Influence of changing active-layer thickness on permafrost peatland trace gas exchanges and carbon balance
Principal Investigator: Sonnentag, Oliver
Licenced Year(s): 2017 2016 2015 2014 2013
Summary: The project of the present application is the continuation of year-round eddy covariance measurements of carbon, water and energy fluxes at Scotty Creek, established in 2013 as part of licence #15816. The key methodology is tower-mounted micrometeorological measurements around the eddy covariance technique using an open-path infra-red gas analyzer and a sonic anemometer. These measurements are ...


Airborne Observations in Support of NETCARE
Principal Investigator: Abbatt, Jon
Licenced Year(s): 2015
Summary: The NETCARE observations will be covered the range from Longyearbyen, Svalbard (European Arctic) until Inuvik (NWT – Polar 6 aircraft only) and Barrow (Alaska – Polar 5 aircraft only). The observational platforms will be two aircraft: 1) the Alfred Wegener Institute (AWI) POLAR 5, a modified DC-3 aircraft; and 2) the AWI POLAR 6, also a modified DC-3 aircraft. The two platforms will be coordin...


Modelling the flow and storage components in the lower Liard River valley
Principal Investigator: Quinton, William L.
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2001
Summary: This study is a continuation of a project that began in 2001. The researchers are studying the flow and storage of water in the Scotty Creek watershed. The data they collect will help them to create a model that will do a better job of estimating the volume and timing of basin runoff in wetlands in discontinuous permafrost terrain. The information they have collected so far suggests that peat p...


Modelling the energy and water balance and characteristics of lakes in the Mackenzie River Basin.
Principal Investigator: Rouse, Wayne R
Licenced Year(s): 2001
Summary: The field work associated with the proposed study will consist of the collection of climate data, such as air temperature, humidity, wind speed, wind direction, amount of rain fall, water temperatures and light penetration into the lake. Similar equipment will be used to collect this data at all sites. Air temperature, humidity, wind speed, wind direction, water temperatures and light penetration...


Radar Observations in Support of the Mackenzie GEWEX Study (MAGS)
Principal Investigator: Haykin, Simon
Licenced Year(s): 1999 1998
Summary: A transportable radar system, called the IPIX radar, will be located on the Fort Simpson airport property and operated for 4 or 5 three week periods between August 1998 and August 1999. The system will be left on site but not operated outside these specific periods. This will be used to measure the precipitation and cloud properties within 150 km of the airport. These measurements will be used to...


Influence of the Arctic on Mid-latitude Weather and Climate: Observation of Precipitation Particles at Inuvik.
Principal Investigator: Yamashita, Akira
Licenced Year(s): 1995
Summary: The researchers will observe crystal formation from ice fog through the collection of samples for microscopic observation and through the taking of photographs/video of optical phenomena produced by floating ice crystals. Particle counting and cloud condensation nucleus counting at the observation site will also be done....


Hydrological modelling for a permafrost site and arctic snow accumulation and melt
Principal Investigator: Woo, Ming-ko
Licenced Year(s): 1994 1993
Summary: This on-going study attempts to find out how permafrost affects the groundwater, streamflow and levels of water in wetlands. Measurements such as soil moisture, rainfall, ground and air temperatures, and water level will be taken. This research will help to determine how climatic change affects permafrost and water bodies in the Arctic....


Hydrology and geochemistry of a high arctic lake basin: Colour Lake, Axel Heiberg Island, NWT
Principal Investigator: English, Michael C
Licenced Year(s): 1994 1992 1991
Summary: The researchers are interested in understanding how physical factors (snowmelt, rainfall, solar radiation) play a role in thawing the upper part of the ground each year during the spring and summer. Instruments in the ground will collect data that will estimate how much energy (from the sun) is entering into and melting the frozen ground. Other instruments will measure snowmelt, rainfall and the...


Atmospheric transport of organic contaminants
Principal Investigator: Waite, Don
Licenced Year(s): 1993
Summary: In this study, we will collect air, dust and rain samples on a weekly basis at five Canadian locations during the months of June and July, 1993. Three locations are in the NWT while two locations are in Saskatchewan. The samples will be analyzed in Regina and Edmonton for the presence of certain insecticides, herbicides and PCB's that are known to be transported in the atmosphere....


Current contaminant deposition measurements in precipitation throughout the NWT
Principal Investigator: Gregor, Dennis J.
Licenced Year(s): 1993
Summary: Contaminants are carried in the air to the arctic during the winter when large-scale wind movements bring these contaminants from industrialized locations in North America, Europe and Asia to the north. Snow can collect these compounds from the air and bring them to the ground where they can accumulate. Thus, it is important to study the amount of contaminants in snow to determine the types and ...
