Description:
Abstract:
This field activity is part of an 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-scale) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. The data collected in this study will aid research on the ecology of fish and invertebrate species that inhabit the region. On August 22 and 23, 2017, the U.S. Geological Survey, in collaboration with the Stellwagen Bank National Marine Sanctuary, conducted a research cruise aboard the Sanctuary’s Research Vessel Auk, visiting 39 locations within the sanctuary. A customized Van Veen grab sampler (SEABOSS) equipped with a video camera and a conductivity, temperature, and depth (CTD) instrument 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 of the SEABed OBservation and Sampling System (SEABOSS) 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. 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 2017-043-FA_station_data_summary file available from the Larger Work citation.

Logical_Consistency_Report:
The image names are in the format: 2017043FAXXXX_staYYYY_Z.JPG. The designation 2017043FA is the field activity number assigned to the cruise by the Woods Hole Coastal and Marine Science Center; the first four digits represents the year, and the next three digits represent the activity number in that year; XXXX is the image number recorded by the camera; YYYY is the station number; Z represents R or L, the right and left-hand sides of the sample surface in the grab sampler. Of the 37 samples collected, 27 of the sediment sample have 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. Stations 4635-4644 only have the right-hand surface photographed. When the sampler was completely full, both sides looked the same so only one photo was necessary. In these instances, the sampler was full. 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 37 of the 39 stations visited. Most sediment samples have 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. For 10 stations (4635-4644) only the right-hand side was photographed (10 images); for the other 27 samples, both right-hand and left-hand sides were photographed (54 images); giving a total of 64 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:
Still images of sediment sample surfaces were collected using a hand-held Nikon 7100 digital camera with a resolution of 24 megapixels (6000 x 4000 pixels), using a 18-200x zoom lens with an aperture ranging from f3.5 to f5.6. A Nikon macro Speedlight was used for illumination. After retrieval of the SEABOSS and placement on its wooden stand, the two doors (right and left) in 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 except when the sampler was complete full. In those instances, both sides looked the same so only one photo was necessary. 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 cm deep in the deepest part of the sampler.

Process_Step:
Process_Description:
Using the 2017-043-FA_station_data_summary.csv, the approximate time and location of each photo was derived. Two stations in the summary file were for plankton tows, so those records were deleted for this process. Any station that did not collect a sediment sample was also deleted. The station location (latitude and longitude), date and time for each remaining station was extracted from the CSV file. This information was reformatted using an awk script (awksampleimages_2017-043-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 - 2017-043-FA_grabimage_locations.csv. This CSV files was then manually edited to remove records that referenced "L" images that did not exist. Also, the image name was manually edited to add the original image number recorded by the camera, and change "jpg" to "JPG". 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 2017-043-FA_grabimage_locations.csv, along with additional information, into the appropriate locations in the EXIF header of each grab image at each station. 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.
