Depositional history of sediment in Great Slave Lake : spatial and temporal patterns in geochronology, bulk parameters, PAHs and chlorinated contaminants / by Marlene S. Evans et al. Edmonton - Alberta : Northern River Basins Study 1996. xi, 173p. : graphs, maps, references, tables ; 28 cm. Northern River Basins Study project report 1192-3571 No. 99 "The primary objective of this study was to collect and analyze surficial sediments and high quality, well-described sediment cores for use in defining the depositional history of sediment-bound contaminants in the west basin of Great Slave Lake. The analysis would include those contaminants which have known atmospheric or upstream point sources. Dating of the cores was accomplished by using the lead (210Pb) and cesium (137Cs) methods, and procedures used by two different laboratories were compared. These geochronological results were used to determine sedimentation rates and time scales, and the suitability of the cores for subsequent contaminant analyses."--Study perspective.
