Comparisons of strontium isotope ratios in the water and otoliths suggest narrow habitat ranges of freshwater three-spined sticklebacks in Otsuchi, Japan

open access: yesProgress in Earth and Planetary Science
Stable isotope analysis is useful in elucidating the flow of elements among organisms and environments. Understanding the movement of organisms is important for the conservation of ecosystems, and radiogenic strontium stable isotope ratios (⁸⁷Sr/⁸⁶Sr ...

The Giant Pacific Oyster (Crassostrea gigas) as a modern analog for fossil ostreoids: Isotopic (Ca, O, C) and elemental (Mg/Ca, Sr/Ca, Mn/Ca) proxies

open access: yesGeochemistry, Geophysics, Geosystems, 2013
Modern analogs are an essential part of palaeoclimate studies, because they provide the basis for the understanding of geochemical signatures of fossils.

Multifaceted orogenic fluid dynamics unraveled by hydrothermal epidote [PDF]

open access: yesEuropean Journal of Mineralogy
Characterizing fluid circulation in orogens is key to understanding orogenic processes because fluid–rock interaction modifies the physical properties of rocks, hence their response to deformation and, for example, their suitability for radioactive waste

Ultraspectral UV polychromator for SRS-isotopic sensor

open access: yesJournal of Physics: Conference Series, 2019
Abstract We have developed a spectral module for the selection of narrow characteristic spectral lines of isotopes in the ultraviolet Raman spectral channel. To allow resolving closely spaced isotope lines in the continuous input radiation spectrum, extremely high resolution λ / Δλ = 1000 is implemented.

Fractionation Mechanism and Flux Estimation of Strontium Isotopes During Basalt Weathering

open access: yesGeochemistry, Geophysics, Geosystems
The fluxes of metal cations and isotopes released by weathering of silicate rocks are crucial and a prerequisite for constraining geochemical fluxes to rivers and oceans.

Delineating population structure of resilient sea/river‐type sockeye salmon

open access: yesLimnology and Oceanography Letters
Conserving wild fisheries requires identifying and monitoring distinct populations, yet prevalent genetic approaches often do not integrate habitat data and may not fully delineate these structures. This issue is critical in sea/river‐type sockeye salmon
