In this study, the ability of microorganisms to degrade selected organic substrates in samples of Athabasca River water and water-sediment has been determined. Analysis of laboratory-incubated samples using gas chromatography/ mass spectrometry has shown that trace amounts (100 µg/L) of m-cresol...

A climatological air quality dispersion was developed which provides more powerful analyses capabiIities than are avaiIable in traditional CDM-type models. The model incorporates a time series approach to satisfy identified user needs. The three components of the model are: the time series file...

This report contains watershed boundary delineations and associated drainage areas, and channel profiles on watersheds in the AOSERP study area. Included are watersheds larger than 50 km2 (20 mi2) tributary to the Athabasca River, and tributary sub-basins which contain standard hydrometric...

Crowther, R. A., Lade, B. J.

This study assessed the level of secondary production in the Muskeg River and tested the validity of hypotheses generated by Crowther and Griffing (1979) regarding the trophic structure and function of the Muskeg River as a \"typical\" tributary of the Alberta Oil Sands Environmental Research...

There is no doubt that the Athabasca Oil Sands region has been an eldorado for resource development. The major forces shaping its development, i.e., private enterprise, church missions and government enterprise, have come from outside the region. The economy of the fur trade predominated from...

Psutka, M. M., Harvie, B. W.

A survey of the physical characteristics of the aquatic habitats at 25 locations on the Athabasca and Clearwater rivers was conducted during August 1978. The parameters determined at each site were current velocity and direction, depth, Secchi disc visibility, substrate composition, and...

Studies concentrating upon the epilithon were conducted in five tributary rivers flowing into the Athabasca River: the Muskeg, Steepbank, Hangingstone, MacKay, and Ells rivers. The species composition of the epilithic algae was determined during June to November 1978. Diatoms and blue-green...

While many benefits can result from development of the Athabasca Oil Sands deposits, the associated technological and industrial growth has altered both the physical and social environment in the region. Research in the Human System of Alberta Oil Sands Environmental Research Program is designed...

Monitoring was continued at instrumented sites which were selected in spring 1976, at Mildred Lake, Supertest Hill, the GCOS dike, and near Richardson Tower. Because of budget limitations, sites at Richardson were only monitored occasionally. However, information was obtained at a number of...
