No impact on jack pine physiology was found when concentrations of the dominant pollutants from Oil Sands operations equivalent to 104 years of soluble disposition were added to intact soil cores

In the course of the program, 7,608 shovel tests were excavated for the purpose of locating prehistoric sites in Syncrude's Bituminous Sands Lease No. 22.

describe existing environmental conditions in, and to document natural biological colonization of, the West Interceptor Ditch and determine the degree of biological colonization of lower Beaver Creek

Emphasis is placed on processes influencing temporal and spatial patterns in circulation, stratification and saline water distributions. Owing to its density, the high salinity effluent tends to sink

The study consisted of three parts: 1) A general reconnaissance early in the study period including a survey of fish species, benthic invertebrates, periphyton (attached algae) and water quality

Studies were continued in 1976 into the improvement of a five year old revegetated area on a tailings sand dike by the implementation of different fertilizer programs.

Ten sites in the system were sampled regularly for physical-chemical parameters, phytoplankton, zooplankton and benthic macroinvertebrates. Additional surveys were done for fish, aquatic macrophytes,

Peak discharge for the year was 22.5 m3/sec and the low 0.2 m3/sec. A total of 80 benthic macroinvertebrate taxa and 19 fish species were collected.

Of the 14 species seeded in 1976, only Lupine and the oat cover crop did not grow in 1977. A comparison of fall seeding versus spring seeding indicated that fall seeding could be successfully used

While a total of 11 species were encountered in the study area, only 6 were recorded in the upper diversion system (i.e., upstream of the Poplar Creek dam).
