在巴巴多斯近海钻探的珊瑚礁首次提供了最后一次冰消期海平面变化的连续和详细记录。在最后一次盛冰期，海平面比现在低121 ± 5米。冰消期的海平面上升不是单调的，而是以两个快速上升的间隔为标志。融化水排放到北大西洋表层海洋的速率变化极大地影响了北大西洋深水的生产和海洋氧同位素化学。根据巴巴多斯海平面曲线计算了全球海水氧同位素记录，从而可以分离深海岩心中测量的所有氧同位素记录所共有的冰体积部分。
Coral reefs drilled offshore of Barbados provide the first continuous and detailed record of sea level change during the last deglaciation. The sea level was 121 ± 5 metres below present level during the last glacial maximum. The deglacial sea level rise was not monotonic; rather, it was marked by two intervals of rapid rise. Varying rates of melt-water discharge to the North Atlantic surface ocean dramatically affected North Atlantic deep-water production and oceanic oxygen isotope chemistry. A global oxygen isotope record for ocean water has been calculated from the Barbados sea level curve, allowing separation of the ice volume component common to all oxygen isotope records measured in deep-sea cores.
