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

该奖项提供资金，用于根据过去一千年纽约北部阿迪朗达克地区湖泊沉积岩心中的硅藻组合(具有玻璃壳的藻类)建立连续的高分辨率水文气候记录。这项研究的一个中心目的是澄清东北地区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)和全球至区域温度有关的事件，并评估相互矛盾的气候模式对降水趋势的预测。更广泛的影响包括潜在的改善对人口稠密的东北地区的区域降水模式和水资源供应的理解，以及帮助澄清NAO和温度对气候的影响。本科生将参与野外工作和沉积物岩心分析，这代表着一所为纽约州北部代表不足的农村地区服务的学院的学术环境得到了重要改善。与地区利益攸关方的合作将促进研究人员和学生获得研究设施、专业网络和专业知识。研究结果将在科学会议上公布，并与学生共同撰写同行评议期刊发表。这项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女王大学和保罗·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.
