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.

该奖项为智利复活节岛的气候变异性的多世纪和次年珊瑚时间序列的发展提供了资金。 复活节岛位于太平洋细胞的降肢下。一个显示明显衰减气候变异性的区域。 它也位于南太平洋Gyre的一部分，该部分充当南太平洋融合区大部分地区浅层子午线流的来源。 这些因素（合并在一起）被认为支持过去300年来从东南太平洋地区的海面温度的产生。研究旨在填补来自世界重要地区的数据的空白，可用于对气候，生态系统以及海面相互作用和反馈有更好的了解。 研究人员及其研究生将与智利大学和Concepcion大学的同事紧密合作，以解释发展中的复活节岛国数据集，并使智利学生能够在斯坦福大学参加交流访问。
