Principal Investigator:Sonnentag, Oliver Licenced Year(s):
This project will address the following questions:
1) What is the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system?
2) How do these two types of feedback differ between the discontinuous and continuous permafrost zones?
3) Is the reported decrease (increase) in net CO2 (CH4) exchange based on plot- (<1m2) and ecosystem-scale (~1km2) flux m...
Principal Investigator:Abbatt, Jon Licenced Year(s):
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...

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...
Principal Investigator:Rouse, Wayne R Licenced Year(s):
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...

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...
Principal Investigator:Yamashita, Akira Licenced Year(s):
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....
Principal Investigator:Woo, Ming-ko Licenced Year(s):
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....
Principal Investigator:English, Michael C Licenced Year(s):
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...
Principal Investigator:Waite, Don Licenced Year(s):
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....
Principal Investigator:Gregor, Dennis J. Licenced Year(s):
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 ...
