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.

Paleoceanography and Paleoclimatology, Volume 41, Issue 8, August 2026.Abstract Greater ocean export productivity fueled by enhanced delivery of iron to the Sub‐Antarctic Zone (SAZ) of the Southern Ocean is hypothesized to play an important role in reducing atmospheric CO2 during Pleistocene glaciations. However, spatial variability in iron input and nutrient availability complicates quantifying the integrated impact of ...

Paleoceanography and Paleoclimatology, Volume 41, Issue 8, August 2026.Abstract The South Asian summer monsoon is a major component of the global climate system, yet its response to varying boundary conditions remains debated. We present pollen data from IODP Site U1446 (Bay of Bengal), recording vegetation changes in India's Core Monsoon Zone (CMZ) between 260 and 190 ka, spanning Marine Isotopic Stage (MIS) 7.

Understanding the hydrogeology and surface flow in the Cuatrociénegas Basin (NE Mexico) using stable isotopes [PDF]
, 2015 In this paper we present surface water oxygen (δ18O), hydrogen (δD) and inorganic carbon (δ13CDIC) isotope data to gain a better understanding of the modern day hydrogeology of Cuatrociénegas Basin, a semi-arid region in northeastern Mexico.

Preparation and Certification of Reference Materials for Hydrogen and Oxygen Isotopes in Water
Yankuang ceshi, 2013 Certified reference materials of water for stable hydrogen and oxygen isotopes were developed and have been used for more than 30 years. However, they no longer meet the requirements for newly developed technologies. New reference materials of water have

The Interpretability of Stable Hydrogen Isotopes in Modern Herbivore Tooth Enamel
, 2020 Stable hydrogen isotopes (δD values) in animal organic tissues such as collagen and keratin typically correlate with local meteoric water, but little is known about δD in tooth enamel apatite. In this study, we analyzed comminuted tooth enamel for oxygen
