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 dataset is used to display the location of sound velocity profiles collected during USGS Cruise 08016 within the St. Clair River between Michigan and Ontario, Canada, 2008. The information contained within the sound velocity profiles is needed to adequately account for refraction artifacts that may be present within raw swath bathymetric data. This dataset contains hyperlinks to graphs of the sound velocity profile at each station location, as well as location in easting and northing (UTM, Zone 17N, WGS84, meters), latitude, longitude, time of day and date.

Data_Quality_Information:
Logical_Consistency_Report:
All sound velocity profiles were acquired with the same instrument during the course of USGS Cruise 08016; an Applied Microsystems SV plus v2.
Completeness_Report:
All sound velocity profiles collected during USGS Cruise 08016 are included in this ESRI 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 recorded with HYPACK (www.hypack.com). The CSI LGBX Pro received positions from a DGPS antenna located on the port, aft roof of the R/V Rafael cabin. Ship location was used for the sound velocity deployments. The SV plus v2 sound velocity profiler was hand deployed. Once the system reached bottom, positions were read from HYPACK and stored. DGPS accuracy is 1 to 3 meters, depending on the distance from a US Coast Guard coastal repeater station (<http://www.navcen.uscg.gov/>). However, offsets from the location of hand-deployment and the DGPS antenna were not measured. Thus, the horizontal accuracy of the sound velocity locations is considered to be +/- 5 meters.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Water depth of the sound velocity profiles was extracted from the recorded sound velocity profile after recovery. Depth is recorded as the sound velocity profiler is lowered through the water column and downloaded after the instrument is recovered. Data are stored in ASCII text files.

Sound velocity profiles are acquired in order to measure the speed of sound in the water column during survey operations. This information is used to correct any refraction artifacts that may be present within the swath bathymetric data due to unaccounted for changes in the speed of sound throughout the water column. As such, the swath bathymetric acquisition is described here, as well as acquisition procedures for the sound velocity profiles.

Swath-bathymetric and acoustic-backscatter data were acquired with a SEA, Ltd., SWATHplus interferometric sonar operating at a 234-kHz frequency (<http://www.sea.co.uk/swathplus.aspx?nav=products>). The SWATHplus transducer was mounted at the bow of the USGS R/V Rafael. Bathymetric data were acquired over variable swath widths ranging from 10 to 100 m, in water depths of about 1 to 25 m. A total of 109 km of swath bathymetric data were collected.

SWATHplus acquisition software (version 3.05.90) was used to digitally log the bathymetric data at a rate of 30 pings/second and 3,072 samples per swath (ping) in the SWATHplus SXR format. Data collection parameters are saved into a SWATHplus session file in SEA's SXS format. These files can be used for data replay.

An Octopus F180R Attitude and Positioning system (see: <http://www.codaoctopus.com/motion/f180/index.asp>) recorded ship motion (heave, pitch, roll, and yaw). These data were transmitted via network connection to the SWATHplus data collection software. The Octopus F180R Inertial Measurement Unit (IMU) was mounted directly above the SWATHplus transducers, to minimize lever arm offsets that can lead to positioning errors. The F180R uses two L1 antennas for position and heading accuracy. The antennas are mounted on a rigid horizontal pole, 3 meters above the F180R IMU, with a horizontal separation of 1 meter and are offset from the IMU in a forward/aft configuration. The forward offset of the primary antenna from the IMU is 0.5 meters, with no port/starboard offset.

Eight sound-velocity profiles were acquired during survey operations at roughly 4-hr intervals using an Applied Microsystems SV Plus V2 Velocimeter (<http://www.appliedmicrosystems.com/products/productDetails.aspx?id=1>)

Process_Description:
Eight sound velocity casts were collected at roughly 4 hour intervals during USGS Cruise 08016 using an Applied Microsystems SV Plus v2 instrument (see <http://www.appliedmicrosystems.com/products/productDetails.aspx?id=1> for details).

At each station, the SV plus 2 was hand deployed and slowly lowered to the seafloor. The SV plus v2 was monitored by a member of the science party and as the instrument made contact with the seafloor, the position (i.e. location) was recorded in the lab using HYPACK navigation software. The position was then manually recorded within the cruise log and SWATHplus acquisition software. Upon recovery, the SV plus was connected to an onboard computer via serial port in order to download data using the SV plus v2 communications software, SmartTalk.

Process_Description:
The location of each of the fourteen sound velocity profiles was stored in eastings and northings (UTM, Zone 17N, meters, WGS84) in a comma-separated value file (*.csv). This file was reformatted using an GNU awk script and station number, water depth at station taken from the profile, time and date were added.

Proj (version 4.6.1) was used to convert the Eastings and Northings to Latitude and Longitude. GNU awk and paste were used to merge the proj output with the original comma-separated value file (*csv), creating a new csv file containing Latitude, Longitude, Depth, Cast number, Easting, Northing, Julian Day and Time.

Software: GNU awk 3.1.5

The comma-separated text file was then imported to ArcMap 9.2. An event theme was created using Tools - Add XY Data. The projection was defined as UTM, Zone 17N, meters, WGS84. The event theme was then converted to a point shapefile. A hyperlink field was then added to the attribute table of the shapefile in order to link to JPG images of graphs depicting the sound velocity profile at each station.
