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 ...


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...


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...


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 ...


Mesoscale climates and paleoclimates of the Baffin Island region
Principal Investigator: Jacobs, John D.
Licenced Year(s): 1994 1993 1992 1991 1990 1988 1987
Summary: This research, begun in 1985, involves measuring climate data such as air and ground temperature, relative humidity, wind speed and direction, solar radiation, precipitation and snow depth. Automatic data collecting stations have been set up to measure these data. The purpose of this research is to document a more accurate picture of the region's climate, to obtain information about the past cli...


Mackenzie Delta Hydrology and Ecosystem Interactions
Principal Investigator: Marsh, Philip
Licenced Year(s): 1993 1992 1991
Summary: The research will study changes in the water levels of a variety of lakes in the Mackenzie Delta. Investigations will include consideration of factors controlling the lake levels, introduction of floodwater from the Mackenzie River, rainfall on to the lake, smowmelt runoff into the lakes and evaporation from the lakes....


Isotope Hydrology and Geochemistry Studies, Manners Creek Basin, N.W.T.
Principal Investigator: Edwards, Thomas W.D.
Licenced Year(s): 1990
Summary: The Researcher and his assistant will collect samples of snow, rain, stream water, pond water and ground water from undisturbed sites in the Manners Creek Basin. Measurements of naturally occurring chemicals and isotopes in surface and subsurface waters will be used to study the movement and mixing of waters in a boreal watershed in the zone of continuous permafrost....


Licence #2775
Principal Investigator: Sklash, Michael
Licenced Year(s): 1982
Summary: 1. Determine the magnitude an timing of groundwater contributions to a stream during summer storm runoff events. 2. Determine the nature of the physical response of groundwater to a rain event. 3. Determine how groundwater chemistry affects surface water chemistry during runoff events....
