RUI: High-Resolution Lacustrine Records of Precipitation Variability in the Northeastern United States during the Last Millennium

该奖项提供资金，从北方纽约阿迪朗达克地区的湖泊沉积物岩心中的硅藻组合（有玻璃壳的藻类）中，在过去的一千年里开发连续的高分辨率水文气候记录。 研究的一个中心目标是澄清东北部降水变化和极端事件的性质和原因，特别是与北大西洋涛动（NAO）和全球到区域温度的关系，更广泛的影响包括可能改善对人口稠密的东北部地区区域降水模式和水资源可用性的理解，阐明北大西洋涛动和气温对气候的影响。本科生将参加实地工作和沉积物岩心分析，代表了一个大学，服务于一个代表性不足的纽约北部农村地区的学术环境的重要增强。 与区域利益相关者的合作将增加研究机构、专业网络和专业知识的使用，研究成果将在科学会议上发表，并与学生合著者一起发表在同行评审的期刊上。 研究产生的分析数据将在NOAA世界数据中心存档，物理沉积物样本将在皇后大学和保罗史密斯学院存档。

The award provides funds to develop continuous high-resolution hydro-climate records from diatom assemblages (algae with glassy shells), over the last millennium, in lake sediment cores from the Adirondack region of northern New York. A central aim of the research is to clarify the nature and causes of northeastern precipitation variability and extreme events, particularly in relation to the North Atlantic Oscillation (NAO) and global to regional temperatures, and to evaluate conflicting climate model projections of precipitation trends.The broader impacts involve potential improvements in understanding regional precipitation patterns and water availability in the populous northeast as well as helping to clarify the influences of the NAO and temperature on climate. Undergraduate students will participate in field work and sediment core analyses, representing an important enhancement of the academic environment at a college that serves an under-represented rural region of upstate New York. Collaborations with regional stakeholders will enhance access to research facilities, professional networks, and expertise for both the research and students.Results of the research will be presented at science conferences and published in peer-reviewed journals with student co-authors. The analytical data resulting from the research will be archived at the NOAA World Data Center and physical sediment samples will be archived at Queen's University and Paul Smith's College.
