Mg/Ca and d18O data for four species of planktic foraminifera (G. ruber (white), G. sacculifer (without sac), N. dutertrei, and P. obliquiloculata) from core top sediments from the tropical Pacific, Atlantic, and western Indian Ocean. Deepwater calcite saturation values (Delta[CO3**2-]) at the sites range from 55 to -23 µmol/kg. : XDX values are from Johnstone et al. (2010)./ small sample consisting of fewer than 15 tests# very small sample consisting of less than 5 tests (not used in regression)* duplicate sample (value not used in regression)
