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.

该奖项提供资金，用于开发来自纽约北部阿迪朗达克地区湖泊沉积物核心的硅藻组合（具有玻璃壳的藻类）的连续高分辨率水文气候记录。 该研究的中心目的是阐明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）和全球到区域温度有关的性质和原因，并评估对降水趋势的相互冲突的气候模型预测。更广泛的影响包括对人口稠密的东北部区域降水模式和水资源可用性的理解的潜在改进，以及帮助澄清北大西洋涛动和温度对气候的影响。本科生将参加实地工作和沉积物岩心分析，这代表着为纽约州北部农村地区服务的学院学术环境的重要改善。 与区域利益相关者的合作将增强研究人员和学生获得研究设施、专业网络和专业知识的机会。研究结果将在科学会议上展示，并与学生合著者在同行评审期刊上发表。 研究产生的分析数据将存档在 NOAA 世界数据中心，物理沉积物样本将存档在女王大学和保罗·史密斯学院。
