This award funds the development of multi-century and sub-annual coral-based time series of climate variability from Easter Island, Chile. Easter Island is sited beneath the descending limb of the Pacific Cell; an area that shows pronounced decadal climate variability. It is also located with a section of the South Pacific Gyre that acts as a source for shallow subsurface meridional flow at the southeastern most section of the South Pacific Convergence Zone. These factors, when combined, are thought to support the production of time series of sea surface temperature over the past 300 years from the southeastern Pacific.The research aims to fill a gap for data from an important region of the world that can be used to develop a better understanding of climate, ecosystems, and sea surface interactions and feedbacks. The researchers and their graduate students will work closely with colleagues at the Universidad de Chile and the Universidad de Concepcion to interpret the developing Easter Island data set and to enable Chilean students to participate in exchange visits at Stanford University.

该奖项资助智利复活节岛基于珊瑚的气候变化的多世纪和亚年度时间序列的开发。 复活节岛位于太平洋细胞的下降分支下方；显示出明显的十年间气候变化的地区。 它还位于南太平洋环流的一部分，作为南太平洋辐合带最东南部浅层地下经向流的来源。 这些因素综合起来，被认为支持生成东南太平洋过去 300 年海面温度的时间序列。这项研究旨在填补世界重要地区数据的空白，这些数据可用于更好地了解气候、生态系统和海面相互作用和反馈。 研究人员及其研究生将与智利大学和康塞普西翁大学的同事密切合作，解释正在开发的复活节岛数据集，并使智利学生能够参加斯坦福大学的交流访问。
