Canada contains 60% of the world's lakes, 85% of which are small (<100 ha) and shallow. This research focuses on the investigation of the environmental sensitivity of these lakes to both short and long term climate change. This study will be carried out in Nova Scotia where lakes provide drinking water for over 500,000 people and are a significant hydroelectrical and recreational resource (estimated $70 M/year). They are also essential habitat for several species at risk including the Blanding's Turtle and the Atlantic Whitefish. There is much concern regarding water quality and habitat stability in these lakes, especially in light of predicted climate change. Lake sediment cores will provide information on how these lakes responded to past climate change. The physical and chemical properties of these lakes will be investigated to better understand why they exhibit a wide range of responses to both long and short term climate change. This research will also apply advanced computer modelling techniques to develop predictive models of the thermal structure of lakes. This technique has the potential to substantially reduce the time required to collect meaningful datasets for modeling and risk assessment.

加拿大拥有世界上60%的湖泊，其中85%的湖泊又小又浅（<100公顷）。这项研究的重点是调查这些湖泊对短期和长期气候变化的环境敏感性。这项研究将在新斯科舍省进行，那里的湖泊为50多万人提供饮用水，是重要的水电和娱乐资源（估计每年7 000万美元）。 它们也是几种濒危物种的重要栖息地，包括布兰丁海龟和大西洋白鱼。 人们对这些湖泊的水质和生境稳定性非常关注，特别是考虑到预测的气候变化。湖泊沉积物岩心将提供这些湖泊如何应对过去气候变化的信息。 这些湖泊的物理和化学性质将被调查，以更好地了解为什么他们表现出广泛的长期和短期气候变化的反应。 这项研究还将应用先进的计算机建模技术，开发湖泊热结构的预测模型。这种技术有可能大大减少收集有意义的数据集进行建模和风险评估所需的时间。
