A detailed stable isotope study based on benthic foraminifera from 1165 samples from ODP Site 1148 (18 degrees 50.17.3'N, 116 degrees 33.93'E, water depth 3308.3 m) in the northern South China Sea provides an excellent oxygen isotopic record with an average resolution of 30 ka. It contains the most continuous delta (super 18) O data with the highest resolution for the whole Neogene sequence in the world. The delta (super 18) O curve shows a step-like increase and records 5 increases, 3 decreases and 2 stable stages during the Neogene, reflecting the general trend of global cooling. Among these events, the delta (super 18) O decrease at 17.2-14.5 Ma and two delta (super 18) O increases at 14.5-13.6 and 3.0-2.4 Ma are the most marked and the most globally comparable. The intervals at 13.6-10.2 and 6.0-3.0 Ma with the lowest amplitude and least fluctuation in delta (super 18) O represent the most stable periods for bottom water in the South China Sea.
