Multicentury Reconstruction of Tropical Climate Variability from Red Sea Corals

有了这个奖项，研究人员的目标是开发大约400年前红海中部的海表面温度和盐度记录。这些记录将使用珊瑚骨架中的微量元素和氧同位素产生，并将在长钻芯中以双周、季节性和年度分辨率进行测量。红海地区的海温和盐度对北大西洋涛动(NAO)的气候强迫高度敏感。该项目的目标是揭示NAO的长期变化，并确定NAO的行为模式是否在持续的平均气候温暖和寒冷时期发生变化。更广泛的影响涉及对一名女性博士生和一名女性少数民族本科生的培训和教育。确定NAO行为和平均气候之间的关系也将是在未来全球变暖的情况下提高我们预测NAO行为的能力的重要一步。

With this award, researchers aim to develop sea surface temperature and salinity records from the central Red Sea back ~400 years. The records will be generated using trace element and oxygen isotopes in coral skeletons, and will be measured in long drill cores at bi-weekly, seasonal and annual resolution. Both sea surface temperature and salinity in the Red Sea region are highly sensitive to climate forcing from the North Atlantic Oscillation (NAO). The goal of this project is to reveal long-term changes in the NAO, and determine whether patterns of NAO behavior changed during periods of sustained warm and cold mean climate. The broader impacts involve the training and education of a female Ph.D. student and a female minority undergraduate student. Identifying a relationship between NAO behavior and mean climate would also be a substantial step toward improving our ability to predict NAO behavior in the face of future global warming.
