ABoVE Permafrost Dynamics Observatory
chercheur principal: Miller, Charles E
Année(s) de permis: 2019
Résumé: The objective of this project is to collect physical and geophysical measurements quantifying permafrost susceptibility to ABoVE's internationally-available dataset. Researchers can access these data to bolster understanding of environmental processes and the ability to remotely-sense these on a regional scale. Airborne remote sensing missions from August 2017, 2018, and August of 2019 by NASA'...

Variability in peat plateau energy balance and water chemistry along a warming gradient
chercheur principal: English, Michael C
Année(s) de permis: 2013
Résumé: 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) ...

Thermal State of Permafrost
chercheur principal: Siegfried, Dian
Année(s) de permis: 2016 2013 2010
Résumé: The objective of this project is to continue an ongoing long-term monitoring of permafrost temperatures on Banks Island and Mould Bay. The research team is currently monitoring active layer and permafrost temperatures, active layer soil moisture, air temperature, and snow depth at this site using a datalogger and sensors from Campbell Scientific (Logan, UT). In August, 2010 the research team vi...

The Effect of Great Slave Lake on Air and Surface Temperatures in Peatlands near Yellowknife
chercheur principal: Karunaratne, Kumari C
Année(s) de permis: 2005 2004 2003
Résumé: This project will examine the effect of Great Slave Lake on air and surface temperatures in peatlands near Yellowknife over a period of three years. Air and surface temperatures are components of the climate/permafrost relation, and are used in numerica...

Spring Melt Hydrological Investigations at Daring Lake, N.W.T.
chercheur principal: English, Michael C
Année(s) de permis: 2003 2002 2001 2000
Résumé: Tthe objective of this study is to continue research examining the hydrological and energy budget of small arctic esker lake basin during the spring melt period. The intent of this research is to understand the relationship between the energy budget and changes in soil moisture, rates of evapotranspiration, and changes in water discharge from a small tundra basin underlain by permafrost. Transpo...
