Studies concentrating upon the epilithic algal community were conducted in five tributary rivers flowing into the Athabasca river: the Muskeg, Steepbank, Hangingstone, MacKay, and Ells rivers. Numerically, cyanophycean algae (Lyngbya aerugineo-caerulea, Phormidium sp., Calothris braunii, Nostoc...
A longitudinal physico-chemical and algal survey of five rivers flowing through the AOSERP study areaDownload
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...
A preliminary study of chemical and microbial characteristics of the Athabasca River in the Athabasca oil sands area of northeastern AlbertaDownload
A literature review and evaluation of methods used to determine rates of bacterial uptake (heterotrophic assimilation) of organic substrates in fresh water systems was undertaken. The uptake of a \"universal\" substrate - radiolabelled glutamic acid - was determined in order to assess the effects...
Analyses are given for up to 12 metals and 4 pesticides with PCBs, of aquatic environment from 15 study sites along or near the Athabasca River from Fort McMurray north to the confluence of the Peace and Slave Rivers. There were 560 fish (8 species), 15 water, 14 sediment and a few phyto-plankton...
Acute lethality of mine depressurization water to trout-perch (Percopsis omiscomaycus) and rainbow trout (Salmo gairdneri) Volume IIDownload
Volume 2 In order to conduct oil sands mining operations in the surface mining region of the Athabasca oil sands deposits, most regions require depressurization of the basal sandstone formations. The groundwater produced by depressurization operations is of poor enough quality to be toxic to...
As a result of industrial development in the Athabasca oil sands area of northeastern Alberta, concerns have been raised regarding potential impacts on surface water quality in the area. It is of particular concern that the cumulative effects of increasing development of the oil sands may create...
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...
Aquatic biophysical inventory of major tributaries in the AOSERP study area. Volume I: Summary reportDownload
This report summarizes and compares the physical characteristics of nine streams within five watersheds (Firebag, Muskeg, Steepbank, MacKay, and Ells) in the AOSERP study area. The distributions and relative abundances of fish in each stream and watershed are also described and related to the...
This report investigates the relationship between certain hydrocarbons that are present naturally, or could be introduced due to surface oil sands mining and upgrading activities, and their potential bioaccumulation and tainting of the commercial fishery in the Athabasca River. This includes...
The Athabasca River Basin contains valuable resources including timber, coal, petroleum and natural gas, and oil sands. A variety of intensive development activities are taking place and the use of water in these activities is important. In order to provide the Athabasca River Basin Planner...
