文摘
- •
A sensitive Mg/Ca paleothermometer for deep-sea temperature reconstruction is presented.
- •
Concentration of ΔCO2−3 in porewater is spatially and temporally variable.
- •
ΔCO2−3 pore water is highly correlated to the ΔCO2−3 of the overlying bottom water.
- •
Mg/Ca (Globobulimina) sensitivity to ΔCO2−3 is estimated 0.009 mmol/mol/μmol/kg.
