This data set contains a grid representing the thickness of Quaternary undifferentiated glaciofluvial, glaciolacustrine, fluvial, and lacustrine deposits 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.
Chirp sub-bottom profiles were collected using a dual-frequency (3.5 and 200 kHz) Knudsen Engineering Limited (KEL) Chirp 3200 system. Chirp sub-bottom data with a peak frequency of 3.5 kHz were recorded in SEG-Y format 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. A total of 80 km of Chirp sub-bottom data were collected.

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.
The nominal resolution of the Boomer and Chirp sub-bottom profiling systems are on the order of 1 meter and 0.3 meters, respectively. Additional error may be introduced due to the uncertainty of the two-way travel time to depth conversion (assumed to be << 1 meter).
All Boomer seismic data were used to generate this grid, supplemented with Chirp seismic data that coincides with the Boomer data.
This isopach map was generated from Chirp and Boomer sub-bottom data collected within the St. Clair River in 2008.

The grid contained in the qu.zip file is available as an ESRI Binary grid and an ASCII grid with an ESRI header. However, the folder structure within qu.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.
