We are applying for funds to establish the Quttinirpaaq/Lake Hazen Polar Field Laboratory along the shores of Lake Hazen in Quttinirpaaq National Park on northern Ellesmere Island, Nunavut. Human-induced climate change is altering Canadian polar ecosystems at unprecedented rates. By the end of the century, temperatures in the Canadian High Arctic are predicted to increase 2.8-7.8 C relative to 1980-1999. As a result, now is the time to ensure ongoing, new and extensive research programs in the High Arctic are poised to quantify the timing and full extent of change in polar ecosystem function and services. National Parks provide extraordinary areas to conduct this type of research because Parks Canada's mandate is to ensure the ecological integrity of their protected ecoregions, theoretically in perpetuity. Quttinirpaaq National Park is a jewel in the north because of its magnificent diversity of landscapes, which has resulted in both a rich diversity of research programs on Arctic ecology in the past, and a phenomenal location for new research programs to be established now and well into the future. For a relatively small investment from NSERC, the proposed 16'x 32' insulated Weatherhaven field laboratory will provide a clean, safe and warm shelter in which to conduct high-quality research programs, and train university-based HQP (e.g., graduate students) and Northern Community members on High Arctic ecology for decades into the future. Multidisciplinary studies proposed here include those quantifying: 1) nutrient and contaminant deposition and cycling, 2) historical change in climate determined by "paleo-limnological" methods, 3) contemporary net primary production and microbial ecology in High Arctic lakes, 4) net ecosystem exchange of carbon dioxide and methane from aquatic, wetland and tundra surfaces, 5) the impact of climate change on plant species in Arctic tundra vegetation, 6) High Arctic bryophyte (e.g., mosses and liverworts) ecology, 7) Arctic charr genetic diversity and food web dynamics, and 8) density dependent habitat use by lemmings, to name a few.

我们正在申请资金，以在努勒维特埃尔斯米尔岛北部库蒂尼尔帕克国家公园的哈森湖沿岸建立库蒂尼尔帕克/哈森湖极地实验室。人类引起的气候变化正在以前所未有的速度改变加拿大极地生态系统。到本世纪末，加拿大高北极地区的气温预计将比 1980-1999 年增加 2.8-7.8℃。因此，现在是时候确保高北极地区正在进行的、新的和广泛的研究计划能够量化极地生态系统功能和服务变化的时间和全面程度。国家公园为开展此类研究提供了非凡的区域，因为加拿大公园管理局的任务是确保其受保护生态区的生态完整性，理论上是永久的。库蒂尼尔帕克国家公园因其壮丽的多样性景观而成为北方的一颗明珠，这不仅导致了过去丰富多样的北极生态研究项目，而且成为现在和未来建立新研究项目的绝佳地点。对于 NSERC 相对较小的投资，拟议的 16'x 32' 隔热 Weatherhaven 现场实验室将提供一个清洁、安全和温暖的庇护所，在其中开展高质量的研究项目，并在未来几十年内对大学总部人员（例如研究生）和北方社区成员进行高北极生态学培训。这里提出的多学科研究包括量化：1）养分和污染物沉积和循环，2）由“古湖泊学”方法确定的气候历史变化，3）高北极湖泊的当代净初级生产和微生物生态，4）来自水生、湿地和苔原表面的二氧化碳和甲烷的净生态系统交换，5）气候变化对北极地区植物物种的影响 北极苔原植被，6) 高北极苔藓植物（例如苔藓和地钱）生态学，7) 北极红点鲑遗传多样性和食物网动态，以及 8) 旅鼠依赖密度的栖息地利用，等等。
