Understanding and prediction of permafrost thaw impacts on northern ecosystems and water resources
Principal Investigator: Quinton, William L.
Licensed Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2001
Summary: Understanding the integrated eco-hydrological behaviour of ecosystems in the context of thawing permafrost is a major challenge. To meet this, the research team will provide rigorous estimates of the present surface and near-surface water supplies and their inter-annual variability assuming a condition of no permafrost thaw. The research team will also develop critical new knowledge on the eco-hyd...

Studies of the Environmental Effects of Disturbances in the Subarctic.
Principal Investigator: Kershaw, G. Peter
Licensed Year(s): 2000 1999 1998 1997 1996 1995 1994 1993 1992 1990
Summary: The research is planned to see what happens after the surface of the land was changed by clearing of the trees and trenching of the soil in 1985 and 1986, and the spilling of crude-oil in 1988. Ways to fix or lessen these disturbances are being tested to see which are best. Many studies will be done, including measurement of air and soil temperatures, wind speed, moisture, water movement, permaf...

State of the Environment Reporting for Northern Canada
Principal Investigator: Reid, John
Licensed Year(s): 1993
Summary: Under the Canadian Environmental Protection Act and Green Plan, this ongoing study is required to: (1) publish a national report on the state of the environment at regular intervals, (2) develop a set of indicators that measure Canada's progress in achieving environmental goals, and (3) establish an ongoing capability to study resources at risk, ecosystem response and the impact of major disruptio...

Mesoscale climates and paleoclimates of the Baffin Island region
Principal Investigator: Jacobs, John D.
Licensed Year(s): 1994 1993 1992 1991 1990 1988 1987
Summary: This research, begun in 1985, involves measuring climate data such as air and ground temperature, relative humidity, wind speed and direction, solar radiation, precipitation and snow depth. Automatic data collecting stations have been set up to measure these data. The purpose of this research is to document a more accurate picture of the region's climate, to obtain information about the past cli...

Planning for Conservation and Development: Park, Regional, and Ecosystem Approaches
Principal Investigator: Slocombe, D. Scott
Licensed Year(s): 1992 1991
Summary: The researcher and his team will compare conservation and development planning methods and processes in several resource-based regions of the world to assess to what extent such processes take into account environmental and ecosystem problems and needs....

The Role of Soil Algae in High Arctic Ecosystem Development
Principal Investigator: Bliss, Lawrence
Licensed Year(s): 1993 1992 1991 1989 1988
Summary: Professor Bliss and his associates will continue to investigate the development and function of ecosystems within a polar desert -- on the plateau....

The Impacts of Muskoxen on a Hygric Sedge Meadow Plant Community, Northern Banks Island, N.W.T.
Principal Investigator: Romo, J.T.
Licensed Year(s): 1992
Summary: The project examines the effects of a high-density muskoxen populations on a sedge meadow plant community. Two fences exist at the study site to exclude muskoxen and thus provide an ungrazed area used for comparison with the grazed area. Plant species abundance, plant height, grazing use of plant species and weight of plants are some of the data that will be compared among grazed and ungrazed are...
