Abstract |
The southwestern shoreline area of Lake Superior is subjected to extensive erosion of glacial-lacustrine red clay deposits. Clay bluff from the shoreline contains a large percentage of clay-size particles which remain suspended in Lake Superior for days to weeks. The clay-size particles undergo solubilization and exchange processes in the lake water. This investigation measures inputs of chemical parameters from clay particles in Lake Superior water as of a function of time. Comparisons of the chemical input magnitudes from shoreline erosion, sediment resuspension, and river particulate transport are made. Monitoring of Bayfield County, Wisconsin streams for sediment transport was done for the spring runoff period. The chemical characteristics of a near-shoreline Lake Superior site was studied as a function of water turbidity. |
