This project will fund a full-time technician for three years in the Biogeochemistry Laboratory at the University at Buffalo. The principal investigator is an early-career geoscientist who will conduct research focused on understanding mechanisms of changes in water availability related to climate variability. The laboratory reconstructs past climate by examining sediments that record minute geochemical signatures of past environmental conditions. The studies will be conducted on samples from all around the world, including temperate regions, where large populations and food production occur, and the Arctic system, where sea ice loss will affect precipitation and in turn affect ice sheets and sea level rise. The research results have important societal implications for planning for droughts, floods, extreme storm events, and ice sheet mass loss. The project will enhance the principal investigator's partnership with the Buffalo Audubon Society for education and outreach, which includes a citizen-scientist program activity for the collection of weekly sediment and precipitation samples.The funding of a full-time technician at the University at Buffalo for three years will immediately increase the research productivity of an early-career geoscientist and establish the basis for long-term support for the position. The technician will be employed in the principal investigator's Organic and Stable Isotope Biogeochemistry Laboratory, which contains state-of-the-art equipment for sample extraction, preparation, and analysis at high spatial and temporal resolution. The laboratory's research goal is to provide prehistorical context for and mechanistic understanding of water-related changes associated with climate change. Potentially harmful consequences, such as droughts, floods, extreme storm events, and ice sheet mass loss, are of high societal and environmental significance, as they affect ecosystem stability, hydroelectric and agricultural production, and ice sheets and sea level rise. The increased research capacity of the laboratory enables more activities in the education and outreach partnership with the Buffalo Audubon Society, which includes teaching diverse groups about the glacial and climate history of New York, involving school-age summer camp groups in sample collection, participating in career days that expose young adults to a broad range of environmental careers, and analyzing samples from a citizen-science program.

该项目将资助一名全职技术人员在布法罗大学生物地球化学实验室工作三年。首席研究员是一位职业生涯早期的地球科学家，他将进行的研究重点是了解与气候变化相关的可用水量变化的机制。该实验室通过检查记录过去环境条件的微小地球化学特征的沉积物来重建过去的气候。这些研究将对来自世界各地的样本进行，包括人口众多和粮食生产较多的温带地区，以及海冰损失将影响降水并进而影响冰盖和海平面上升的北极系统。研究结果对于干旱、洪水、极端风暴事件和冰盖质量损失的规划具有重要的社会影响。 该项目将加强首席研究员与布法罗奥杜邦协会在教育和推广方面的合作伙伴关系，其中包括每周收集沉积物和降水样本的公民科学家计划活动。三年将立即提高职业生涯早期地球科学家的研究生产力，并为该职位的长期支持奠定基础。该技术人员将受聘于首席研究员的有机和稳定同位素生物地球化学实验室，该实验室拥有最先进的设备，用于高空间和时间分辨率的样品提取、制备和分析。该实验室的研究目标是为与气候变化相关的水变化提供史前背景和机制理解。潜在的有害后果，如干旱、洪水、极端风暴事件和冰盖质量损失，具有很高的社会和环境意义，因为它们影响生态系统的稳定性、水力发电和农业生产以及冰盖和海平面上升。实验室研究能力的增强使得能够与布法罗奥杜邦协会开展更多的教育和外展合作活动，其中包括向不同群体教授纽约的冰川和气候历史、让学龄夏令营团体参与样本收集、参与让年轻人接触广泛的环境职业的职业日，并分析公民科学项目的样本。
