Recent changes in carbon source-sink relationships and greenhouse gas emissions in forest and peatland ecosystems along the Mackenzie Valley region of Canada
Principal Investigator: Bhatti, Jagtar
Licensed Year(s): 2011 2010 2009 2008 2007
Summary: The objectives of this research project are to: 1. map and assess changes in the distribution and composition of forest and peatland ecosystems due to climate changes; 2. estimate carbon storage (and variation) in boreal to arctic ecoregions of the Mackenzie valley; and 3. assess interannual and seasonal variations and key processes controlling carbon dioxide (CO2) and methane (CH4) dynamics. ...


Climate Change Impacts on Canadian Arctic Tundra Ecosystems: Interdisciplinary and Multi-scale Assessments
Principal Investigator: Coxson, Darwyn S
Licensed Year(s): 2008 2007
Summary: The objective of this research is to study how northern soils in close proximity (geospatially linked soils) cycle nitrogen and carbon and produce greenhouse gases. Describing these links will allow forecasting on how the soils respond to climate change. Three transects with 31 sampling locations will be set up. At each location a Time Domain Reflectometry (TDR) probe and thermocouple will be i...


Climate Geochemistry
Principal Investigator: Guo, Laodong
Licensed Year(s): 2005 2004
Summary: The purpose of this study is to collect river waters to determine the concentrations of dissolved organic carbon, particulate organic carbon, and nutrients, including nitrate, phosphate and silicate, and to examine their temporary variations related to c...


Canadian Arctic Shelf Exchange Study (CASES)
Principal Investigator: Fortier, Louis
Licensed Year(s): 2004 2003 2002
Summary: The Canadian Arctic Shelf Exchange Study (CASES), a major international effort under Canadian leadership, aims to understand the biogeochemical and ecological consequences of sea ice variability on the Mackenzie Shelf (Beaufort Sea) and provide the infor...


Carbonate-Hosted Lead-Zinc (Mississippi Valley Type) Occurrences in Northern Alberta and Southern Northwest Territories.
Principal Investigator: Turner, William
Licensed Year(s): 2002 2001
Summary: Transport of the research team to sites will be by truck, contingent on road access. Tent camps will be established for housing in the field. The camp will consist of 2 researchers, for the months of August and September, with possible sporadic visits by other researchers throughout the summer. Field activities will involve examining and documenting lead-zinc occurences, and collecting lead-zi...


A study of the supply of organic bromine from the ocean to the arctic atmosphere.
Principal Investigator: Moore, Robert M.
Licensed Year(s): 1993 1992
Summary: Previous research has indicated that compounds containing bromine could play a role in the destruction of the ozone layer. This study is part of on-going research that is examining how important northern marine waters are as sources of bromine to the Arctic atmosphere. Seawater, snow and ice will be collected and assessed for bromine. In addition, measurements will be taken to determine if seaw...


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 team will continue to research the role of soil algae in high arctic ecosystem development....
