NSERC Canadian Lake Pulse Network

加拿大的湖泊比其他任何国家都多，并且在饮用水、食物、娱乐和许多其他经济、社会和文化活动方面都严重依赖湖泊。然而，湖泊发挥其生态作用的能力受到全国各地各种人类影响的影响，包括家庭、农业和工业污染，以及土地利用和气候变化。这种情况在未来可能会加剧。令人惊讶的是，没有人从全加拿大的角度看待这个问题，因此不可能回答下列紧迫问题：“加拿大湖泊的健康状况如何？它发生了怎样的变化？将来可能发生怎样的变化？”为了有利于加拿大对湖泊的管理，解决这些问题是我们的主要目标。为了实现这一目标，我们召集了20名加拿大顶级湖泊学家、遥感专家、公共卫生科学家和空间建模师以及主要的国际合作者，以制定创新的方法和技术。为了进一步了解如何最好地满足各利益攸关方的需求，我们与加拿大环境部、加拿大公共卫生署、加拿大航天局、五个省和地区的环境部、乌拉诺斯等几个伙伴进行了接触。为了实现我们的目标，我们将启动一项泛加拿大采样工作，从数百个湖泊中收集前沿信息，包括宏基因组学、新兴污染物、光学和古湖泊学数据。总的来说，这些一致和标准化的数据将使我们能够在学生、其他学员和我们的合作伙伴的积极参与下解决我们的跨学科问题。最终，我们将开发交互式地图来评估加拿大湖泊的过去、现在和未来状态，并为湖泊评估提供从遗传标记到遥感方法的新工具。这些关键成果将使我们的合作伙伴能够改善对湖泊的管理，同时也产生关于湖泊过程的新的基础科学知识，以支持最适当的管理政策。

Canada has more lakes than any other country and relies heavily on them for drinking water, food, recreation, and many other economic, social, and cultural activities. Yet, the ability of lakes to play their ecological role has been affected by diverse human influences throughout the country, including domestic, agricultural and industrial pollution, as well as land use, and climate change. This situation will likely be exacerbated in the future. Surprisingly, a pan-Canadian perspective on this issue has not been pursued and thus it is not possible to answer the pressing questions: "What is the health status of Canadian lakes, how has it changed, and how will it likely change in the future?" To benefit Canada's stewardship of lakes, addressing these questions forms our main goal. To reach this goal, we have brought together 20 of Canada's top limnologists, remote sensing specialists, public health scientists and spatial modellers, as well as key international collaborators, to develop innovative approaches and techniques. To gain further insight into how to best address the needs of various stakeholders, we have engaged with several partners such as Environment Canada, the Public Health Agency of Canada, the Canadian Space Agency, the environment ministries of five provinces and territories, Ouranos. To reach our goals, we will launch a pan-Canadian sampling effort to collect cutting-edge information, including metagenomic, emerging contaminant, optical and paleolimnological data, from hundreds of lakes. Collectively, these consistent and standardized data will allow us to address our cross-disciplinary questions, with the active participation of students, other trainees, and our partners. Ultimately, we will develop interactive maps to assess the past, current and future states of Canadian lakes, and provide new tools for lake assessments ranging from genetic markers to remote sensing approaches. These key outcomes will allow improved stewardship of our lakes by our partners, while also producing new fundamental scientific knowledge about limnological processes to support the most appropriate management policies.
