The regional lake sediment and water survey of the north shore of Lake Superior area, Ontario (NTS 41K and 41N) was conducted during the summer of 1978.
This report presents analytical and statistical data for 12 variables in lake sediments and three variables (U, F, pH) in lake waters from 685 sample sites, collected at an average density of one sample per 14.0 km².
