Abstract

Palaeolimnology is the reconstruction of past environments using information recorded in lake sediments, including preserved biological organisms and chemical indicators. A key assumption of palaeolimnology is that undisturbed lake sediments may provide a faithful, continuous record of change over long time periods, ranging from years to millennia. Using proven methods available for dating lake sediments, both the continuity of the record and the dates of recorded changes may be established. Palaeolimnology has been widely employed across the world, for example in reconstructing past climate over thousands of years and for the study of pollutant impacts over the last 200 years following the Industrial Revolution. It is particularly well suited to the study of pollution arising from fossil fuel combustion because several indicators of pollutant inputs and biological changes may be recorded. The main purpose of this study was to employ various palaeolimnological techniques to establish whether there have been chemical or biological changes in lakes in Northern Alberta as a result of the industrial activities associated with exploitation of the Athabasca Oil Sands.
