Summary: The goal of this project is to identify and collect remote sensing and field data to support the science necessary to investigate the impacts and consequences of the 2014-15 wildfires in Northwest Territories, Canada and to better understand the vulnerability of the Carbon-rich boreal peatlands to burning. Field crews will navigate to pre-selected sample locations and collect at each location: ...

Summary: 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 team intend to address five research questions: ...

Summary: The research team will use natural environmental archives (lake sediment and peat cores) to characterize the forest fire history in the study region and test the relationship between fire events and metal accumulation over recent centuries. Study sites will be selected along a gradient of recent forest fire activity with some study sites located in areas of the latest burns (2014-15) to examine th...

Summary: The objective of this project is to evaluate bryophytes regeneration in Northwest Territories burned peatlands to improve the understanding of the structure of mosses ecosystems. This new knowledge should improve the restoration method of disturbed peatlands where the reintroduction and regeneration mosses are problematic. Several sites will be studied in order to have a range of plant communit...

Licensed Year(s): 2014 2013
Summary: The research team aims to study if permafrost thaw in peatlands is linked to rapid losses of organic matter. The field work will focus on extracting a number of cores from different peatland sites that differ in their permafrost status and in fire history. By examining the peat layers in the core the team will be able to reconstruct the history of the site and to link changes in permafrost conditi...

Summary: The objective is to quantify the amount of fuel combustion and carbon losses during wildfires in boreal conifer forests and peatlands. These data will allow us to quantify climatic and weather controls on the severity of biomass burning. Boreal forests and peatlands store a large amount of carbon in vegetation and soils. Climate change is predicted to increase summer drought, which could mak...

Principal Investigator: Waddington, J.M.
Licensed Year(s): 2010 2009
Summary: To investigate how the amount of peat consumption during wildfire in bogs or fens (muskeg), is affected by weather, fire behaviour, and properties of the tree canopy. Researchers will manually measure various aspects of the peat, such as total peat depth and the proportion of unburned peat present in the area. Peat depth measurements will be made by driving a 2.5cm steel rod into the peat with...

Summary: The Fort Simpson region has a high density of open water and wetlands that occupies the zone of discontinuous permafrost. Discontinuous permafrost terrain is particularly sensitive to the effects of climatic warming because pronounced changes in water storage and runoff pathways could occur with small additional ground heating. The major peatland types of this region include channel fens, flat bog...

Summary: This project will examine the effect of Great Slave Lake on air and surface temperatures in peatlands near Yellowknife. Each of the sites that along the Ingraham Trail that were instrumented with air and surface temperature sensors the previous summer wi...

Summary: The objectives of the research are to become familiar with the vegetation and landforms of northern Canada, and to collect vegetation and biophysical data for ground truth of remote sensing and carbon modeling activities. The Dempster Highway provides a...
