Principal Investigator:Quinlan, Roberto Licenced Year(s):
This study will examine the effects of permafrost and flooding on the ecological structure and carbon exchange of contrasting lakes in the Mackenzie River Delta. Permafrost thaw in lake catchments may cause increased transport of organic carbon and dissolved nutrients to lakes with effects on the hydrology and water chemistry of lake environments. Patterned ground marked by ice-wedge polygons is f...
Principal Investigator:Olefeldt, David Licenced Year(s):
The project team intend to study carbon cycling in peatland catchments, in order to determine whether the interactions between wildfire and permafrost thaw causes increased release of greenhouse gases from peatlands and aquatic ecosystems to the atmosphere, and thus cause amplified climate change.
Given the overall objective of the project, the research team intend to address 5 research questi...
Principal Investigator:Wookey, Philip A Licenced Year(s):
This research aims to understand what factors affect 1) the amount of carbon stored in tundra soils, and 2) the conversion of this soil carbon into greenhouse gases (carbon dioxide and methane). In particular, the research team wants to understand how hydrology (which is the distribution and movement of water in soils and streams) might affect the carbon cycle under future global warming. This inc...

The research team intends to study how important greenhouse gases, carbon dioxide and methane, are exchanged between tundra surfaces and the atmosphere. They will measure these exchanges over various tundra types and relate them to environmental variables such as soil properties and weather, in hopes of understanding more about how future climate change will impact the land surface and how these i...
Principal Investigator:Bottenheim, Jan W Licenced Year(s):
The goal of this project is to take part in establishment of a long-term observation network to measure concentrations of two important greenhouse gases (ozone and carbon dioxide) as well as bromine oxide. Bromine oxide is a key chemical reagent determining the presence of ozone accompanied with full set of meteorological data and detailed geographic information across the Arctic Ocean and Hudson ...
Principal Investigator:Worthy, Douglas Licenced Year(s):
Environment Canada’s (EC) Greenhouse Gases (GHGs) Measurement Program conducts high quality ground-based atmospheric measurements of carbon dioxide (CO2) and methane (CH4) and other GHGs from coastal, interior and Arctic regions in Canada. The goal is to provide high quality data to put observational constraints on large-scale sources and sinks, and improve understanding of the carbon cycle. The l...
Principal Investigator:Bhatti, Jagtar Licenced Year(s):
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.
Principal Investigator:Coxson, Darwyn S Licenced Year(s):
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...

Field research for 2007-08 will concentrate on the continued characterization of three of the larger gas seeps observed and reported by the National Energy Board, GSC and Inuvialuit. Reports indicate that some of the larger seeps have been flowing gas at least since the early 1960’s. Active gas seeps may represent a significant source of greenhouse gases to the atmosphere, and also constitute a ha...

Field activities for this project will be covered under various permits being applied for the engineering operations. The Mallik site will be accessed by ice roads from Inuvik. The Mallik wells will be drilled by the Akita 15 rig (local northern company). We expect up to 60 scientists (and 40 operations staff) to be on site at the height of the program. Scientists will be housed in facilities of ...
