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 41 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:
Photos were collected of the sediment sample in the grab sampler to document the texture of the seabed surface, the degree of disturbance during sampling, biological features such as worm tubes, and to estimate the volume of sediment collected.
Supplemental_Information:
Additional information regarding the field activity can be obtained from https://cmgds.marine.usgs.gov/fan_info.php?fan=2016-038-FA . The grain-size analyses of the sediment samples collected during this field activity is available in a separate publication (Valentine and Cross, 2019; link available from the cross-reference citation).

Data_Quality_Information:
Logical_Consistency_Report:
The image names are in the format: staXXXX_Y.JPG. The designation XXXX is the station number; Y represents R or L, the right- and left-hand sides of the sample surface in the grab sampler. Each sediment sample has two images - one showing the sediment surface in the right-hand side of the sampler, and the other showing the sediment surface in the left-hand side of the sampler. The clock on the camera was not perfectly synced to the GPS time, so the GPSTimeStamp value in the EXIF header will not match the time portion of the DateTime, DateTimeOriginal, or DateTimeDigitized elements in the EXIF header.
Completeness_Report:
Sediment samples were collected at 30 of the 41 stations visited for analysis. Three additional stations collected samples that were too small to be retained for grain-size analysis, but do have photos. Sediment samples have a maximum of two images - one showing the sediment surface in the right-hand side of the sampler, and the other showing the sediment surface in the left-hand side of the sampler. One station (4543) only has one image (for the right side). No sample was present on the left side. Still images were also collected of some samples (stations 4521, 4543, 4557) that were too small to be retained for grain-size analysis. There are a total of 65 images.
Positional_Accuracy:
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 SEABed Observation and Sampling System (SEABOSS) deployment location. This offset was not accounted for in the navigation acquisition (navigation fixes represent antenna location). The location information in the EXIF header of each image does not represent the exact location where the image was taken; rather each image was given the latitude and longitude of the station location (the location of a sediment sample).

Process_Step:
Process_Description:
Still images of the sediment sample surfaces were collected using a hand-held Nikon 7100 digital camera with a resolution of 24 megapixels (4000 x 6000 pixels), with an 18-200x zoom lens with an aperture ranging from f3.5 to f5.6. After retrieval of the SEABOSS and placement on its wooden stand, the two doors (right and left) on the top of the Van Veen grab sampler were opened and a photo was taken of the sediment surface in each side of the sampler bucket. The centimeter scale in the image allows measurement of the distance from the top of the grab bucket to the top of the sediment surface and provides a qualitative measure of the volume of sediment collected by the grab, which is 15 centimeters deep in the deepest part of the sampler. See the cross-references for a description of the SEABOSS system.

Process_Description:
Using 2016-038-FA_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 (awksampleimages_2016-038-FA) 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 - 2016-038-FA_grabimage_locations.csv. This CSV file was then manually edited to remove records that referenced stations with no sediment sample. This process step and the subsequent process steps (unless otherwise noted), were performed by the same person - VeeAnn A. Cross.

Process_Description:
A Python script (writeexif_2_readfile_7_25_19.py executed with IDLE version 2.7.14) was then run that incorporated the information from 2016-038-FA_grabimage_locations.csv, along with additional information, into the appropriate tags in the EXIF header of each grab image at each station. The Python script uses ExifTool (version 11.54) 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 because different software packages access different tags.
GPS tags: The values populated are unique for each image and based on the information exported from 2016-038-FA_station_data_summary.csv.

To extract the information from the image headers using ExifTool, the following command can be used (tested with ExifTool version 11.54):
exiftool.exe -csv -f -filename -GPSTimeStamp -GPSDateStamp -GPSLongitude -GPSLatitude -n -Artist -Credit -comment -keywords -Caption -Copyright -CopyrightNotice -Caption-Abstract -ImageDescription -UserComment *.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. Whether you use exiftool or exiftool.exe will depend on the system on which the command is being run.
