- •
Analysis of Variance of stable isotopes of modern neritic foraminifera quantifies their reliability for Neogene studies.
- •
δ18O values of Orbulina universa and Uvigerina peregrina agreed with temperatures predicted from an equation.
- •
The approach requires screening for downslope transport with foraminiferal assemblages and referencing deep-sea core data.
- •
Oxygen isotopes of coeval benthic and planktic foraminifera can indicate shallow paleodepths and paleosalinity.
