG) stage of the Messinian Salinity Crisis, from ~5.97 to ~5.60 Ma, was affected by tectonics, precession‐forced climate oscillations, and eustatic sea‐level change.

Comparison between total least squares and ordinary least squares in obtaining the linear relationship between stable water isotopes

Geoscience Letters, 2022
The linear relationship between two stable water isotopes (δD and δ18O) has been used to examine the physical processes and movements or changes of three water phases (water vapor, liquid water and ice), including deuterium excess.

Northeast Siberian ice wedges confirm Arctic winter warming over the past two millennia [PDF]

, 2017
Arctic climate has experienced major changes over the past millennia that are not fully understood in terms of their controls and seasonality. Stable-data from ice wedges in permafrost provide unique information on past winter climate.
