Description:

Abstract:

This data set consists of Globigerina bulloides Mg/Ca as a paleotemperature proxy. Indicated glacial-interglacial changes in sea surface temperature (SST) are about 4°C cooler in the Subantarctic Indian Ocean and 2.5°C cooler in the Subantarctic Pacific. Mg/Ca-based SST estimates and d18O determinations are then used to generate site-specific seawater d18O records. Data precision: Mg/Ca, ±2.1%; SST (est.), ±0.8°C; O18w (est.), ±0.2" G. bulloides O18 interpolated from Hays et al., 1976 and Imbrie et al., 1992, Mg/Ca data on cleaned G. bulloides shells by ICP-MS, SST estimates based on eq. (5) in Mashiotta et al., 1999, O18w calculated from bulloides O18 data, Mg/Ca-temperature estimates and Shackleton, 1974 paleo-temperature equation. chrono-strat info: SPECMAP age model from Imbrie et al, 1992 File E11-2.txt Core E11-2 56°04'S 115°05'W 3094m water depth Variables and units: Depth (cm), Age (ky), N. pachyderma (s) O18 (PDB), Mg/Ca (mmol/mol), SST (°C), O18w (SMOW) Data precision: Mg/Ca, ±2.1%; SST (est.), ±1°C; O18w (est.), ±0.2" N. pachyderma (s) O18 interpolated from Ninnemann and Charles, 1997, Mg/Ca data on cleaned N. pachyderma (s) shells by ICP-MS, SST estimates based on eq.
