The role of river runoff in the Kara Sea surface layer acidification and carbonate system changes

open access: yesEnvironmental Research Letters, 2019
This study aims to perform the results of the investigation of the Kara Sea carbonate system (CS) changes and the factors that determine it. The important feature of the Kara Sea water structure is strong stratification caused mainly by the Ob’ and ...

Synthesis of Aragonite from Precipitated Calcium Carbonate: A Pilot Scale Study

open access: yesIndonesian Journal of Chemistry
The CO2 mineralization pathway is considered a promising option for carbon capture usage and storage because the captured CO2 can be permanently stored, and secondly industrial waste (i.e., petrochemical refinery, lime, and cement kiln dust) can be ...

Identification of cave minerals by Raman spectroscopy: new technology for non-destructive analysis [PDF]

open access: yesInternational Journal of Speleology, 2006
The usual tools are X-ray powder diffraction, the optical microscope, and the scanning electron microscope. X-ray diffraction gives a definitive fingerprint by which the mineral can be identified by comparison with a catalog of reference patterns ...

Entering the Era of Directly Supporting Society With Observation‐Based Ocean Acidification Data

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Ocean acidification is a growing concern for many nations around the world. However, our capacity to monitor changes in carbonate chemistry with sufficient spatial and temporal resolution, has until now, been limited, which has impeded effective action and decision‐making at international, national, and regional levels.

Compound Hypoxia With Heat or Acidification Stress Induces Synergistic and Additive Effects on Coral Physiology

open access: yesGlobal Change Biology Communications, Volume 1, Issue 3, September 2026.
Multi‐stressor experiments on three coral species demonstrate hypoxia produces mostly additive effects with acidification but synergistically amplifies physiological stress under elevated temperatures. As global and local environmental change increase compound stress events on coral reefs, distinguishing hypoxia‐driven effects and interactive stressor ...

The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

open access: yesFisheries Oceanography, Volume 35, Issue 5, Page 689-703, September 2026.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

Stable Isotope–Enabled Particle Drift Models Predict Where High‐Resolution Isotope Analyses Can Discriminate Among Larval Trajectories in Atlantic Mackerel

open access: yesFisheries Oceanography, Volume 35, Issue 5, Page 760-776, September 2026.
ABSTRACT Marine fish commonly move across distinct habitats throughout their lifetimes, particularly during larval stages, when they are particularly difficult to track. Such transitions are necessary as environmental demands and predation pressures change dramatically with increases in body size.

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

open access: yesAdvanced Engineering Materials, Volume 28, Issue 15, 5 August 2026.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

Design of Hetero‐Core Fiber‐Optic SPR Sensor for Reliable Detection of Geothermal Scale Deposition

open access: yesAdvanced Sensor Research, Volume 5, Issue 8, August 2026.
A hetero‐core fiber‐optic SPR sensor provides rapid and reproducible monitoring of geothermal scale deposition. The mechanically robust design improves fabrication consistency and sensitivity compared with conventional sensors. Distinct peak shifts are observed for silica, carbonate, and sulfate scales, enabling fast, in situ evaluation of scale ...

Raman Line Scan Analyses and a New Hypothesis for the Formation of Anatase‐Hosting Microbialites: Study of the Stromatolites From Saint‐Jean‐de‐la‐Rivière, Cotentin, France

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 8, Page 1463-1480, August 2026.
Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms. ABSTRACT Raman
