Our longstanding and successful research program on the biogeochemistry of watersheds focuses on important societal issues such as eutrophication, atmospheric deposition of contaminants, greenhouse gas emissions, drinking water security, wastewater disposal and climate change. Our specialized expertise is in the development and application of isotopic and non-isotopic tracers to provide information that cannot be gleaned from other methods. Fundamental to this endeavour is the quantitative analysis of the elements of life including nitrogen, oxygen and carbon. Here we request funding for an instrument that measures the important forms of these elements in gases dissolved in waters to gain critical information on nutrient cycling in soils, waters, wetlands and lakes in locations that range from pristine High Arctic watersheds to heavily urbanized settings. This instrument is at the heart of our analytical research laboratory and replaces a non-functioning, outdated and non-serviceable unit. The equipment will be heavily used by graduate and undergraduate students who are trained to analyze their own samples for their research on these environmental issues that are important to Canadian society.

我们在流域生物地球化学方面的长期成功研究项目侧重于重要的社会问题，如富营养化、大气污染物沉积、温室气体排放、饮用水安全、废水处理和气候变化。我们的专业知识是同位素和非同位素示踪剂的开发和应用，以提供无法从其他方法收集的信息。这项工作的基础是对包括氮、氧和碳在内的生命元素进行定量分析。在此，我们请求资助一种仪器，用于测量溶解在水中的气体中这些元素的重要形式，以获得从原始的高纬度北极流域到高度城市化环境中土壤、水、湿地和湖泊中营养循环的关键信息。该仪器是我们分析研究实验室的核心，取代了一个无功能，过时和不可用的单元。这些设备将被研究生和本科生大量使用，他们被训练来分析自己的样本，以研究这些对加拿大社会很重要的环境问题。
