Studies of methane release from lakes in the Mackenzie Delta and on Richards Island
Principal Investigator: Orcutt, Beth N
Licenced Year(s): 2017 2016 2015
Summary: The focus of this one-year-long project is to collect an additional annual record of methane release from nine 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. This annual record will allo...

The frontline of permafrost thaw: a transect of eddy covariance towers across the southern Taiga Plains to better understand changing regional carbon and water budgets
Principal Investigator: Sonnentag, Oliver
Licenced Year(s): 2017 2016 2015
Summary: Through this project the research team will address the following objectives: 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 s the reported decrease (increase) in net carbon dioxide (methane) exchange...

Toward Predicting Future Tundra Carbon Balance
Principal Investigator: Lafleur, Peter M
Licenced Year(s): 2017
Summary: The broad goal of this research is to increase the 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 ...

AirMeth
Principal Investigator: Hartmann, Jörg
Licenced Year(s): 2016 2013 2012
Summary: 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...

Measuring Carbon Fluxes at Illisarvik with Eddy Covariance
Principal Investigator: Skeeter, Wesley R
Licenced Year(s): 2016
Summary: 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...

The ecology and paleoecology of benthic macroinvertebrates in the Mackenzie Delta region
Principal Investigator: Quinlan, Roberto
Licenced Year(s): 2016 2015 2014 2013
Summary: 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...

Variability in peat plateau energy balance and water chemistry along a warming gradient
Principal Investigator: English, Michael C
Licenced Year(s): 2013
Summary: 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) ...
