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 50 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.

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. Completeness_Report: Sediment samples were collected at 41 of the 50 stations visited. All 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, giving a total of 82 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 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). Lineage: Process_Step: 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. 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. 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. See the cross-references for a description of the SEABOSS system.

Six 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 station was extracted from the CSV file. This information was reformatted using an awk script (awksampleimages_2017-030-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 - 2017-030-FA_grabimage_locations.csv. This process step and subsequent process steps (unless otherwise noted), were performed by the same person - VeeAnn A. Cross.

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. This was done because different software packages access different tags.
