Passive CO2 removal in urban soils:evidence from brownfield sites [PDF]
, 2020 Management of urban brownfield land can contribute to significant removal of atmospheric CO2 through the development of soil carbonate minerals. However, the potential magnitude and stability of this carbon sink is poorly quantified as previous studies ...

The origin of carbon isotope vital effects in coccolith calcite
Nature Communications, 2017 Calcite microfossils are widely used to study climate and oceanography in Earth’s geological past. Coccoliths, readily preserved calcite plates produced by a group of single-celled surface-ocean dwelling algae called coccolithophores, have formed a ...

Geochemistry, Geophysics, GeosystemsPast ocean conditions are often reconstructed using the elemental composition of foraminiferal calcite. However, foraminiferal remains are often impacted by post‐depositional contaminants; thus, they require cleaning prior to element/Ca (El/Ca) analysis.

Marine bivalve geochemistry and shell ultrastructure from modern low pH environments [PDF]
, 2011 . Bivalve shells can provide excellent archives of past environmental change but have not been used to interpret ocean acidification events. We investigated carbon, oxygen and trace element records from different shell layers in the mussels Mytilus ...
