David Evans and the ‘Amoeba’ Lab at the University of Southampton (UK), researching (foraminifera) biomineralisation and climate change in Earth’s past

A graph showing that changes in the rate of sea floor spreading and the concentration of calcium in seawater are qualitatively similar over the Cenozoic.
A multi-panel figure presenting a carbon cycle box model driven by changes in the silicate weathering rate and the concentration of calcium in seawater. Both processes may result in large CO2 changes, depending on how silicate weathering is parameterised in the model.
A graph showing that the concentration of calcium in seawater and the concentration of CO2 in the atmosphere were closely correlated over the Cenozoic

The quality of multivariate benthic foraminifera temperature and saturation state calibrations assessed via inverse prediction intervals.
A compilation of benthic foraminifera trace element data plotted against temperature, saturation state, and DIC concentration.
