Summary: 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....

Summary: Our goals will be achieved through a multidisciplinary study integrating depositional, diagenetic, and geochemical information into a single comprehensive framework. Over a single field season we will measure stratigraphic thickness of outcrops in the Dismal Lakes Group, Coppermine homocline, NWT and collect small (hand sized) samples from a wide range of different rock types that represent differ...

Summary: A number of remote meteorological and hydrometric data collection sites will be constructed around Lower Carp Lake. An island on the lake will be used as a base camp. This island will be used to operate an automatic weather station and hydrometric stations and associated camp to support scientific studies of the Canadian GEWEX effort and to provide meteorological data for use in weather forecasts ...

Summary: Arctic clouds are dominant on average covering 40 to 60% of the skies over the Arctic ocean. They exert a large influence on the radiation balance in the Arctic, where climate change effects are predicted and observed to be largest in the northern hemisphere. The FIRE III field project will use in-situ measurements obtained using instrumental aircraft, in combination with concurrent satellite dta,...

Principal Investigator: Hallinan, Thomas J.
Licensed Year(s): 1996
Summary: The observations will be made by an all-sky TV camera. The camera is computer controlled and should only require minimal attendance. The camera will record the auroras over Fort Smith with 1 minute resolution, storing the images on coputer disk and transferring them to the Internet. Hoping to use the Upper Air Station as this facility would be ideal for optical observations....

Principal Investigator: Orr, Dwayne
Licensed Year(s): 1995
Summary: The purpose of the campaign is twofold. The first is to fly research instrumentation aboard large scale scientific balloons to measure Cosmic Ray particles entering the earth's atmosphere. The second is to conduct a demonstration flight of newly developed long duration balloon systems for the LDB program. The northern latitudes are desired because of favourable geomagnetic influences on particl...

Principal Investigator: Wescott, E.M.
Licensed Year(s): 1995 1994
Summary: Beams of barium and calcium ions, from a rocket launched from Poker Flats, Alaska, will be released into the aurora. These beams will be observed using two low-light-level TV systems set up outside the Upper Air Station in Fort Smith. Each system will be filtered for barium ion light and calcium ion light respectively. The data will be recorded on video tape. The experiment will take place nea...

Principal Investigator: Sofko, George J
Licensed Year(s): 1994
Summary: The Sapphire North Radar System uses 2 transmitters, at Sachs Harbour and Rankin Inlet, and a common receiver at Yellowknife. This system measures speeds of structures in the ionosphere (upper atmosphere) in order to study the transfer of energy from the solar wind to the earth. This energy transfer is most apparent during "magnetic storms" when there are displays of northern lights. The researc...

Summary: The primary objective of the research is to characterize the physical processes of the interaction between sea ice, the ocean and the atmosphere. Monitoring of this interaction is necessary to understanding the impacts of a carbon dioxide (CO2) warming of arctic regions. The researchers will continue to collect data for this long-term study....

Principal Investigator: Kelly, John D.
Licensed Year(s): 1994 1993
Summary: The researchers are continuing their long term study of the earth's atmosphere from the newly established scientific facility in Resolute Bay. Data will be collected in order to understand the influence of the sun on the earth's atmosphere....
