Wallace, R. R., Lock, M. A.

The colonization of limestone bricks and bitumen coated limestone bricks by benthic river organisms was followed over time. After nine weeks of colonization, no massive increase in the numbers of bacteria on the bitumen was noted, suggesting that degradation was not proceeding rapidly. However,...

Davies, M. J. E., Leavitt, E. D., Rudolph, R. C., McKenna, R. R., Davison, D. S.

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...

Alberta Environment is in the process of reviewing the scientific and technical basis for refinement of a regulatory approach to the environmental impact of present and future industrial development in the Athabasca oil sands region. The review has encompassed the results of 10 years (1975 to...

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...

Lock, M. A., Wallace, R. R.

The epilithic microbial and micro-invertebrate communities under conditions of light and shade were studied from April to November 1978. During a period of increasing light intensity from May to June, the level of chlorophyll a (an algal biomass indicator) and numbers of Bacillariophyta in the...

This project, which was a continuation of 1976-77 activities of AOSERP Project AF 2.0, \"Interim Report on Ecological Studies on the Benthic Invertebrates of Various Rivers in the Alberta Oil Sands Environmental Research Program Study Area, Northeastern Alberta\", was to describe the basic...

Heidorn, K., Stevens, D., Todd, S., Fellin, P., Davis, C. S.

The data and network operating procedures from the precipitation and snow sampling networks in the AOSERP area of Alberta were reviewed and assessed. The data was first reformatted into NAQUADAT format and then quality assured by several screening procedures including outlier tests, simultaneous...

Wallace, R. R., Barton, D. R.

This report details preliminary experimental and survey research on benthic communities affected by selected hydrocarbons and tailings sludge produced by existing oil sands mining and upgrading operations. Taxonomic surveys of macrobenthic communities were carried out in the Muskeg and Steepbank...
