Abstract

Measurements were made of the rate of accumulation of sediments in the Saguenay Fjord, Quebec, Canada. The measurements were made from cesium-137 activity in 19 cores. The data varied between sediment rates of greater than 1.0 cm/year upstream and 0.2 cm per year downstream. In cores from the northern basin, the cesium-137 profiles indicate that they follow the pattern of fallouts on the ground, reflecting the impact of a sudden inflow of clay from a major mudslide. In large basins indications are that the rate of sedimentation is less influenced by external happenings. At upstream locations the carbon content and the C/N ratio are higher. Based on cesium-137 dating, core sections show carbon contents that reflect changes caused by the forest industry over the years
