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

CAREER奖的教学和研究项目是一个从基础教育到前沿研究的连续统一体，涉及学生的每一步。一项新的教育计划旨在通过开发一种新的基于网络的全球变化科学高中教学教育资源，并将中学教室与大学研究人员联系起来，从而扩大有才能的学生进入该领域的渠道。年代际气候变率的研究将包括本科生和研究生的参与。课堂教学将以多学科的方式涵盖全球变化的各个方面（从本科入门到高级研究生研讨会）。研究部分旨在描述热带印度洋和太平洋的年代际变化特征，其基础是新的结果，这些结果表明，即使在这个时间尺度上，热带太平洋也具有主导和深远的作用。该项目利用多种地球化学示踪剂在长寿珊瑚骨架中进行研究，将扩大太平洋中部和印度洋西部变化的记录。来自中太平洋的珊瑚记录清楚地记录了该地区的多个时间尺度的变化：它们提供了与仪器数据质量相当的ENSO重建，它们揭示了与热带地区其他记录一致的年代际变化。该项目将扩展之前的工作，从该关键区域恢复更长的岩心，并通过多种示踪剂进行重建，从而分离盐度（降雨）和温度变化。西印度洋的额外取芯将扩展该区域的时空差异记录，从而可以表征太平洋与更区域性（如季风）过程驱动的区域差异程度。

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.
