NSERC Canadian Lake Pulse Network

加拿大的湖泊比其他任何国家都多，并严重依赖它们提供饮用水，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，以及土地使用和气候变化。这种情况今后可能会加剧。令人惊讶的是，在这个问题上没有采取泛加拿大的观点，因此不可能回答紧迫的问题：“加拿大湖泊的健康状况如何，它如何变化，以及它将来可能如何变化？“为了使加拿大对湖泊的管理受益，解决这些问题是我们的主要目标。为了实现这一目标，我们汇集了加拿大20位顶尖湖沼学家、遥感专家、公共卫生科学家和空间建模者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、加拿大公共卫生局、加拿大航天局、五个省和地区的环境部、Ouranos等合作伙伴进行了接触。为了实现我们的目标，我们将发起一个泛加拿大的采样工作，以收集尖端信息，包括宏基因组，新兴污染物，光学和古湖沼学数据，从数百个湖泊。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，以评估加拿大湖泊的过去，现在和未来的状态，并提供新的工具，湖泊评估，从遗传标记到遥感方法。这些关键成果将使我们的合作伙伴能够更好地管理我们的湖泊，同时也产生关于湖沼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.
