Lichens as indicators of trace-element air pollution in the environment and environmental controls on plant species richness and composition along an arctic river
chercheur principal: Gould, William
Année(s) de permis: 1994 1993 1992 1991 1990
Résumé: Project 1: Small samples of lichens will be collected from approximately 20 sites located along the Hood River and analyzed for contaminants. Lichens are good indicators of the types of air-borne contaminants that have been carried north to the arctic since they absorb their nutrients from the air. Project 2: The researcher will examine plant communities along the Hood River in order to study th...


Influence of petroleum contamination on soil thermal properties
chercheur principal: Winnicky, Kim
Année(s) de permis: 1993
Résumé: In this study, oil spill sites will be identified and information will be collected on the vegetation, soil and amount of surface oil present. Five soil cores from the sample sites will be collected and analyzed for oil concentrations as well as used for experimentation in order to assess soil thermal properties. The researcher will drive to the study site (Mile 222 on the Canol Road) from Ross ...
