Holocene records of foraminifera oxygen isotope and Mg/Ca-temperatures from MD98-2188
The Holocene variability in sea surface and thermocline water temperatures (SST and TWT) in the Indo-Pacific Warm Pool (IPWP) has been reconstructed by shell Mg/Ca of two planktonic foraminifera species, the mixed-layer dweller Globigerinoides ruber and the thermocline dweller Pulleniatina obliquilo...
