The project aims at the development of an improved understanding of how human-induced changes in Arctic freshwater ecosystems, such as climate change and resource development, may impact the health of northern freshwater resources and the provision of ecosystem services such as sustainable fisheries. The work will establish baseline studies of the structure, function and diversity of the Lake Greiner watershed, Victoria Island Nunavut, from its lowest trophic levels (micros, algae, plankton) to its upper trophic levels (fish) to describe how the functioning and structure of aquatic ecosystems support the production of juvenile fishes and the diversity other resident organisms and the habitats upon which the health and sustainability of fisheries ultimately depend. The work will involve a multi-disciplinary team of researchers from across the country and will expand beyond simple study of lake ecosystems to include landscape level attributes of the watershed such as tributary streams that serve as important rearing and connectivity habitats for fish. The work will establish and validate monitoring protocols for aquatic ecosystems in the north, thereby providing tools to government agencies for the continued routine monitoring of the systems and a means by which the significance of the accumulation of future ecosystem impacts (e.g., climate change, resource development) may be determined. The work will incorporate local ecological knowledge to connect northerners to the discipline of scientific assessment and provide them with the necessary access to the science need to aid them in the local management of aquatic resources. Finally the research work will link Canadian science to the larger international set of initiatives aimed at improving understanding of Arctic aquatic ecosystems at a global scale, thereby helping to enhance Canada's reputation for Arctic science.

该项目旨在更好地了解北极淡水生态系统中人类引起的变化，如气候变化和资源开发，如何影响北方淡水资源的健康和生态系统服务的提供，如可持续渔业。这项工作将从最低营养水平开始，对维多利亚岛努纳武特的格雷纳湖流域的结构、功能和多样性进行基线研究（微生物，藻类，浮游生物）向其上层营养水平（鱼类）描述水生生态系统的功能和结构如何支持幼鱼的生产，以及渔业健康和可持续性所依赖的其他常驻生物和生境的多样性最终取决于。这项工作将涉及来自全国各地的多学科研究人员团队，并将扩展到湖泊生态系统的简单研究之外，包括流域的景观水平属性，例如作为鱼类重要饲养和连接栖息地的支流。这项工作将建立和验证北部水生生态系统的监测协议，从而为政府机构提供工具，继续对系统进行例行监测，并提供一种手段，用以评估未来生态系统影响的累积的重要性（例如，气候变化、资源开发）。这项工作将纳入当地生态知识，使北方人了解科学评估学科，并为他们提供必要的科学途径，帮助他们在当地管理水产资源。 最后，研究工作将把加拿大科学与旨在提高全球对北极水生生态系统的认识的一系列更广泛的国际举措联系起来，从而帮助提高加拿大在北极科学方面的声誉。
