该职业奖的教学和研究计划是从基础教育到前沿研究的连续体,每一步都涉及学生。一项新的教育举措旨在通过为高中全球变化科学教学开发新的网上教育资源,并将中学课堂与大学研究人员联系起来,扩大有才华的学生进入该领域的渠道。十年期气候变率研究将包括本科生和研究生的参与。课堂教学将涵盖全球变化的各个层面(从本科入门到高级研究生研讨会),采用多学科方法。研究部分的目的是确定热带印度洋和太平洋十年期变化的特征,并以新的结果为基础,这些结果表明,即使在这个时间尺度上,热带太平洋也发挥着主导和深远的作用。该项目利用长寿珊瑚骨骼中的多种地球化学示踪剂,将扩大中太平洋和西印度洋的变异记录。中太平洋的珊瑚记录清楚地记录了这一区域多个时间尺度的变率:它们提供了与仪器数据质量相当的厄尔尼诺/南方涛动的重建,它们揭示了与热带其他记录一致的十年变率。该项目将扩大以前的工作,从这一关键地区恢复较长的岩心,并通过开发多个示踪剂的重建,使盐度(降雨)和温度变化的分离。在西印度洋的额外取芯将在空间和时间上扩展该区域的方差记录,从而可以表征区域方差在多大程度上是由太平洋相对于更多的区域(例如季风)过程驱动的。
英文摘要
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.
