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.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 a grid representing elevation of the bedrock surface within the St. Clair River between Michigan and Ontario. These data are used to assess the relation between geologic Framework and morphologic changes in the St. Clair River channel.

Data_Quality_Information:

Logical_Consistency_Report:

The Boomer unique shot-point navigation and the Boomer SEG-Y data were evaluated during processing to eliminate spurious navigation and to assess the quality of the sub-bottom profiles.

Completeness_Report: All Boomer seismic data were used to generate this grid.

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 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 (<http://www.navcen.uscg.gov/>). Error in horizontal position is introduced due to uncertainty in the measurement of layback of the seismic source. Overall horizontal accuracy is assumed to be on the order of 5 meters.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

The nominal resolution of the Boomer system is 1 meter. The vertical resolution of the bathymetric grid used in generating bedrock elevation is 0.5 m (referenced to IGLD 85). Overall vertical accuracy is assumed to be +/- 1 meter.

Lineage:

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 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 as seconds of arc. The layback distance from the DGPS antenna to the source and receiver was visually 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, latitude, year, filename, Julian day, and time of day (UTC). Latitude and longitude were converted from geographic coordinates (WGS84) to UTM zone 17 coordinates (WGS84) using Proj (version 4.6.0). The unique shot navigation for each seismic line was then concatenated into a comma delimited (.csv) text file.

Process_Description:

Isochron points were imported into Dynamic Graphics, Inc. EarthVision surface modeling software. The data points were gridded at a 20 x 20-m cell size. The isochron grid was then converted to thickness in meters using a constant sediment velocity of 1,650 m/s. A 5-m bathymetric (referenced to IGLD 85) grid derived from our swath bathymetric data was added to the total sediment isopach grid to yield elevation (IGLD 85) grid of the bedrock surface. Elevation of the bedrock surface was exported as X (easting), Y (northing), and Z (meters) points.

Fees: none

Technical_Prerequisites:

The grid contained in the dsuelev.zip file is available as an ESRI Binary grid and an ASCII grid with an ESRI header. However, the folder structure within dsuelev.zip is critical to proper use of the ESRI binary grid.

To utilize these data, the user must have a GIS software package capable of reading ESRI Binary grids or ASCII grids with ESRI headers, or be able to manipulate an ASCII matrix with a geospatial header. The ASCII raster files can be easily converted to ESRI grid format in either ArcView with Spatial Analyst extension (Import Data Source: ASCII Raster) or ArcGIS with Spatial Analyst extension (ASCII to Raster). The user should select floating point grid (as opposed to integer grid) when converting the data.
