Principal Investigator: Hudak, Dave
Licensed Year(s): 1994
Summary: Researchers will collect data by installing portable doppler radar at Inuvik and Tuktoyaktuk, using weather balloons at Inuvik and Tuktoyaktuk, using the National Research Council Convair 580 aircraft to fly tracks through storms and to release dropsondes, using existing weather observing sites and satellite pictures. The objectives of this study is to better understand and predict weather and th...

Principal Investigator: Kettles, Inez
Licensed Year(s): 1994
Summary: The researcher will map the configuration of peat deposits and permafrost within them using geophysical surveys (ground penetrating radar and EM-31). This will involve setting out a traverse line on foot using measuring tape and flagging tape, taking measurements along the traverse line with hand-held equipment and measuring the depth of peat using a probe. The researcher will drive or fly out ...

Principal Investigator: Jacoby, Gordon C.
Licensed Year(s): 1994 1989
Summary: The researcher will take 5 mm diameter increment core samples from old-aged trees growing near the tree line. This sampling is not harmful to the trees. At two sites the researcher will sample about 10 trees. The samples are processed to produce ring-width and wood- density data for each annual ring. This data will then be statistically compared to meteorological data to make estimates of past cl...

Principal Investigator: Good, Ron
Licensed Year(s): 1994 1993 1993 1992 1992 1991
Summary: The researcher will conduct a geotechnical survey of the area. Components of this survey will include shallow geological drilling, geophysical downholde logging, geophysical electrical sounding and a snow depth transect. A crew will transverse the area by foot and skidoo....

Principal Investigator: Wein, Ross
Licensed Year(s): 1994
Summary: Since fire is most wide spread agent of change in the northern forest, society should know how climatic warming will influence the force. The fire history of the Mackenzie Delta Region is known only through fire suppresion records over the past 25 years. Spot checks on the landscape have been made, but no longer record of 5-20 decades is available. Tree ring approaches will be used in this study...

Principal Investigator: Takeno, Atsushi
Licensed Year(s): 1994
Summary: The research will consist of video-taping mirages in the arctic. In addition, interviews with community residents will be performed in order to examine the ways in which indigenous people have regarded the phenomenon of mirages. This research will result in the production of a film which discusses both the cultural and scientific aspects of mirages....

Principal Investigator: Lehn, W.H.
Licensed Year(s): 1994
Summary: Mirages occur fairly frequently in the arctic. They distort image and landform shapes as well as our perception of distance. This study will examine the underlying causes of mirages by collecting data using time lapse and video photography. This data will be used to examine a theoretical model which attempts to explain the distortion properties of mirages....

Principal Investigator: Schunke, Ekkehard
Licensed Year(s): 2000 1994 1992 1990
Summary: The researchers will continue their study, initiated in 1990, on the geological and hydrological processes which contribute to valley formation in the subarctic and arctic. Data will be collected on various aspects of water runoff and sediment content. This data, along with long-term environmental data collected by Environment Canada, will contribute to our knowledge about valley formation....

Principal Investigator: Falkner, Kelly K.
Licensed Year(s): 1994
Summary: The researchers will be tracking the fate of Mackenzie River waters through the Delta and into the Arctic Ocean by using natural geochemical markers. Water samples will be collected by drilling through the ice at 50 locations along the main channel of the river and out over the shelf. This information is important for understanding the circulation of Arctic Ocean waters, the processes of global ...

Principal Investigator: Hill, Philip R.
Licensed Year(s): 1994 1993 1992
Summary: The researchers will examine the rate of coastal change in the outer Mackenzie Delta region in order to understand the factors contributing to present delta formation and coastal erosion, and to understand how global climate warming may affect coastal change. Surveys on beaches, sand bars and delta lakes will be conducted....
