Irwin 2010 1.0 online Open-File Report 2010-1035 Reston, VA U.S. Geological Survey https://pubs.usgs.gov/of/2010/1035/ 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. This data set contains shot-point navigation for approximately 58 km of Boomer data collected by the U.S. Geological Survey during cruise 08016 within the St. Clair River between Michigan and Ontario, Canada, 2008. Shot point navigation is provided to correlate with JPEG images of the collected Boomer data. 20080531 20080601 ground condition Complete None planned -82.427022 -82.401964 43.015350 42.955883 USGS Metadata Identifier USGS:11e55f88-579a-44a3-89ac-80a18bd2a253 None U.S. Geological Survey USGS Woods Hole Coastal and Marine Science Center WHCMSC Coastal and Marine Geology Program CMGP seismic Boomer sub-bottom profiler shot-point navigation WHCMSC field activity serial number 08016 ESRI Shapefile USGS R/V Rafael ISO 19115 Topic Category geoscientificInformation inlandWaters USGS Thesaurus navigational data geophysics geospatial datasets None North America United States Michigan Great Lakes Upper Great Lakes Lake Huron St. Clair River Upper St. Clair River Canada Ontario None Public domain data from the U.S. Government are freely redistributable with proper metadata and source attribution.

The unique shot navigation data were evaluated during processing for spurious points; all spurious points were removed prior to generating the trackline navigation. Shot point navigation for all Boomer seismic data were used to generate this shapefile 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/>). The seismic reflection profiling system utilized a Boomer energy source operated with a power output of 175 joules. The Boomer source was fired 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. 2008 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, latitude, year, filename, Julian day, and time of day (UTC). A scalar was applied to convert geographic coordinates stored in arc seconds, (WGS84) 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. 2008 U.S. Geological Survey Dave Foster Geologist mailing and physical address

The event theme was then saved to a point shapefile and the projection was defined as Geographic Coordinate System, WGS84 (GCS_WGS_1984). The point shapefile was visually inspected for spurious data points and these data points were manually deleted. 2008 Dave Foster U.S. Geological Survey Geologist mailing and physical address

Woods Hole MA 02543 USA 508-548-8700 x 2311 508-457-2310 jdenny@usgs.gov Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). The link to the data in the Identification_Information section had to be fixed. The link to the data in the Distribution_Information section had to be fixed. The link to the browse graphic had to be fixed. Attempted to modify http to https where appropriate. Reordered the links in the identification section to have a landing page link as the first link. Moved the minimal source information provided to make it the first process step. The distribution format name was modified in an attempt to be more consistent with other metadata files of the same data format. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent. 20171018 U.S. Geological Survey VeeAnn A. Cross Marine Geologist Mailing and Physical
