Advancing annually resolved oxygen isotope dendrochronology to overcome wood-dating limitations in the Euro-Atlantic region. [PDF]
Stable oxygen isotope dendrochronology has emerged as a ground-breaking technique for dating historic timbers when conventional tree-ring-width dendrochronology falls short.

Stable Isotope Analysis (δ<sup>13</sup>C, δ<sup>15</sup>N and δ<sup>18</sup>O) of Killer Whale Dentine: Evaluating Treatment Methods and Establishing Best Practices. [PDF]
ABSTRACT Rationale Stable isotope measurements in odontocete teeth can be used to reconstruct lifetime ecology, but some pre‐treatments may introduce bias. Isolating dentine collagen with HCl decalcification, removing the organic matrix or drying dentine prior to the analysis of structural carbonates can introduce unintended variability, limiting ...

Fish without water: Validation and application of δ18O in Totoaba macdonaldi otoliths
The geochemistry of fish otoliths is a valuable tool for reconstructing environmental conditions, migrations and life histories. In this study we validate the relationship between temperature, the water oxygen isotope composition (δ18O) and otolith δ18O

Effects of Pretreatment on the Isotopic Composition of Structural Carbonate in Ray‐Finned Fish Teeth [PDF]
ABSTRACT Rationale The carbon and oxygen stable isotope ratios (δ13C and δ18O) of carbonate contained in fish tooth dentin have the potential to offer insights into environmental and ecological conditions, making them promising targets for analysis in fossil specimens.

Tree-ring δ18O from an Alpine catchment reveals changes in glacier stream water inputs between 1980 and 2010 [PDF]
The tree-ring stable carbon and oxygen isotope chronologies from two forest sites located in the Forni Glacier forefield (Italy)—one along the glacier stream (GL) and the other toward the valley slope (SL)—were analyzed with the aim of disentangling the ...

Deer Antler δ<sup>18</sup>O Records Desalination in Israel's Water Supply. [PDF]
ABSTRACT Rationale Stable oxygen isotope ratios (δ¹⁸O) in mammalian tissues are widely used to reconstruct past climates, seasonal patterns, and animal origins. These analyses assume that animals drink local rainwater—an assumption now challenged by large‐scale anthropogenic water management.

The oxygen isotope composition of bivalve shells (δ18Oshell) can potentially record environmental variability of shallow lakes and therefore it has been extensively used as a proxy in the reconstruction of past climate and environmental conditions.

Constraining Holocene hydrological changes in the Carpathian–Balkan region using speleothem δ18O and pollen-based temperature reconstructions [PDF]
Here we present a speleothem isotope record (POM2) from Ascunsă Cave (Romania) that provides new data on past climate changes in the Carpathian–Balkan region from 8.2 ka until the present.

The origin of high δ18O zircons: marbles, megacrysts, and metamorphism [PDF]
The oxygen isotope ratios (δ18O) of most igneous zircons range from 5 to 8‰, with 99% of published values from 1345 rocks below 10‰. Metamorphic zircons from quartzite, metapelite, metabasite, and eclogite record δ18O values from 5 to 17‰, with 99% below
