| Abstract | 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. |
| Summary | (Plain Language Summary, not published)
This Open File report contains data for the location, description, and interpretation of sediment samples from all of Lake Erie, one of the Laurentian
Great Lakes. Grain size and carbonate content data for some of the samples are included. Dive observations at some sample stations showed that the surface of glacial sediments is covered with a rippled sand and gravel lag. Sediment cores, some
boreholes, and acoustic profiles were collected to provide information on the layering of the offshore finer-grained sediment units, and the depth to glacial sediments. The acoustic profiles were combined with lower frequency seismic reflection
traverses to provide cross-sections of interpreted bedrock surface and sediment configuration beneath Lake Erie. |
