Description:
Abstract:
This field activity is part of the effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. This cruise was conducted in collaboration with the Stellwagen Bank National Marine Sanctuary, and the data collected will aid research on the ecology of fish and invertebrate species that inhabit the region. The Sanctuary's research vessel, R/V Auk, visited 75 locations on Stellwagen Bank at which a customized Van Veen grab sampler (SEABOSS) equipped with a video camera and a CTD was deployed in drift mode to collect sediment for grain-size analysis, video imagery of the seabed, and temperature, conductivity, and depth measurements of the water column. Additional information regarding this field activity is available from https://cmgds.marine.usgs.gov/fan_info.php?fa=2015-062-FA.
Purpose:
To provide still images representative of the sea floor that were extracted from video imagery acquired with the SEABed OBservation and Sampling System (SEABOSS). These data provide ground-truth information for geophysical datasets and are used in seabed interpretations. The images have location information in the EXIF header and are also the same as the station locations in the 2015-062-FA_station_data_summary file available from the Larger Work citation.

Data_Quality_Information:
Logical_Consistency_Report:
The image names are in the format staXXXX_Y.jpg where XXXX is the station number and Y is the image number at that station. Each station has 2 images - one showing a broader view of the landscape and the second a close-up of the seabed. These images are from the same camera, the difference in view is related to the closeness of the SEABOSS system to the seafloor. All the images are from one camera except station 4382. Station 4382 images are from a second camera mounted higher on the SEABOSS system because the preferred camera was non-functional. Although the images are not from the exact same location (the two photos from a station), the EXIF header information in each is the same. This is because the video the images were extracted from did not display time. So the navigation fix is based on the station location recorded in the cruise log book. Or the drift line end location recorded in the log book. These fixes may not exactly fall on the video drift line as the video drift line navigation points are extracted from the GPS system based on time. Offsets are a result of rounding error or number of decimal places of the location fix. The 2015-062-FA_station_data_summary (available from the Larger Work citation) station locations are the same as the image locations at each station number.
Completeness_Report:
Each station has 2 images - one showing a broader view of the landscape and the second a close-up of the seabed. With 75 stations, this makes a total of 150 JPEG images.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Although the images do not represent spatial data, the spatial information is available in the EXIF header of each image, which is derived from the station data summary file (available from the Larger Work citation). The location information for stations was acquired from a satellite navigation receiver (Furuno satellite compass SC-30, GPS receiver) at one second intervals with a horizontal accuracy of 10 m. The navigation antenna is located 5.3 m forward of the SEABOSS deployment location. This offset was not accounted for in the navigation acquisition (navigation fixes represent antenna location).

Process_Description:
Seabed video images were collected using a battery-operated, high-definition (1920 x 1080 pixels) GoPro digital video camera mounted on the USGS SEABed Observation and Sampling System (SEABOSS). The SEABOSS system actually had two GoPro cameras attached to it - with the second camera mounted a little higher on the frame which only shows a partial view of the seabed. This second camera was used only to observe obstacles, like gill nets and lobster gear, in order to avoid entanglement. Or, in the case of station 4382, provide a backup system if the primary camera failed.
As the SEABOSS drifted over the seabed, the forward-looking camera imaged the seabed at a rate of 60 frames per second from an altitude of ~1 meter. Lighting was provided by two, battery-operated Keldan LED video lights. Each light provided a light flux of up to 9000 lumens at a correlated color temperature of 5000 kelvins. Two parallel red lasers mounted 20 centimeters apart provided a scale in the video images.
Video imagery includes the launch and recovery of the SEABOSS, transit through the water column, and the drift over the seabed. The duration of individual video files ranges from 4 to 12 minutes. Video files are archived in .MP4 format and range in size from 0.9 to 2.6 gigabytes. These video files are not available as part of this data release.
Video files are archived at the USGS Woods Hole Coastal and Marine Science Center, 384 Woods Hole Road, Woods Hole, MA 02543.

Process_Description:
Video frame-grab images were extracted from high-definition (1920 x 1080 pixels) GoPro digital video by reviewing the video from each station and saving a frame-grab image that clearly showed the seabed. These images were obtained using open source VLC Media Player software (version 2.0.0) developed by the VideoLAN project. http://www.videolan.org/vlc/index.html
Two video frame-grab images are provided for each station. One image (staxxxx_1.jpg) shows a broad view of the landscape as the SEABOSS drifted over the seabed. The second image (staxxxx_2.jpg) shows a close-up of the seabed as the SEABOSS was stationary during the collection of the sediment sample. The xxxx is the station number. Where visible, the two parallel red lasers mounted 20 cm apart provide a scale.

Process_Description:
Using the AUK2015062_station_data_summary.csv, the approximate time and location of each photo was derived. The station location (latitude and longitude), date and time for each station was extracted from the CSV file. This information was reformatted using an awk script so that the following columns of information were available: image name (based on the station number), julian day, GPS date (in the format YYYYMMDD), GPS time (in the format HH:MM:SS), latitude, and longitude. This information was written to a CSV file - 2015-062-FA_image_locations.csv. This process step and subsequent process steps (unless otherwise noted), were performed by the same person - VeeAnn A. Cross.

Process_Description:
A python script (writeexif_2_readfile_11_24_15.py executed with IDLE version 2.7.3) was then run that incorporated the information from 2015-062-FA_image_locations.csv, along with additional information, into the appropriate locations in the EXIF header of each GoPro grab image at each station. Although the two images from each station aren't from exactly the same place, the same information for that station was populated in each photo.The PYTHON script uses ExifTool (version 9.4.6.0) to write the information to the image headers of the full-resolution images. The following tags were populated in the JPEG image headers. Information is duplicated in some tags. This was done because different software packages access different tags.

GPS tags: The values populated are unique for each image and based on the information exported from the photo locations shapefile.

To extract the information from the image headers using ExifTool, the following command can be used (tested with ExifTool version 9.4.6.0):

exiftool.exe -csv -f -filename -GPSTimeStamp -GPSLongitude -GPSLatitude -n -Artist -Credit -comment -keywords -Caption -Copyright -CopyrightNotice -Caption-Abstract -ImageDescription *.jpg > out.csv

The -csv flag writes the information out in a comma-delimited format. The -n option formats the latitude and longitude as signed decimal degrees.
