chercheur principal:Bliss, Lawrence Année(s) de permis:
1994
Résumé:
We seek to better understand how ecosystems develop in the high arctic following retreat of ice caps. This includes studies of soil development and the influence that rocks play in this as well as studying the development of block crusts of organisms that form on the soil surface. We will also try to understand the role these crusts play in fixing nitrogen and influencing the development of flower...

1992 Résumé:
The researcher will collect samples of small organisms that live on the sea bottom in the Canon and Slidre Fiords of Ellesmere Island. These creatures include small worms, shrimp, starfish, clams and snails. Measurements will be collected on water temperature and the amounts of salt and oxygen in the water. These data will help to relate the distribution of species with the characteristics of ...

Résumé:
This research involves a variety of activities that involve investigating the chemical makeup of ice, streams and lakes. In addition, some work will be conducted on measuring the microscopic and larger organisms (e.g., algae and bugs) present in streams. Most of the field work will be based out of the Inuvik Research Centre with some work conducted in collaboration with Dr. P. Marsh at Trail Val...

1990
Résumé:
The Researcher will collect blood/hemolymph and tissues from representative Arctic marine fish, echinoderm, crustacean and mollusc species. The fish will be netted and the invertebrates dredged. Samples will be analyzed for their fatty acid composition. A sample size of 6-8 individuals will be required from each species....
chercheur principal:McLaughlin, Ronald Année(s) de permis:
1978
Résumé:
To study the effect linear developments (roads, pipelines and seismic lines) have on the northern ecosystems by: (1) documenting changes to the vegetation and terrain and comparing these areas with undistrubed areas. (2) selecting vegetation sample sites for next year's program. (3) sampling fish, small aquatic organisms ...
chercheur principal:Mann, Gary Année(s) de permis:
1977
Résumé:
To conduct a study of water characteristics, fish species, and small water organisms and to inventory physical characteritics (size, width, depth, discharge, and bank conditions) of lakes and streams by ground and aerial surveys....
