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 includes the locations, identifiers, grain-size descriptions of surficial sediment samples collected at 13 stations within the St. Clair River between Michigan and Ontario, Canada during USGS Cruise 08016. The sediment samples were collected in order to ground-truth geophysical data and characterize the surficial sediment distribution of the riverbed.

Data_Quality_Information:
Logical_Consistency_Report:
All sample data were collected with the mini-SEABOSS (SEABed Observation and Sampling System) by the U.S. Geological Survey within the St. Clair River between Michigan and Ontario, Canada in 2008. The mini-SEABOSS is configured with a Van-Veen grab sampler to collect sediment samples of the riverbed.
Completeness_Report:
Fifteen sample locations were occupied, however sediment samples were collected from only thirteen locations. Two locations contained primarily coarse grained sediment (gravel and/or cobble) and were too coarse to successfully sample with the mini-SEABOSS. Samples were attempted, but any sediment washed out before the instrument could be retrieved.

Sample, photographic and video navigation for locations 1, 2 and e (up to time: 13:31) used navigation from the video time stamp, as navigation was not recorded in HYPACK. HYPACK navigation was available for sample 3 location.

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. The CSI LGBX Pro received positions from a DGPS antenna located on the port, aft roof of the R/V Rafael cabin. DGPS positions were recorded within HYPACK (www.hypack.com) navigation software. Offsets between the DGPS antenna and the mini-SEABOSS were not measured. 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, the horizontal position of the mini-SEABOSS during sample collection is assumed to be +/- 10 meters at best, due to a lack of precise positional data at the time of sample recovery.

Source_Contribution:
Video and digital photographs were collected at 37 stations using the USGS Mini SEABOSS (Blackwood and Parolski, 2001). Mini SEABOSS stations were selected based on preliminary acoustic-backscatter mosaics, with the objective of characterizing broad areas of different backscatter intensity. With the Mini SEABOSS deployed, the research vessel was allowed to drift with occasional power from the vessel to control drift direction. Continuous video was collected over a total of 11.5 km of lake and riverbed. Video drift position was derived from the HYPACK® navigation files based on the start and end times of the drift. For some portions of the drift, there was no navigation, so the position was derived from the time and position stamp in the video at 30-s intervals.

The mini-SEABOSS is housed with a Minolta CO., LTD, DiMAGE 7Hi camera. The full resolution of the acquired images is 2560 x 1920 pixels.

Grab samples of the surficial sediment were collected at 15 stations, typically at the end of a drift. The upper 2 cm of sediment was scraped from the surface of the sample for texture analysis. Sediment samples were collected at locations with relatively fine-grained sediment (sand or mud). Samples were not collected in gravel or cobble areas where gravel prevented full closure of the sampler and resulted in a washed-out sample.

A total of 13 bottom samples were submitted for grain-size analysis. Two partially recovered, washed-out samples were not submitted. Grain-size analysis was performed at the USGS Sediment Laboratory at WHCMSC using methods described by Poppe and others (2005).

Process_Description:
Grab samples were collected with the mini SEABOSS (Blackwood and Parolski, 2001) at thirteen stations within the St. Clair River. Fifteen locations were occupied, but samples were successfully collected at thirteen; two locations were too coarse to sample. The upper 2 cm of sediment was scraped from the surface of the sample for texture analysis. Thirteen samples were submitted for grain-size analysis at the USGS Sediment Laboratory at the Woods Hole Coastal and Marine Science Center using methods described by Poppe and others (2005).

Sample locations for sample 1 and 2 were read from the video time stamp, as HYPACK navigation was not available. The position information at the end of the video drift was used as position of the sample. (Samples were acquired at the end of video drifts).
