MOSES Rapid Permafrost Thaw
chercheur principal: Boike, Julia
Année(s) de permis: 2021 2020 2019 2018
Résumé: This licence has been issued for the scientific research application No.5023. The goals for this expedition are to test new equipment for characterizing the energy fluxes from and around thermokarst slumps and to establish a baseline for future subsidence measurements. Additionally, lake and atmospheric methane concentrations in relation to thermokarst slumps will be quantified. The research...


Hydrological Studies, Mackenzie Delta Region
chercheur principal: Marsh, Philip
Année(s) de permis: 2023 2022 2021 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Résumé: The objective of this project is to understand water and energy fluxes in northern regions, and to develop improved models of these processes. Project studies will look at both the atmospheric and surface water budgets of the Mackenzie Basin, with an emphasis on the effects of climate change on hydrology. The rates and processes controlling accumulation of snow, snowmelt, water flux through sno...


Snow accumulation/runoff in high latitude permafrost basins
chercheur principal: Marsh, Philip
Année(s) de permis: 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1990
Résumé: The primary objective of this project is to improve understanding of the changes in water and energy in northern regions, and to develop improved computer models of these processes. The Trail Valley Creek, Hans Creek, and Zed Creek sites will be accessed...


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...


Radar Observations in Support of the Mackenzie GEWEK Study (MAGS)
chercheur principal: Haykin, Simon
Année(s) de permis: 1999 1998
Résumé: The Mackenzie GEWEX Study (MAGS) is the Canadian component of the international effort called the Global Energy and Water Cycle Experiment (GEWEX), in support of a World Climate Research Programme to observe, understand, and model the hydrological cycle and energy fluxes in the atmosphere, at land surface, and in the upper oceans. A transportable radar system, called the IPIX radar, which was set ...


Airborne observations of surface-atmosphere energy exchange over the Mackenzie basin.
chercheur principal: Schuepp, Peter
Année(s) de permis: 1999
Résumé: The Twin Otter, operated by the National Research Council of Canada, will be stationed at the Inuvik Airport (most likely in the RCMP hanger). Support equipment for the aircraft and for data analysis will be shipped to Inuvik and installed at the hanger and in the Finto Hotel. No installation or infrastructure is required elsewhere in the field. Data collected from the aircraft (operating at 60m)...


The Seasonal Sea Ice Monitoring & Modelling Site Project (SIMMS)
chercheur principal: Ledrew, Ellsworth
Année(s) de permis: 1995 1994 1993 1992 1991 1990
Résumé: The researcher will measure the meterorological parameters at two primary sites; first year sea ice and multiyear sea ice. Each site consists of tower based sensors to measure various types of radiation, wind speed, wind direction and air temperatures. In addition, snow and ice temperatures are used. The physical properties of snow (depth, wetness, density, and grain microphotography) will be c...
