项目摘要

Swart/Hollander 0823636/0823268This award will provide funds to obtain new proxy records of the Atlantic Multidecadal Oscillation (AMO) over time periods between 100 to 1000 years using sclerosponge aragonite geochemistry (18O/16O and Sr/Ca), and to investigate possible artifacts in stable oxygen and carbon (13C/12C) isotope data due to alteration during the sampling of aragonitic skeletal material. Specific objectives include 1) the generation of sclerosponge geochemical data, combined with improved dating, to confirm a correlative link between salinity and AMO at multiple locations in the Bahamas and Caribbean both prior to and after the instrumental record (~1850), 2) improvement of the geochemical calibrations between temperature and Sr/Ca and d18O based on a new collection of ~ 24 sclerosponge specimens collected between 1986 and 1996 and 3) investigation of additional minor and trace elements as recorders of environmental conditions in the tropical subsurface environment. The Broader Impacts include the societal relevance of research directed at understanding a fundamental question of the climate system that could have a synergistic impact on human-contributed forcings of the climate system and support of research by undergraduate and graduate students.
该奖励将提供资金,用于利用硬海绵文石地球化学(18O/16O和Sr/Ca)获得100至1000年间大西洋多年代用振荡(AMO)的新代理记录,并研究稳定氧和碳(13C/12C)同位素数据中由于文石骨骼材料采样期间的变化而可能产生的人工制品。具体目标包括:1)生成硬化剂海绵地球化学数据,结合改进的年代测定,以确认在仪器记录之前和之后(~1850)巴哈马和加勒比多个地点的盐度与AMO之间的相关联系;(2)基于1986 ~ 1996年新采集的~ 24个海绵标本,改进了温度与Sr/Ca和d18O的地球化学校准;(3)研究了热带地下环境中附加的微量元素和痕量元素作为环境条件的记录。更广泛的影响包括旨在理解气候系统基本问题的研究的社会相关性,这些问题可能对气候系统的人为强迫产生协同影响,并支持本科生和研究生的研究。
