Principal Investigator:Hartmann, Jörg Licenced Year(s):
The objectives of this survey are to establish patterns of methane (CH4) concentration in the atmosphere over the Mackenzie delta region and to quantify the emission of CH4 from these areas. Together with the data from previous data the research team should be able to estimate the annual contribution of the Mackenzie delta region to the atmospheric methane budget. Furthermore the research team wil...
Principal Investigator:Skeeter, Wesley R Licenced Year(s):
The study will measure carbon dioxide (CO2) and methane (CH4) fluxes at Illisarvik during the peak of the growing season using a combination of eddy covariance and gas chamber methods. The primary objective will be to determine the magnitude of CO2 and CH4 fluxes and determine whether sequestration offsets emission. Secondary objectives will be to observe the temporal and spatial variability of th...
Principal Investigator:Orcutt, Beth N Licenced Year(s):
The focus of this project is to study methane release from different lakes in the Mackenzie Delta and Richards Island area, with a focus on capturing a full ice in/ice out cycle, to determine how much methane is released from lakes under different conditions and how microorganisms increase or decrease methane release.
As part of this project, eight experiments the size of a milk crate were dep...
Principal Investigator:Lesack, Lance Licenced Year(s):
The objectives of this research are to: 1) Improve our understanding of microbial carbon-processing in Mackenzie Delta lakes and how it is affected by the changing water levels/ and 2) Decipher the impact of water level changes on the ability of the Mackenzie Delta to affect riverine nutrient flow to the ocean.
Specific activities for the coming field season include the following:
Principal Investigator:Lafleur, Peter M Licenced Year(s):
The broad goal of this research is to increase understanding of tundra carbon balance of terrestrial and aquatic ecosystems and predict into the future the impacts of climate warming on these systems.
Since the research team are interested in all aspects of the tundra carbon balance a variety of methods are employed. These can be broken down into 4 basic categories:
1. Tundra-atmosphere flux...
Principal Investigator:Sonnentag, Oliver Licenced Year(s):
The objectives of this research project are to: 1) determine the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system; 2) determine how these two types of feedback differ between the sporadic and discontinuous permafrost zones; 3) determine if the reported decrease (increase) in net carbon dioxide (methane) exchange based on flux measurements made...
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:English, Michael C Licenced Year(s):
This research is physically based on a peat plateau and a peat bog, both close to Yellowknife. There are two primary objectives to this research. The first involves quantifying surface energy balances in areas where degradation of peat is pronounced and where it is not. Suprapermafrost water from the degraded and non-degraded sites will be analyzed for nutrients and dissolved organic carbon (DOC) ...
Principal Investigator:Dallimore, Scott R Licenced Year(s):20082007
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 ...
Principal Investigator:CLARK, Ian D. Licenced Year(s):
Data will be collected that can help to predict climate of the near future and determine the impact of temperature change on northern hydrology. The investigator will attempt to better understand how methane-producing bacteria function giving us a better understanding of their feedback on climate change. The research area is a quarry along the Dempster highway east of Campbell Lake. This site w...
