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.

该职业奖的教学和研究计划是从基础教育到领先研究的连续性，每一步都涉及学生。一项新的教育计划旨在通过开发新的基于Web的教育资源来扩大进入该领域的才华横溢的渠道，用于全球变更科学的高中教学，并将中学教室与大学研究人员联系起来。关于际气候变异性的研究将纳入本科和研究生的参与。课堂教学将通过多学科的方法涵盖各级全球变化的各个方面（从入门本科到高级研究生研讨会）。该研究组成部分旨在表征热带印度和太平洋的十年变化，以新的结果为基础，这表明即使在这个时间范围内，热带太平洋也是热带太平洋的主导和深远的作用。该项目在长寿的珊瑚骨架中使用多个地球化学示踪剂，将扩大中太平洋中部和西印度洋的可变性记录。来自中太平洋中部的珊瑚记录清楚地记录了该地区的多个时间尺度：它们提供了ENSO的重建，它们的质量与仪器数据相当，并且揭示了与热带地区其他记录相一致的衰老变异性。该项目将通过从该关键区域中恢复更长的核心以及从多个示踪剂进行重建，从而扩展该项目，从而使盐度分离（降雨）和温度差异。印度洋西部的其他加油将在空间和时间上扩展该区域的差异记录，从而表征区域差异由太平洋与更具区域性（例如季风）过程驱动的程度。
