CAREER: Decadal Variability in the Tropical Pacific and Indian Oceans -An Interdisciplinary Pathway for Global Change Education and Research

这一职业奖项的教学和研究计划是从基础教育到前沿研究的连续统一体，让学生参与到每一步。一项新的教育倡议旨在通过为高中全球变化科学教学开发一个新的网络教育资源，并将中学课堂与大学研究人员联系起来，扩大进入该领域的有才华的学生的渠道。十年气候变化的研究将包括本科生和研究生的参与。课堂教学将采用多学科方法，涵盖全球变化各个层面的各个层面(从本科生入门到高级研究生研讨会)。这一研究构成部分旨在以新的结果为基础，确定热带印度洋和太平洋的年代际变化特征，这些结果表明，即使在这个时间尺度上，热带太平洋仍发挥着重要和深远的作用。利用长寿珊瑚骨架中的多种地球化学示踪剂，该项目将扩大中太平洋和西印度洋的可变性记录。来自中太平洋的珊瑚记录清楚地记录了该区域变化的多个时间尺度：它们提供了质量与仪器数据相当的ENSO的重建，它们揭示了与热带其他记录相一致的年代际变化。该项目将扩大以前的工作，从这一关键区域恢复更长的岩心，并利用能够分离盐度(降雨量)和温度变化的多个示踪剂进行重建。西印度洋的额外取芯将在空间和时间上扩大该区域的变化记录，从而能够描述太平洋相对于更多的区域性(例如季风)过程在多大程度上推动区域变化。

The teaching and research program for this CAREER award is a continuum from basic education through leading-edge research, involving students at every step. A new educational initiative aims to expand the pipeline of talented students entering the field by developing a new web-based educational resource for high-school teaching of global change science and linking secondary school classrooms with university researchers. Research on decadal climate variability will incorporate undergraduate and graduate participation. Classroom teaching will cover diverse aspects of global change at all levels (from introductory undergraduate through advanced graduate seminars) with a multidisciplinary approach. The research component aims to characterize decadal variability in the tropical Indian and Pacific Ocean, building on new results that indicate a dominant and far-reaching role for the tropical Pacific even at this time scale. Using multiple geochemical tracers in long-lived coral skeletons, this project will expand the record of variability in the central Pacific and western Indian Oceans. Coral records from the central Pacific clearly record the multiple time scales of variability in this region: they offer reconstructions of ENSO that are comparable in quality to instrumental data, and they reveal decadal variability that is coherent with other records in the tropics. This project will expand on previous work by recovering longer cores from this key region and by developing reconstructions from multiple tracers that allow the separation of salinity (rainfall) and temperature variance. Additional coring in the western Indian Ocean will extend the record of variance in that region both spatially and temporally, allowing characterization of the extent to which regional variance is driven by Pacific versus more regional (e.g. monsoonal) processes.
