Reconstruction of the Eustatic Sea Level Curve 15,000 to 5,000 Years Before Present

该项目包括一个实地方案，在巴巴多斯的侧翼取钻芯，以恢复在最近海平面上升期间沉积的珊瑚样本。研究中使用的珊瑚品种只生长在海平面5米以内。通过准确地确定发现珊瑚的年龄和发现珊瑚的深度，将构建过去15000年的海平面曲线。这条海平面曲线将是最近海平面上升的第一个精确曲线，据估计，自上一个冰河期以来，海平面上升了75至160米。研究结果将应用于古海洋学中一个长期存在的问题：如何根据深海岩心的氧同位素信号将冰体积（海平面）与温度分离开来。一旦确定了海平面上升的幅度和时间，就可以从同位素记录中提取温度信号。

The project involves a field program to take drill cores on the flank of Barbados in order to recover coral samples deposited during the most recent rise of sealevel. The coral species to be used in the study only grows within 5 meters of sealevel. By accurately determining the age of the coral recovered and the depth where it is found, a sealevel curve for the last 15,000 years will be constructed. This sealevel curve will be the first accurate curve of the most recent sealevel rise which has been estimated to be from 75 to 160 meters since the last ice age. The results will applied to a long-standing problem in paleoceanography: how to separate ice volume (sealevel) from temperature on the oxygen isotope signal in deep sea cores. Once the magnitude and timing of the sealevel rise is solved, the temperature signal may be extracted from isotope records.
