Digital video was collected in September 2014 in the mouth of the Columbia River, USA, as part of the U.S. Geological Survey Coastal and Marine Geology Program contribution to the Office of Naval Research funded River and Inlets Dynamics experiment (RIVET II). Still images were extracted from the underwater video footage whenever the camera was resting on the sediment bed and individual sediment grains were visible and in focus. The images were used to calculate the calibration curve through auto-correlation regressed against the results of laboratory-determined median grain size (D50) of the grab samples (Barnard, 2007), provided in an accompanying .csv file. Purpose: The imagery was collected to aid in the collection of high spatial resolution grain size data over individual subaqueous bedforms.

Logical_Consistency_Report: Data are logically accurate Completeness_Report: Data represent ground conditions of the mouth of the Columbia River only along individual tracklines where data were collected. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The positions of the data reflect the position of the GPS antenna on board the boat when data were collected and not the real location of the digital camera. Positional data in this report were not corrected for layback and thus represent only approximate locations. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: A formal accuracy assessment of the vertical positional information in the dataset has either not been conducted, or is not applicable. Lineage: Process_Step: Process_Description: Video footage was converted from video type .MXF to a Red Hen System compatable format of .AVI using the software Acrok MXF Converter. All image and sound quality were maintained at the original video's quality. Process_Date: 20150612 Process_Step: Process_Description: Video footage was indexed using Red Hen System's proprietary software IsWhere. An XML format metadata file was produced from each video and includes GPS information intermittently through the video of: latitude (decimal degrees), longitude (decimal degrees), GPS altitude (meters), video time (HH:mm:ss:ms), Dublin Julian Date in UTC (julian date = timeCode+2415020), course direction (degrees), speed (meters/second). Process_Date: 20150612 Process_Step: Process_Description: Geotagged images were grabbed from the video every 0.5 second. From this set of evenly timed images, images were chosen when the sediment was in focus and the camera was resting on the bed. This process resulted in there being multiple images for each location. The image files contain the GPS location in lat/lon decimal degrees. Process_Date: 20150612 Process_Step: Process_Description: Each image is named based on the video it was taken from, followed by the time stamp in the video. For example image "0205301_0_1_41_0" is from video 0205301 at time 00:01:41:00 (HH:mm:ss:msms). Process_Date: 20150612 Process_Step: Process_Description: One to two images were chosen from each videoed location within each sediment sample. This resulted in 3 to 10 images corresponding with each sediment grab sample. Process_Date: 20150612 Process_Step: Process_Description: Each image had its auto-correlation coefficient calculated for pixel offset values of 1 through 20. The resulting correlation curves were averaged together for images taken from the same sediment sample, and across sediment samples which were determined to have a difference in D50 less than 0.05 mm. Process_Date: 20150612 Process_Step: Process_Description: The auto-correlation coefficient value at a pixel offset of 5 was extracted from each curve. These values were plotted against the Beckman Coulter laser diffraction determined D50. A least squares fit was applied to these data to obtain a calibration curve of auto-correlation offset with D50.
