This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000001. Longitudes are given to the nearest 0.000001. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is D_WGS_1984.
The ellipsoid used is WGS_1984.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257224.
Sequential unique whole numbers that are automatically generated.

This data set includes the bottom video transects and links to the bottom video (MP4 format) collected within the St. Clair River between Michigan and Ontario, Canada during USGS Cruise 08016. The bottom video transects were collected to ground-truth the geophysical data collected and to characterize the surficial sediment along the riverbed.
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).
Sample locations for sample 1 and 2 were read from the video time stamp, as HYPACK navigation was not available.

The point shapefile was used as an input for a VACExtras (version 1.8), a VB collection of tools developed by VeeAnn Cross (USGS-WHCMSC), which converts point data to a new polyline shapefile, based on the order of records contained within one attribute field.
A 'length' field was added to the attribute table using XTOOLS 6.2.0. Length is stored in meters.
A 'hyperlink' field was added to the attribute table and used to hotlink to the bottom photos.

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.
Video transects were collected at 37 locations using the USGS Mini SEABOSS (Blackwood and Parolski, 2001).
Sample, photographic and video navigation for locations 1, 2 and (up to time: 13:31 for location 3) used navigation from the video time stamp, as navigation was not recorded in HYPACK. HYPACK navigation was available for bottom sample 3 location and from 13:31 to the end of file for photographs and video at location 3.
All bottom video 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.
