chercheur principal:Lehn, W.H. Année(s) de permis:
1987
Résumé:
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....
chercheur principal:Lehn, W.H. Année(s) de permis:
1985
Résumé:
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....
chercheur principal:Timoney, Kevin, P. Année(s) de permis:
1984
Résumé:
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....
chercheur principal:Jeffries, Martin O. Année(s) de permis:
1984
Résumé:
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....
chercheur principal:Wein, Ross Année(s) de permis:
1984
Résumé:
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....
chercheur principal:Lehn, W.H. Année(s) de permis:
1984
Résumé:
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....
chercheur principal:Sims, Richard A. Année(s) de permis:
1981
Résumé:
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....
chercheur principal:Muller, David S. Année(s) de permis:
1979
Résumé:
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....
