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 13 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 measurements of water column properties.
Purpose:
To provide images of the sea floor acquired with the SEABed OBservation and Sampling System (SEABOSS). These data provide ground-truth information for geophysical datasets and are used in seabed interpretations.

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 (Y=1) and the second a close-up of the seabed (Y=2). The difference in view is related to the closeness of the SEABOSS system to the seafloor. The two images from a station are not from the same geographic location on the video drift, but the EXIF header information in each is the same. This is because the video source imagery did not display time. So the latitude and longitude of the two images is based on the station location time recorded in the cruise log book (the location of a sediment sample; or if no sample collected, the video drift end location). The latitude and longitude position of a station recorded in the log book was adjusted by reference to the latitude and longitude recorded at that time in the GPS navigation file. The 2017-009-FA_station_data_summary (available from the Larger Work citation) station locations are the same as the image locations at each station number.
Some of the images have a green tint to them. This is due to the ambient light in the shallow water.
Completeness_Report: All stations have 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 two 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 had two GoPro cameras and a Seaviewer camera attached to it. The Seaviewer camera had a live feed to the surface and was used only to observe obstacles, like gill nets and lobster gear, in order to avoid entanglement. In the case of camera failure, the additional cameras provided backup video. As the SEABOSS drifted over the seabed, the cameras 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 6 to 12 minutes. Video files are archived in .MP4 format and range in size from 1.4 to 2.7 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 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) shows a broad view of the landscape as the SEABOSS drifted over the seabed. The second image (staxxxx_2) 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 2017-009-FA_station_data_summary.csv, the approximate time and location of each photo was derived. The station location (lat/lon), date and time for each station was extracted from the CSV file. This information was reformatted using an awk script (awkphoto_2017-009-FA on a machine running Cygwin) so that the following columns of information were available: image name (based on the station number), latitude, longitude, GPS time (in the format HH:MM:SS), and GPS date (in the format MMMYYDD). This information was written to a CSV file - 2017-009-FA_image_locations.csv

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 2017-009-FA_image_locations.csv, along with additional information, into the appropriate locations in the EXIF header of each GoPro 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.

GPSLongitude
GPSTimeStamp
GSPDateStamp

JPEG tags: The tag is listed along with the information used to populate it.

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.
