Haufe, W. O., Croome, G. C. R.
The program was designed from feasibility studies to develop and evaluate chemical control of S. arcticum in the Athabasca River. This appeared to be the most immediately achievable and economically practical approach to prevention of severe pest outbreaks and to reduction of farm losses in...

In the summers of 1975, 1976, and 1977, several field investigations were carried out to determine the amounts of sulphur deposited in rain, in rain washing off trees, and by direct absorption of SO2 by soil. The impact of this sulphur deposition on soils in the AOSERP study area was also...

Benthic macroinvertebrates were collected at two-week intervals between 1982 May 13 and August 18 at 16 sites along an 85 km stretch of the Athabasca River between Fort McMurray and the Ells River. Samples were collected from gravel bars with a 0.l m2 cylinder sampler. All netting had a mesh...

A field study has been undertaken at the Sandalta lease near Fort McMurray to determine the sulphur dioxide dry deposition velocities above and within a tree canopy. The concentration gradient method has been used to compute fluxes and dry deposition velocities. The covariance of temperature...

Early performance of some native and cultivated grasses on oil sands mine disturbance materials
Download1982
The adaptability of native and cultivated grasses to oil sands disturbance materials is being studied in a field trial in northeastern Alberta. The native grasses originated from the mountains and foothills of the province. The trial was established on blended materials consisting of native...

Air pollution and its effects on various ecosystems has been a subject of increasing controversy. The European forest damage situation has heightened the public's awareness of the problem. Historically, the observed pollution damage was believed to be due mainly to sulphur dioxide pollution. ...

Establishment and vegetation survey of 16 Pinus banksiana – dominated permanent plots for the Athabasca oil sands ecological monitoring project in 1981
Download1982
Sixteen, undisturbed, 5-hectare, permanent plots dominated by Pinus banksiana (jack pine) were established along an impingement gradient of atmospheric emissions from oil sands processing plants north of Fort McMurray in northern Alberta in August of 1981. Four plots were burned over by wildfire...

Minisonde data collected in the Athabasca Oil Sands area from 1975 to 1979 were analysed to determine regional values of roughness length (Zo). A rigorous selection re reduced the working data set to a small fraction of the original size. A least squares technique was used to determine from...
