Description:

Abstract:

This dataset includes 2,523 still images extracted from geo-referenced digital video imagery of the seafloor at the mouth of the Columbia River, OR and WA, USA, along with grain size analysis of the surface sediment. Underwater 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 are used to calculate the median grain size through an auto-correlation method (Barnard and other 2007), and are provided in an accompanying .csv file.

Purpose:

The imagery was collected to obtain high spatial resolution grain size data over individual subaqueous bedforms.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Accuracy of dataset attribute information was deduced to be good based both on visual examination of still images, video imagery, navigation trackline location on agreement with observer's field knowledge.

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 camera in the water. 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 was not been conducted, nor is it 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 bed 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 given a file name 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:ms).

Process_Date: 20150612

Process_Step:

Process_Description:

The UTC time of each image was calculated by extracting the UTC time at the beginning of the video from the XML file produced by IsWhere for each video file, and adding the time stamp of the image. These values are recorded in Julian time in the UTC time zone in the provided spreadsheet. The lat/lon values were converted to UTM zone 10N, WGS84 coordinates using the matlab tool "deg2utm" version Aug/06, available at mathworks.com, and recorded in the provided spreadsheet.

Process_Date: 20150612

Process_Step:

Process_Description:

The median grain size of sediment shown in each image was estimated using an auto-correlation process and calibration images, which are available in "child-item title", included with this publication.
