Abstract:
In 2008, the U.S. Geological Survey (USGS), Woods Hole Coastal and Marine Science Center (WHCMSC), in cooperation with the U.S. Army Corps of Engineers conducted a geophysical and sampling survey of the riverbed of the Upper St. Clair River between Port Huron, MI, and Sarnia, Ontario, Canada. The objectives were to define the Quaternary geologic framework of the St. Clair River to evaluate the relationship between morphologic change of the riverbed and underlying stratigraphy. This report presents the geophysical and sample data collected from the St. Clair River, May 29-June 6, 2008 as part of the International Upper Great Lakes Study, a 5-year project funded by the International Joint Commission of the United States and Canada to examine whether physical changes in the St. Clair River are affecting water levels within the upper Great Lakes, to assess regulation plans for outflows from Lake Superior, and to examine the potential effect of climate change on the Great Lakes water levels ( <http://www.iugls.org>). This document makes available the data that were used in a separate report, U.S. Geological Survey Open-File Report 2009-1137, which detailed the interpretations of the Quaternary geologic framework of the region. This report includes a description of the suite of high-resolution acoustic and sediment-sampling systems that were used to map the morphology, surficial sediment distribution, and underlying geology of the Upper St. Clair River during USGS field activity 2008-016-FA . Video and photographs of the riverbed were also collected and are included in this data release. Future analyses will be focused on substrate erosion and its effects on river-channel morphology and geometry. Ultimately, the International Upper Great Lakes Study will attempt to determine where physical changes in the St. Clair River affect water flow and, subsequently, water levels in the Upper Great Lakes.
Purpose:
JPEG images of each seismic profile were generated in order to incorporate images of the seismic data into Geographic Information System (GIS) projects and data archives utilizing HTML. These JPEG images represent approximately 58 km of Boomer seismic data collected in 2008 during USGS cruise 08016. This format is universal and yields an easily viewable image of the seismic profiles. Each profile image is hyperlinked to its corresponding trackline navigation contained within a polyline shapefile (08016_Boomer_trk.shp), shot-point locations are available in a point shapefiles (08016_Boomer_sht.shp). These data are available in an ESRI ArcMap project, as well as separate .zip archives (<https://pubs.usgs.gov/pubs/of/2010/1035/gis_catalog/>).

Horizontal_Positional_Accuracy_Report:
Differential Global Positioning System (DGPS) navigation data were acquired with a Communications Systems International (CSI), Inc. LGBX Pro receiver and sent to Boomer acquisition software, SonarWiz, where sub-bottom data were recorded in Society of Exploration Geophysicists Y (SEG-Y) format (Barry and others, 1975) with DGPS positions logged to the SEG-Y trace headers.

DGPS accuracy is 1 to 3 meters, depending on the distance from a US Coast Guard coastal repeater station (<http://www.navcen.uscg.gov/>). DGPS accuracy is 1 to 3 meters, depending on the distance from a US Coast Guard coastal repeater station (<http://www.navcen.uscg.gov/>).

Source_Information:
Source_Contribution:
The seismic reflection profiling system utilized a Boomer energy source operated with a power output of 175 joules. The Boomer source was fires at 0.5 s intervals. A single-channel Benthos AQ4 streamer received the seismic reflection signal. The analog signal was band-pass filtered between 100 and 3000 Hz. A 23-db gain was applied. The analog signal was digitized and recorded in SEG-Y format using SonarWiz.MAP +SBP software version 4.03.0089. DGPS coordinates were recorded in the SEG-Y file trace headers. The layback distance from the DGPS antenna to the source and receiver was estimated and applied to the position during acquisition. A total of 200 ms of data were acquired for each trace. A total of 58.5 km of Boomer profiles were collected.
Process_Step:
Process_Description:
A Sioseis (<http://sioseis.ucsd.edu/>) script was executed to read the raw SEG-Y (Barry and others, 1975) files, apply a band-pass filter of 500 to 2000 Hz and Automatic Gain Control with a window length of 20 ms. Seismic Unix (version 4.1; Stockwell, 1975) was used to read the processed SEG-Y files, write a Seismic Unix file, and extract SEG-Y trace header information, which included shot number, longitude (arc seconds), latitude (arc seconds), year, filename, Julian day, and time of day (UTC). A scalar was applied to convert geographic coordinates from arc seconds to decimal degrees (WGS84) and then to UTM zone 17 coordinates (WGS84) using Proj (version 4.6.0). The unique shot navigation for each seismic line were then concatenated into a comma delimited (.csv) text file.

Process_Description:
A C-Shell script using Seismic Unix (version 4.1) to read the SEG-Y files and plot the data as 8-bit gray scale Postscript files using the Seismic Unix 'psimage' algorithm was then executed. All images were created with a horizontal scale of 40 traces per inch. The profiles contain 80 milliseconds of Two-Way Travel Time within an 8-inch vertical window, yielding 10 milliseconds per inch. Postscript images were converted to JPEG format using the UNIX ImageMagick (version 5.5.6).

Software: Seismic Unix 4.1, ImageMagick 5.5.6
