NSERC Canadian Lake Pulse Network

加拿大拥有比其他任何国家都多的湖泊，并严重依赖于它们的饮用水、食物、娱乐和许多其他经济、社会和文化活动。然而，湖泊发挥生态作用的能力受到了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，没有人在这个问题上寻求加拿大的泛视角，因此不可能回答这些紧迫的问题：“加拿大湖泊的健康状况如何，它是如何变化的，以及它未来可能会如何变化？”为了有利于加拿大对湖泊的管理，解决这些问题构成了我们的主要目标。为了实现这一目标，我们聚集了20名加拿大顶尖的湖泊学家、遥感专家、公共卫生科学家和空间建模人员，以及主要的国际合作者，以开发创新的方法和技术。为了进一步了解如何最好地满足不同利益攸关方的需求，我们与加拿大环境部、加拿大公共卫生局、加拿大航天局、五个省和地区的环境部、Ouranos等几个伙伴进行了接触。为了实现我们的目标，我们将发起一项泛加拿大采样工作，从数百个湖泊收集尖端信息，包括元基因组、新出现的污染物、光学和古矿物学数据。总的来说，这些一致和标准化的数据将使我们能够在学生、其他受训人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，我们将开发互动地图来评估加拿大湖泊的过去、现在和未来状态，并为从遗传标记到遥感方法的湖泊评估提供新的工具。这些关键成果将使我们的合作伙伴能够改进对我们湖泊的管理，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.********
