Abstract
Samples of Lake Erie sediment collected in 1964, 1965, 1966, and on a monthly basis from May, 1967 through November, 1968, were analyzed for total phosphate, iron and organic carbon. Samples were collected by means of a core technique. The cores were sectioned at 2.5 cm intervals and each of the six sections were analyzed for the same factor. Results of the analyses showed only a slight increase in phosphate since 1964. However, all those factors showed a definite increase from May, 1967 through November, 1968. The two sampling methods yielded slightly different results. The sediment was found to consist of two distinct layers, with the upper 5 cm of sediment being usually higher in concentrations of materials than the lower portion. (Author)
