Description:

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:

This data set contains shot point navigation at 100 shot intervals for approximately 80 km of Chirp data collected by the U.S. Geological Survey during cruise 08016 within the St. Clair River between Michigan and Ontario, Canada, 2008. The shot point data are provided to correlate with the JPEG images of seismic profiles.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

All attributes were evaluated during processing as standard quality control to ensure attributes contain accurate and relevant information and values.

Logical_Consistency_Report:

Seismic shot-point navigation was generated from unique shot navigation for the seismic system. The unique shot navigation data were evaluated during processing for spurious points; all spurious points were removed prior to generating the trackline navigation. The unique shot point navigation was downsample to produce the 100 shot point navigation.

Completeness_Report:

Valid shot point navigation at 100-shot intervals for all Chirp seismic data were used to generate this shapefile.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

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 Knudsen acquisition software, SounderSuite, where Chirp sub-bottom data with a peak frequency of 3.5 kHz were recorded in Society of Exploration Geophysicists Y (SEG-Y) format (Barry and others, 1975) with DGPS 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 Chirp sub-bottom profiler was deployed off the starboard side of the USGS R/V Rafael. Chirp sub-bottom profiles were collected using a dual-frequency (3.5 and 200 kHz) Knudsen Engineering Limited (KEL) Chirp 3200® system (Knudsen Engineering Limited, 2009). The single-beam water depths from the 200-kHz channel were logged together with navigation in ASCII format. Chirp sub-bottom data with a peak frequency of 3.5 kHz were recorded using Knudsen acquisition software, SounderSuite, in Society of Exploration Geophysicists Y (SEG-Y) format (Barry and others, 1975) with DGPS navigation logged to the SEG-Y file trace headers. The Chirp system was fired at a rate of 0.25 or 0.5 s. The trace length was set to 67 ms. The vertical resolution of this system is approximately 30 cm. A total of 80 km of sub-bottom data were collected

Process_Step:

Process_Description:

A script was executed using Seismic Unix (version 4.1) to read the 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). Geographic coordinates in arc seconds (WGS84) were converted to UTM zone 17 coordinates (WGS84) using Proj (version 4.6.0).Before saving the header information to a text file, the data were filtered using AWK (no version) to save only intervals of every 100 shot point locations retaining the last shot of each line. The 100 shot interval navigation for each seismic line were then concatenated into a comma delimited (.csv) text file.

Process_Description:

The text file (*.csv) was imported into ESRI ArcMap 9.2 using Tools - Add XY Data and converted to an event theme. 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.
