"In the Laurentian Great Lakes, the seismostratigraphy revealed by legacy seismic reflection profiles (i.e., analogue paper records) provides insight to the history of glaciation and deglaciation, sediment deposition and lake level history. Digital recovery and analysis of Great Lakes legacy seismic data is a cost-effective method to generate the offshore broad scale surfaces pertinent to the surficial framework geology layer required as input by three-dimensional stratigraphic studies. This Open File describes the digital recovery of 1566 km of recently discovered single channel seismic reflection data collected in central and eastern Lake Erie in the summer of 1967. The digital outputs are stored on-line in the Geological Survey of Canada-Atlantic (GSCA)"--Introduction, page 1. Lake sediments Erie, Lake. Geology, Stratigraphic.
