Video data were collected over 3 days between September 6 and September 9, 2014 using a towed camera sled system. 11.6 hours of video were collected along 18 transects; the mean length of time per transect was 38 minutes. Video operations were conducted by deploying up drift of a target and drifting over it at speeds of 1 knot or slower. The video data were collected in order to ground truth geologic and habitat interpretations of sonar data collected during the same field activity. The video-survey locations were chosen after the sonar mapping to investigate sea-floor features of interest, including bathymetric features such as ridges and depressions, areas that represent the spectrum of backscatter intensity observed in the survey area, and areas that represent the spectrum of water depths surveyed. The camera sled was equipped with both vertical-downward and adjustable oblique-forward facing HD video cameras. Paired lasers set a fixed distance apart are visible in the video and are used to scale features on the seafloor. A fiber optic cable was used to allow real-time on-board viewing of both camera feeds. The sled was also equipped with a forward-scanning sonar system for collision avoidance. Conductivity and temperature were continuously recorded using a SeaBird Seacat 37-SM. Depth and altitude were measured to aid operations but not recorded. A downward facing still camera, designed for small invertebrate identification, was attached to the sled, but insufficient lighting rendered the still images unusable. Real-time observations of the major and minor substrate type were made, as well as occasional comments about organisms, features, or objects of interest. Purpose: These data are intended for science researchers, students, policy makers, and the general public. These data are not intended to be used for navigation.

Lineage: Process_Step: Process_Description: Video was collected over 3 days using a towed camera sled. The camera sled has downward and adjustable oblique-forward facing HD video cameras. There were 18 video transects; 11.6 hours of video were collected; the mean length of time per transect was 38 minutes. Video operations were conducted by deploying up drift of a target and drifting over it at speeds of 1 knot or slower. Raw video was recorded in nanoFlash MXF digital files. GPS data was encoded and recorded onto the audio track of the video files using RedHen VMS hardware. Process_Date: 2014 Process_Step: Process_Description: MXF video files were converted to MPEG-2 encoded mpg container digital files using FFmpeg for further processing byRedHen software. Process_Date: 2014 Process_Step: Process_Description: The MPEG-2 video files were converted to MPEG-4 encoded mp4 container digital files using FFmpeg. This allowed the mp4 video files to have a subtitle track containing navigation added to the file. The subtitle tracks were generated using the navigation output from the GPS encoded audio tracks, and they display the date, time, latitude and longitude of video recording; subtitles are updated in the video every second. Process_Date: 2017 Process_Step: Process_Description: Edited metadata to add keywords section with USGS persistent identifier as theme keyword. No data were changed.
