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.

有了这个奖项，研究人员的目标是开发海面温度和盐度记录，从中央红海返回约400年。 这些记录将使用核心骨骼中的痕量元素和氧同位素生成，并以每两周的季节性和年度分辨率在长钻芯中测量。红海地区的海面温度和盐度都对从北大西洋振荡（NAO）强迫的气候强度高度敏感。 该项目的目的是揭示NAO的长期变化，并确定NAO行为的模式是否在持续的温暖和冷平均气候期间发生变化。更广泛的影响涉及对女性博士学位的培训和教育。学生和女性少数族裔本科生。 确定NAO行为与平均气候之间的关系也将是提高我们在未来全球变暖时预测NAO行为的能力的重要一步。
