MRI: Acquisition of Major Instrumentation for Watershed Biogeochemistry Research

这一重大研究仪器(MRI)计划赠款的资金用于购买多种仪器，用于流域生物地球化学研究和瓦萨学院的研究培训。将购置的具体仪器包括一个离子色谱仪、两个多参数探测仪(黄泉仪器)，用于对水温、盐度、溶解氧和营养物浓度进行时间采样，以及四个水位监测设备。瓦萨学院是一所本科院校，最初是一所女子学院，但自1969年以来一直是男女同校。该设备将支持教师和学生对溪流生物地球化学循环的研究，重点是城市化地区受人类活动影响的系统。例如，研究了发展对河流养分收支和养分储存的影响；土壤和地下水中除冰盐的运输、储存和去向；以及污染物在大气沉积和生物积累方面的长期变化。这一工具将进一步推动瓦萨学院致力于让本科生，包括女性和少数族裔，参与教师指导的研究。该仪器将被整合到多个部门的许多现有课程中。拟议的工具套件针对当地环境问题，PI参与了学院的卡斯珀基尔研究倡议(CRI)，该倡议横跨科学和社会科学，让学生参与暑期研究体验，与当地非营利组织合作，并与公共和地方治理部门进行外联。

Funding from this Major Research Instrumentation (MRI) Program grant supports acquisition of multiple instruments for watershed biogeochemical research and research training at Vassar College. Specific instruments to be acquired include an ion chromatograph, two multi-parameter sondes (Yellow Springs Instruments) for temporal sampling of water temperature, salinity, dissolved oxygen and nutrient concentrations, and four water level monitoring devices. Vassar College is an undergraduate institution originally founded as a women's college though it has been co-educational since 1969. The equipment will support faculty and student research on stream biogeochemical cycling with a focus on anthropogenically impacted systems in urbanized areas. Examples include studies of the impacts of development on in-stream nutrient budgets and nutrient storage; transport, storage, and fate of deicing salts in soils and groundwater; and long-term changes in atmospheric deposition and biotic accumulation of contaminants. The instrumentation will further Vassar College's commitment to involving undergraduate students, including women and minorities, in faculty-mentored research. The instrumentation would be integrated into numerous existing courses across multiple departments. The proposed suite of instrumentation targets local environmental issues and the PI's are engaged in the College's Casperkill Research Initiative (CRI) that spans the sciences and social sciences, engages student in summer research experiences, partners with local non-profits, and conducts outreach to the public and local governance sectors.
