Lakes, rivers and wetlands are major components of the northern landscape and provide important ecosystem services such as drinking water supplies, transport routes and hunting and fishing resources for Aboriginal communities. These living systems are vulnerable to environmental impacts, and are sentinels of global climate change. This request is for funds to help meet the logistic costs associated with our ongoing NSERC Discovery Grant research on the complex question of how northern aquatic ecosystems respond to changes in regional and global climate. Our research will take place at three sets of sites. Most of our research is based out of Ward Hunt Island, Quttinirpaaq National Park, Nunavut, and focuses on ice-dependent lakes and other coastal aquatic ecosystems as indicators of climate change, and as models of ecological survival under environmental extremes. Part of our research will be on lakes in the Resolute Bay area to examine the community structure and function of microbes in the three domains of life (Bacteria, including cyanobacteria; Archaea, including ammonium-oxidizers; and microbial Eukarya). The third set of sites will be on permafrost thaw lakes near Kuujjuarapik, Nunavik, to examine impacts of climate warming. The research program will provide advanced training of students, postdoctoral researchers and technicians, and the results will be communicated to northern communities and other members of the public via reports (including translations into Inuktitut), public presentations, ongoing liaison with schools, TV, radio, newspapers and the internet. Our participation within ArcticNet provides opportunities for collaboration across and within sectors, exchange of data and information via the ArcticNet/CCIN initiative "Polar Data Catalogue" (www.polardata.ca), and communication with northern stakeholders via the Inuit Circumpolar Conference and Inuit Tapiriit Kanatami.

湖泊、河流和湿地是北方景观的主要组成部分，为土著社区提供重要的生态系统服务，如饮用水供应、运输路线以及狩猎和渔业资源。这些生命系统易受环境影响，是全球气候变化的哨兵。这一请求是为了提供资金，以帮助满足与我们正在进行的NSERC发现赠款研究有关的后勤费用，该研究涉及北方水生生态系统如何应对区域和全球气候变化的复杂问题。我们的研究将在三个地点进行。我们的大部分研究都是基于沃德亨特岛，Quttinirpaaq国家公园，努纳武特，并侧重于依赖冰的湖泊和其他沿海水生生态系统作为气候变化的指标，并作为极端环境下的生态生存模式。我们的部分研究将在Resolute Bay地区的湖泊上进行，以研究生命三个领域中微生物的群落结构和功能（细菌，包括蓝藻;古细菌，包括铵氧化剂;和微生物真核生物）。第三组地点将位于努纳维克Kuujjuarapik附近的永久冻土融化湖上，以研究气候变暖的影响。该研究方案将为学生、博士后研究人员和技术人员提供高级培训，研究结果将通过报告（包括翻译成因纽特语）、公开介绍、与学校的持续联络、电视、广播、报纸和互联网传达给北方社区和其他公众成员。我们参与北极网的工作，为各部门之间和部门内的合作、通过北极网/北极信息网倡议“极地数据目录”（www.polardata.ca）交流数据和信息以及通过因努伊特人北极圈会议和因努伊特人Tapiriit Kanatami与北方利益攸关方进行交流提供了机会。
