The present proposal for northern supplement funding complements my ongoing NSERC-funded research activities on the "Impacts of climatic change and environmental stress on aquatic ecosystems" (NSERC Discovery grants 2003-2007, 2008- submitted). It seeks additional logistic support for the continuation of a project that promotes the development of a long-term field-based survey and monitoring network of remote northern lakes and ponds distributed along a latitudinal transect across northwestern Québec (Nunavik), the Foxe Basin region and Bylot Island (Nunavut) (ca. 55-73 degrees lat. N; 77-85 degrees long. W). Repeated observations of selected parameters will allow us to continue our monitoring of limnological change and detect trends in these precious northern freshwater resources, as well as provide baseline data against which to measure ongoing changes in these fragile northern environments. Funding for these survey and monitoring activities will also allow us to better integrate paleo- and neo-limnological approaches (process-based studies) in an effort to improve our understanding of the response of northern freshwater ecosystems and their biota to global climate change, as well as to natural and anthropogenic environmental stresses and disturbances.

目前的北方补充资金提案补充了我正在进行的 NSERC 资助的研究活动，即“气候变化和环境压力对水生生态系统的影响”（NSERC 发现赠款 2003-2007 年，2008 年提交）。它寻求额外的后勤支持，以继续实施一个项目，该项目促进开发长期实地调查和监测网络，该网络针对分布在魁北克西北部（努纳维克）、福克斯盆地地区和拜洛特岛（努纳武特）（约北纬 55-73 度；西经 77-85 度）的纬度断面分布的偏远北部湖泊和池塘。对选定参数的重复观测将使我们能够继续监测湖泊学变化并检测这些珍贵的北方淡水资源的趋势，并提供基线数据来衡量这些脆弱的北方环境的持续变化。这些调查和监测活动的资金还将使我们能够更好地整合古湖泊学方法和新湖泊学方法（基于过程的研究），以提高我们对北部淡水生态系统及其生物群对全球气候变化以及自然和人为环境压力和干扰的响应的了解。
