WHSC/SFMG will map the geologic framework of the upper St. Clair River and surficial geology of the river/lake bed. Stratigraphic mapping will include depth to bedrock and the stratigraphy of Quaternary glacial and post glacial deposits. Surficial mapping will delineate sediment texture and morphology of the river/lake bed. The geologic framework will support ongoing studies that are quantifying changes in river bed elevation, specifically, identifying the extent of river bed erosion. Geophysical systems will be deployed to acoustically image the geologic framework. Video, photography and sampling of the river bed will be used to verify the surficial geologic interpretation.

Summary
Data were collected over a five day period. Data include seismic reflection profiles: 79.8 km of 3.5 kHz Chirp data recorded in SEG-Y format, 58.5 km of Boomer seismic reflection profiles recorded in SEG-Y format, 79.8 km of Submetrix bathymetric data, 79.8 km of Klein sidescan sonar data in XTF format, 453 digital bottom photographs in JPEG format, 310 minutes of bottom video, and 17 bottom sediment samples.
