Canada Research Chair in Environmental Change

环境研究人员和管理人员面临的最紧迫的挑战之一是缺乏长期监测测量，因为需要这些数据来评估生态系统变化的趋势，确定自然变化与人为变化的相对影响，并设定现实的缓解目标（即确定参考或背景条件）。幸运的是，湖泊在其沉积物剖面中记录了过去的环境变化，可以解释和使用这些缺失的仪器数据。这项建议将发展和应用古湖泊学方法来研究许多关键的环境问题，包括气候变化（特别是在敏感的北极和山区）、水质问题，以及污染物运输和相关问题的研究。

One of the most pressing challenges faced by environmental researchers and managers is*the lack of long-term monitoring measurements, as these data are required to assess trends in ecosystem change, determine the relative impacts of natural versus anthropogenic changes, and set realistic mitigation goals (i.e. define reference or background conditions). Fortunately, lakes archive a record of past environmental change in their sediment profiles, which can be interpreted and used in lieu of these missing instrumental data. This proposal will develop and apply paleolimnological approaches to study many key environmental issues, including climatic change (especially in sensitive Arctic and mountain regions), water quality problems, as well as studies on contaminant transport and related issues.
