The Arctic in Flux: How has Recent Climate Change Affected Contaminant Transport and Uptake in Aquatic Arctic Systems?
Principal Investigator: Blais, Jules M
Licenced Year(s): 2013 2012
Summary: This research will determine how the recent and dramatic climate changes in Arctic freshwater have affected the transport and fate of anthropogenic contaminants to freshwater systems, two of the largest threats facing northern communities and ecosystems. This research will develop new tools to examine how the fate of anthropogenic contaminants is affected in Arctic regions under different climate ...


Improving Habitat Connectivity to Enhance Productive Capacity of Arctic Freshwater Ecosystems
Principal Investigator: Tonn, William
Licenced Year(s): 2014 2013 2012 2011 2010 2009
Summary: The objectives of this research project are: to study the freshwater ecology, hydrology, and hydraulics of small lakes and streams in the Lac de Gras basin before habitat modification; to monitor the changes in ecosystem productive capacity resulting from habitat modifications designed to increase habitat connectivity and fish passage; and to assess the effectiveness of such habitat modifications ...


Investigating the cumulative effects of environmental change and human activity in the Tathlina watershed
Principal Investigator: Laidlaw, Shawn
Licenced Year(s): 2013 2012
Summary: The purpose of this project is to: 1) coordinate monitoring and research efforts in the watershed between the community, government, and universities; 2) understand current aquatic health of the watershed using water quality, macroinvertebrates, aquatic furbearers and fish as indicators of ecosystem health; 3) understand historical environmental change and contaminant loading in the watershed u...


Biocomplexity of frost-boil ecosystems
Principal Investigator: Walker, Donald A
Licenced Year(s): 2006 2005 2004 2003
Summary: The central goal of this project is to understand the complex linkages between biogeochemical cycles, vegetation, disturbance, and climate across the full summer temperature gradient in the Arctic in order to better predict ecosystem responses to changing climate. A group of 4-6 researchers will fly to Green Cabin on Banks Island, on to Mould Bay on Prince Patrick Island, and then to Isachsen o...


Evaluation of New Technologies for Environmental Impact Assessment in the Offshore, Canadian Beaufort Sea
Principal Investigator: Blasco, Steve M
Licenced Year(s): 2001
Summary: The Coast Guard vessel CCGS Nahidik will be used as a research platform to conduct offshore surveys in the Beaufort Sea. A regional grid of survey lines which were first surveyed in the1980's will be resurveyed as follows: (1) using a 300kHz short range multibeam echo sounder (Simrad EM 3000) to produce along-track maps of the topography and character of the seabed. These tracks will be approxi...


An Exploratory Evaluation of the Effect of the Climate Change During the Past Two Centuries on Structure of Jack Pine Forests.
Principal Investigator: Osawa, Akira
Licenced Year(s): 1999
Summary: The main objective of the proposed research is to reconstruct the structure of monospecific forests of different ages, and to explore whether or not the recent climate change has affected the structure of the forests in northern Canada. Pure stands of Jack pine or aspen will be studied in Wood Buffalo National Park. The intent is to determine the effect of the so-called Climate Change on those f...


Wildlife and Fisheries Habitat Survey at Ranger Oil's Exploratory Drilling Project near Tulita (Fort Norman).
Principal Investigator: Melton, Derek
Licenced Year(s): 1997
Summary: Main objective is to establish baseline wildlife & fisheries habitat conditions prior to start of Ranger Oil's winter exploration drilling program. All sampling will be done over a 2-3 day period in mid-September. Three well sites are planned for drilling. Well site 1 is near Nota Creek & accessed by the Norman Wells-Tulita winter road plus an existing short cutline. Well site 2 is near Bear Rock ...
