Near-surface ground ice in Mackenzie Delta region
chercheur principal: Kokelj, Steven V
Année(s) de permis: 2004 2003 2002 2001 2000 2000 1999
Résumé: The proposed research will investigate the physical and chemical characteristics of the near-surface ice-rich zone in sediments of the Mackenzie Delta area. The goals of the research are to investigate the relationship between ice-rich permafrost and fo...


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 Trail Valley site will be accessed by helicopter and snowmobile this year, while the Havikpak Creek site will be accessed by foot and snowmobile. Our field work will be similar to what was done in 2000, with short (<1 week) trips in both April/May and August. Activities at each site will simply include the download of data from the dataloggers on site, and the measurement of snow on the grou...


Water Balance Studies in the Coppermine River Basin: The Chain of Lakes Effect in Space and Time.
chercheur principal: Maric, Robert
Année(s) de permis: 2001
Résumé: The research team will be based out of Yellowknife. Travel to the Ekati Mine site will be by helicopter; travel on site will be on foot. The research team will be in the field for approximately seven days. Characterization of the hydrologic balance of the system under investigation will be completed by the collection of several hundred water samples (each with an approximate volume of 30 ml) at d...


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...


Retrogressive Thaw Slides in the Richardson Range: Climate Change Indicator
chercheur principal: Lacelle, Denis
Année(s) de permis: 2000
Résumé: This is a study of retrogressive thaw sumps produced by the exposure and melting of massive ice in continuous permafrost (Richardson Range, NWT). These sumps are recently occurring and presumably a result of global climate change. This research will recognize retrogressive thaw slumps that have massive ice, identify the type of massive ice (glacier buried or segregated) and measure the rate of ...


Biogeochemistry of Lakes in the Mackenzie Delta
chercheur principal: Lesack, Lance
Année(s) de permis: 2017 2016 2015 2014 2010 2009 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Résumé: The long-term goal of this research is to develop a model of the interacting biogeochemical and hydrologic processes that control the nutrient balance and primary productivity of lakes in the Mackenzie Delta region, and ultimately, a more general model for lakes associated with the floodplains and deltas of major world rivers. Work based at the Inuvik Research Centre will consist of field and lab ...


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 ...


Hydrologic investigation of a Canadian Shield basin
chercheur principal: Spence, Chris
Année(s) de permis: 2001 1999 1998
Résumé: Lower Carp Lake is part of the Yellowknife River and is roughly 22km in size. A number of remote meteorological and hydrometric data collection sites will be constructed around the lake. An island on the lake will be used as a base camp for the research activities. This island is roughly circular rising up to 50m from the lakeshore. A portion of the island is dominated by sandy glacial deposits. M...


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)...


MAGS Moisture Budget Studies (using instrumental weather balloons)
chercheur principal: Strong, G.S.
Année(s) de permis: 1998
Résumé: The purpose of this study is to obtain quantitative information on atmospheric temperatures, moisture, and winds from ground level to 15,000 km (or higher) above sea level (ASL), using instrumented weather balloons (radiosondes). It is proposed to transport the instrumentation and other items by truck to Fort Simpson airport. The system is self contained and can be installed in hours upon arrival....
