Contents

This Open File report contains Excel files and map figures with setting and background information for the location, description, interpretation, and some grain size and carbonate content data for sediment samples from Lake Erie, one of the Laurentian Great Lakes. The samples were obtained during the early 1960s and 1970s in surface grabs, cores and boreholes. Dive observations of  lake bed conditions were obtained at some sample stations. Acoustic profiles collected at 14.25 kHz during the sampling and coring expeditions provided information on the stratigraphy of the offshore finer-grained sediment units, and the depth to glacial sediments. Selected echogram profiles are compared with cored sediment sequences and other profiles are combined with lower frequency seismic reflection traverses to provide cross-sections of interpreted bedrock surface and sediment configuration beneath Lake Erie
