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.

该奖项提供了资金，以在上一千年中，在纽约北部阿迪朗达克地区的湖泊沉积物核心中，从硅藻组合（带有玻璃壳的藻类）开发连续的高分辨率水力气候记录。 这项研究的主要目的是阐明东北降水可变性和极端事件的性质和原因，尤其是与北大西洋振荡（NAO）（NAO）和全球与区域温度有关的关系，并评估降水的气候模型预测趋势的冲突气候模型的预测趋势。在北部的降水范围内涉及更广泛的危险影响，涉及北部的潜在危险范围，使北部的降水范围和北方的固定范围越来越明确，并阐明了越来越明显的范围。本科生将参加野外工作和沉积物核心分析，这代表了一所学院的重要增强，该学院为纽约州北部地区代表不足的农村地区提供服务。 与区域利益相关者的合作将增强研究设施，专业网络以及研究和学生的专业知识的访问。研究的结果将在科学会议上介绍，并与学生共同作者发表在同行评审的期刊上。 该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·史密斯学院归档。
