A High-Resolution Sea-Surface Temperature Record from the Tropical South China Sea (16,500–3000 yr B.P.)
Abstract The timing and magnitude of sea-surface temperature (SST) changes in the tropical southern South China Sea (SCS) during the last 16,500 years have been reconstructed on a high-resolution, 14 C-dated sediment core using three different foraminiferal transfer functions (SIMMAX28, RAM, FP-12E)...
