Principal Investigator: Lehn, W.H.
Licensed Year(s): 1987
Summary: To study the optical refraction and image transmission in the lower layer of the atmosphere, in particular under conditions of temperature inversion. To improve the understanding of these processes, and to continue to search for remote sensing techniques that provide temperature profiles through optical measurements....

Principal Investigator: Lehn, W.H.
Licensed Year(s): 1985
Summary: To further study meteorological optics by photographic recording of land forms and their refracted images over horizontal lines of sight; measurement of refraction and horizon shift by theodolite; local surveys of the photographed land forms and observation sites....

Principal Investigator: Timoney, Kevin, P.
Licensed Year(s): 1984
Summary: Field sampling coupled with air photo interpretation are used to describe vegetation zonation. Objectives include: a) a delimitation of the subarctic forest-tundra ecotone; b) geographic variation in the vegetation, sorts, species ranges, and width and position of the forest-tundra....

Principal Investigator: Jeffries, Martin O.
Licensed Year(s): 1984
Summary: To carry out a study of the structure, behaviour and origin of the Ward Hunt Ice Shelf. To carry out a snowmobile ground truth survey of the landfast sea ice between the mouth of Nansen Sound and Clements Markham Inlet. Ice cores will be taken, aerial photography and radar flights will be used....

Principal Investigator: Wein, Ross
Licensed Year(s): 1984
Summary: To gather information on fire behaviour, the effects of fire on plants and animals, and the social implications of fire management. Satellite imagery processing, aerial photography and ground censusing will be used....

Principal Investigator: Lehn, W.H.
Licensed Year(s): 1984
Summary: To investigate optical refraction in the lower layers of the atmosphere (anomalous refraction, such as the superior mirage and optical ducting). Photographic recording of land forms and their refracted images: measurement of refraction and horizon shift; some measurement of atmospheric temperatures in the lowest layers (10-15 meters); local surveys of the photographed land forms....

Principal Investigator: Sims, Richard A.
Licensed Year(s): 1981
Summary: To continue a series of aerial surveys of reindeer rangeland. Some samples of soil and vegetation will be collectd. The objective is to set up and test various types of remote sensing techniques....

Principal Investigator: Muller, David S.
Licensed Year(s): 1979
Summary: To measure the elevation of marine deposits and to collect samples for laboratory analysis and dating. To conduct radio echosounding to try to determine if submerged glacial deposits and shore forms can be recognized....

Principal Investigator: Howland, William G.
Licensed Year(s): 1978
Summary: The application of remote sensing techniques to vegetation and terrain mapping....

Principal Investigator: Howland, William G.
Licensed Year(s): 1976
Summary: 1) Familiarization with plant distribution, 2) Physical site analysis, 3) Study reflectivity of newly emerged plants....
