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

Environmental 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

Indonesian 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]

International 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

Perspectives 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.

The role of sulfate in the hydrothermal replacement of aragonite single crystals by calcite

Aragonite (CaCO3) is a stable calcium carbonate phase under high pressure conditions. However, its formation in (sub)surface environments, where calcite is the stable polymorph, is widespread.

O in biogenic aragonite

, 2008
Extraction of small aliquots ( mu g- mg) from aragonite samples such as corals, sclerosponges, bivalves, and otoliths is required for bulk oxygen isotope analyses.

Climate Vulnerability of Australian Seafood Systems: A National Assessment of Exposure and Adaptive Capacity

Fisheries Oceanography, Volume 35, Issue 6, Page 849-864, November 2026.
ABSTRACT Marine waters are becoming warmer and acidified and experiencing more intense and longer heatwaves under climate change. These changes are already impacting marine ecosystems and seafood production, which are vital for supporting food security and economic productivity.

Climate Change Induced Seasonal Amplification of the Indian Ocean CO2 Sink

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract This study investigates changes in the mean and seasonal states of oceanic carbon uptake across the Indian Ocean (IO) using an improved, high‐resolution, observationally constrained long‐term (1980–2019) surface ocean pCO2 ${\text{pCO}}_{2}$ data product.
