Description:
Abstract:
Accurate data and maps of sea-floor geology are important first steps toward protecting habitat, delineating marine resources, and assessing environmental changes due to natural or human effects. Initiated in 2003, the primary objective of the Geologic Mapping of the Massachusetts Sea Floor program is to develop regional geologic framework information for the management of coastal and marine resources. The project is focused on the inshore waters (5–30 meters deep) of Massachusetts. This dataset is from U.S. Geological Survey (USGS) sampling survey 2011-015-FA (September 9–16, 2011) by the USGS Woods Hole Coastal and Marine Science Center and the Massachusetts Office of Coastal Zone Management with partners from the Massachusetts Division of Marine Fisheries and the U.S. Environmental Protection Agency aboard the ocean survey vessel Bold. During the survey, surficial sediment samples and bottom still and video imagery were collected in Cape Cod Bay, Buzzards Bay, and Vineyard Sound; south of Martha's Vineyard; and south and east of Nantucket, Massachusetts.
Purpose:
This dataset is used to display the images and locations of bottom images acquired with a Konica Minolta DiMAGE A2 digital camera or Kongsberg Simrad OE1365 video camera on the SEABed Observation and Sampling System (SEABOSS) or a GoPro HD HERO camera on a Van Veen grab collected during USGS survey 2011-015-FA. Imagery data serve as a means to visually classify grain size and are especially important for sites where no physical sediment sample was collected.
Supplemental_Information:
Bottom video, which may provide a better representation of the general seabed environment over a larger area, was also taken at all stations occupied by the SEABOSS (see shapefile 2011-015-FA_videos.shp available from the larger work citation; see the Coastal and Marine Geology Program Video and Photograph Portal to view the bottom videos [Golden and others, 2015; link available from the cross-reference citation]). Physical sediment samples were also collected at many stations and analyzed for grain size (see shapefile 2011-015-FA_samples.shp available from the larger work citation) and benthic infauna (see report by the Massachusetts Office of Coastal Zone Management [2012] available from the cross-reference citation).

Attribute_Accuracy:
Attribute_Accuracy_Report:
Camera time drift and the precision with which the camera time can be set often result in an offset. The Konica Minolta DiMAGE A2 camera time was set to Coordinated Universal Time (UTC); calibration photographs with the navigation system indicate that the time offset drifted by up to 67 seconds throughout the survey, so this time offset was corrected for in the imagery processing by interpolating an offset between each calibration photo. Spot checking the interpolated photo times with the bottom video showed that the interpolated times may be off by up to two seconds. The GoPro HD HERO camera time was set to local time (UTC-04:00) and was not assessed for accuracy or used for geolocating the photos; rather, the time of the station's sediment sample grab was used for the GoPro photos' Global Positioning System (GPS) time and to geolocate the photos. For the attributes related to the nearest sediment sample (NEAR_SMP, NEAR_CLASS, DST_TO_SMP, and NR_SMP_CMT), please note that the term "sediment samples" may be used to describe physical samples as well as stations where the bottom type was determined by visual observation of the last still image of the sea floor taken during the sampler deployment, which is noted in the comments field (NR_SMP_CMT). The visual observation sediment sample locations are not necessarily coincident with the location of the bottom image used to determine the sediment classification and are generally located at the start of the sampler retrieval. Therefore, the distance in meters from a bottom image to the nearest sediment sample (DST_TO_SMP) does not necessarily represent the distance to the image used to determine the sediment classification for the visual observation sediment samples.
Logical_Consistency_Report:
Bottom imagery was acquired with three different cameras: a Konica Minolta DiMAGE A2 digital still camera, Kongsberg Simrad OE1365 video camera, and GoPro HD HERO digital camera. For the Konica Minolta DiMAGE A2 photos, gaps in sequential photo numbers exist. Generally, Konica Minolta photos without a clear view of the sea floor were deleted. If the Konica Minolta camera was triggered accidentally on deck or a picture did not come out, it was deleted. For the Kongsberg Simrad OE1365 still-image frame grabs, some images have a time stamp on them because some videos were recorded with an overlay of the GPS time. For the GoPro photos, only the single best photo per station was selected for publication. For some stations, only a blurry or dark GoPro image was available, so it was kept and included in this dataset. The station numbers (FIELD_NO) were determined before the survey and are not necessarily in sequential order of when they were occupied. Gaps in sequential station numbers exist as not all planned stations were occupied during the survey. Two sites were occupied twice on different days during the survey, so the station number for the data collected when they were occupied the second time ends in "0.2" (i.e., stations 81.2 and 95.2); these sites are considered unique stations (e.g., 81 and 81.2 are two different stations).
Completeness_Report:
This dataset includes bottom imagery in JPEG format and a shapefile of the locations of images collected during USGS survey 2011-015-FA. Three hundred twenty-two stations were occupied within the study area, but the SEABOSS was only operational for 246 sites. Sixty-five of those 246 sites did not have any usable photographs, so still-image frame grabs were captured from the video to supplement this dataset. For those sites with usable photos from the SEABOSS, the photos were acquired with a Konica Minolta DiMAGE A2 camera. Photos taken in the water column, on deck, or without a clear view of the sea floor were deleted. The remaining stations were occupied using the ship's Van Veen grab sampler equipped with a GoPro HD HERO camera. Only the single best GoPro photo per station was selected for publication. Imagery from all but one station (station 418, which did not have any GoPro photos) is included in this dataset. A total of 1,071 images are included in this dataset.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Sources of horizontal inaccuracy may be due to the camera time or navigation data. The original JPEG images alone do not represent spatial data; however, the images were geolocated during post-processing by linking the time the image was taken to the corresponding time in the navigation data. The Konica Minolta DiMAGE A2 camera time drifted by up to 67 seconds throughout the survey, so this time offset was corrected for in the imagery processing by interpolating an offset between calibration photos. Spot checking the interpolated photo times with the bottom video showed that the interpolated times may be off by up to two seconds. Navigation for survey 2011-015-FA used Differential Global Positioning System (DGPS). The DGPS was set to receive fixes at a two-second interval in geographic coordinates (World Geodetic System of 1984 [WGS 84]), so photos taken at a time with odd seconds were geolocated using the closest available fix. The recorded position of each image is the position of the DGPS antenna on the survey vessel, not the SEABOSS or Van Veen grab sampler. The antenna was at the top of the vessel's A-frame from which the sampler was deployed, within a few meters of the sampler. No layback or offset was applied to the recorded position. In addition to the +/- 3-meter offset, the sampler may drift away from the survey vessel when deployed to the sea floor. Based on the various sources of horizontal offsets, a conservative estimate of the horizontal accuracy of the bottom imagery locations is 5-20 meters, but offsets are most likely within 3-10 meters.

Source_Contribution:
Bottom imagery was acquired using the large SEABOSS, where operational, or the ship's Van Veen grab sampler equipped with a GoPro HD HERO camera. The observations from video and still cameras and the sediment data are used to explore the nature of the sea floor and, in conjunction with high-resolution geophysical data, to make interpretive maps of sedimentary environments and validate acoustic remote sensing data. The SEABOSS incorporates two video cameras (one forward-looking so that a shipboard operator can monitor for proper tow depth and obstacles, and one downward-looking, a Kongsberg Simrad OE1365 video camera in this setup, that overlaps with the field of view of the still camera), a still camera (Konica Minolta DiMAGE A2 in this setup), and a modified Van Veen sediment sampler. The elements of this particular SEABOSS system are held within a stainless-steel frame that measures 1.1 x 1.1 meters. The frame has a stabilizer fin that orients the system as it drifts over the seabed. The OSV Bold occupied one of the target stations and the SEABOSS was deployed off the vessel's A-frame on the stern of the ship. The vessel and sampler drifted with wind and current for up to a few minutes to ensure a decent image with a clear view of the sea floor and then at most stations the sea floor was sampled with the SEABOSS's integrated Van Veen grab. Sediment samples were only attempted in areas where collecting a sample would not damage the SEABOSS; therefore, no samples were collected in areas with a cobble, boulder, or rocky seabed, as identified in real time using the top-side live video feed. At some sites, samples were attempted one or more times in what appeared in the real-time video as sand or mud, but no sample was successfully collected. The system was then raised and recovered to the deck of the survey vessel. The Konica Minolta digital photos were saved to the camera's SD memory card and periodically downloaded from the camera during the survey. The camera time was set to UTC; calibration photographs with the navigation system indicate that the time offset drifted by up to 67 seconds throughout the survey and this time offset was corrected for in the imagery processing. Photos taken in the water column, on deck, or without a clear view of the sea floor were deleted. The still camera was occasionally malfunctioning, so some stations did not have any usable photographs. For these stations, still-image frame grabs were captured from the bottom video to supplement this dataset. Bottom video was recorded from the Kongsberg Simrad OE1365 downward-looking video camera on Digital8 tapes and backup DVDs. The SEABOSS was only operational for 246 of the 322 stations occupied during this survey. Since the SEABOSS's still camera was occasionally malfunctioning, use of the SEABOSS was halted partway through the survey and the remaining stations were occupied using the ship's Van Veen grab sampler equipped with a GoPro HD HERO camera and dive lights. The ship's sampler was deployed off the vessel's A-frame on the stern of the ship and lowered until the sea floor was sampled. There was no top-side live video feed, so the vessel and sampler did not drift over the seabed, video was not collected, and samples were attempted at all stations occupied using the ship's Van Veen grab sampler. The GoPro digital photos were saved to the camera's SD memory card and periodically downloaded from the camera during the survey. The GoPro was set to capture photographs at a one- or two-second interval. Because the frame was stationary on the seabed, only one GoPro photograph was chosen to represent the sea floor at each station location. The GoPro camera time was set to local time (UTC-04:00) and was not assessed for accuracy or used for geolocating the photos; rather, the time of the station's sediment sample grab was used for the GoPro photos' GPS time and to geolocate the photos. DGPS navigation from a Garmin GPSMAP 76CSx receiver was logged through a Microsoft HyperTerminal (version 5.1) session on a Dell Latitude D820 laptop computer running Windows XP SP2 via serial cable. The DGPS was set to receive fixes at a two-second interval in geographic coordinates (WGS 84). Log files were saved for each sampling watch in ASCII text format.

Process_Description:
Three hundred twenty-two stations were occupied aboard the OSV Bold during USGS survey 2011-015-FA with the large SEABOSS (Blackwood and Parolski, 2001), where operational, or the ship's Van Veen grab sampler. The SEABOSS was equipped with a Van Veen grab sampler, a Konica Minolta DiMAGE A2 digital still camera, and two video cameras (forward- and downward-looking). The still camera was occasionally malfunctioning, so the SEABOSS was only operational for 246 of the 322 stations. The remaining stations were occupied using the ship's Van Veen grab sampler equipped with a GoPro HD HERO camera (set to capture photographs at a two-second interval for the first 10 stations, then a one-second interval for the remaining sites) and dive lights. Bottom imagery was acquired at all but one station (station 418). The Konica Minolta and GoPro digital photos were downloaded from the cameras and backed up to a laptop and hard drive periodically during the sampling survey. Sixty-five stations occupied using the SEABOSS did not have any usable photographs, so still-image frame grabs were captured from the bottom video for these stations in a subsequent process step. Bottom video was recorded from the Kongsberg Simrad OE1365 downward-looking video camera on Digital8 tapes and backup DVDs.

The DGPS was set to receive fixes at a two-second interval in geographic coordinates (WGS 84). Log files were saved for each sampling watch in ASCII text format. The original log files were reformatted into log files by full Julian day. An AWK script (awkseth.gpgga.sda) was run on the log files to parse for the GPGGA navigation string and create ASCII Comma Separated Value (CSV) text files. The output files were merged and then reformatted using an AWK script (nav_time_reformat.awk), creating a final processed navigation file for the entire sampling survey.

Process_Description:
Bottom photographs acquired with the Konica Minolta DiMAGE A2 were culled to remove photos taken in the water column, on deck, or without a clear view of the sea floor. Sixty-five stations with no usable photographs from the Konica Minolta were identified. For these stations, one to 10 still-image frame grabs per station were captured from the SEABOSS bottom video taken with a downward-looking Kongsberg Simrad OE1365 video camera. This was a manual process whereby the video was viewed in VLC media player and clear images of the sea floor approximately equally distributed throughout the drift were captured. Fewer frame grabs were captured for shorter drifts or for video without a clear view of the sea floor. Some videos were recorded with an overlay of the GPS time, so some frame grabs have a time stamp on them. Bottom photographs acquired with the GoPro HD HERO were culled to choose the single best photograph at each station since the frame was stationary on the sea floor.

Process_Description:
The original JPEG images alone do not represent spatial data, however, they can be geolocated by linking the time the image was taken, which was recorded in the JPEG files' Exchangeable image file format (Exif) headers, to the corresponding time in the navigation logs. Camera time drift and the precision with which the camera time can be set often result in a time offset. The Konica Minolta DiMAGE A2 camera time was set to UTC; calibration photographs with the navigation system indicate that the time offset drifted by up to 67 seconds throughout the survey, so this time offset was corrected for in the imagery processing by interpolating an offset between each calibration photo. A shapefile was created by using the Esri ArcGIS 9.3 ArcToolbox tool "GeoTools Hotlink Tool - SDA Feb05" (which uses the Python [version 2.5] script "photo_locations_offsetmod.py" [version Feb. 22, 2012]) to join the Konica Minolta photos with the parsed navigation file by matching the time offset field for the photos with the navigation file. A CSV file of the shapefile was exported from Esri ArcGIS using XTools Pro (version 7.1).

Process_Description:
The GoPro HD HERO camera time was set to local time (UTC-04:00) and was not used for geolocating the photos; rather, the time of the station's sediment sample grab was used to geolocate the photos. Using Microsoft Excel 2016 for Mac, the GPS time and coordinates for the GoPro photos were populated in a CSV file by matching the photo's station number with a CSV file of the sediment sample locations. The three CSV files for the Konica Minolta, video frame grab, and GoPro imagery were merged into one file with fields for the filename, latitude, longitude, GPS date, and GPS time.

Process_Description:
A shapefile was created using the bottom imagery locations CSV file in Esri ArcGIS (version 10.3.1). Several attributes were then added using the Spatial Join tool. This tool was run with the bottom video tracklines shapefile to calculate the video trackline for each bottom image (LINENAME). The intersect match option with a search radius of 10 meters was used because some images were taken shortly before or after the video trackline. Eighty-three images were not within 10 meters of a trackline, so a no data value of -9999 was assigned to these images using the field calculator. These images were taken during the second deployment of the SEABOSS at a station where no video was collected (stations 18, 42, 48, 65, 290, and 292), or when the SEABOSS was not operational and there was no video camera (stations where DEVICE_ID = EPA VAN VEEN). The shapefile was then projected to WGS 84 UTM Zone 19N so that the distance in meters to the closest sediment sample could be calculated when running the Spatial Join tool. Note that the term "sediment samples" used herein may be used to describe physical sediment samples as well as stations where no physical sediment sample was collected, but the bottom type was classified by USGS geologists based on the visual observation of the last still image of the sea floor taken during the sampler deployment. The sediment samples shapefile includes all 322 stations that were occupied during the survey; however, three sites (stations 167, 420, and 421) did not have a physical sediment sample or any imagery with a clear view of the sea floor and were therefore not classified. The Spatial Join tool was then run with the sediment samples shapefile, which had a definition query to filter out stations with no sediment classification ("CLASSIFICA" < 'NO SAMPLE'), to assign the station number of the closest sediment sample (NEAR_SMP), the sediment classification of the nearest sample (NEAR_CLASS), the distance in meters between the bottom image and nearest sediment sample (DST_TO_SMP), and the comment field for the nearest sample (NR_SMP_CMT). Next, the distance in meters between the bottom image and closest sample (DST_TO_SMP) was rounded to the nearest tenth using the field calculator. The Spatial Join tool was run again with the sediment samples shapefile with the definition query removed to assign the station number for each bottom image (FIELD_NO). The shapefile was then projected back to WGS 84 and unnecessary fields created when running the Spatial Join tool were deleted (e.g., Join_Count, TARGET_FID, etc.).

XTools Pro (version 12.0) for Esri ArcGIS (version 10.3.1) was used to reorganize and add new fields (Table Operations - Table Restructure) to the point shapefile, including an attribute for the survey ID (CRUISE_ID), sampling device used to collect the imagery (DEVICE_ID), and survey vessel (VEHICLE_ID). The shapefile's attribute table was exported in Esri ArcGIS (version 10.3.1) and saved as a CSV file. The FID field was deleted in the CSV file.

Process_Description:
A Python script (MCZM_writeexif_2_readfile.py) was run that incorporated the matched-up location data, along with additional survey information, into the appropriate tags in the Exif header of each JPEG image. Since the imagery was acquired with three different cameras, the script was run separately for each camera's imagery using slightly different tags. The Python script uses ExifTool (version 10.17) to write the information to the image headers. Information is duplicated in some tags because various software packages access different tags. The following tags were populated in the JPEG image headers:

GPS tags (these values are unique for each image and based on the matched-up location data):
GPSLatitudeRef
GPSLatitude
GPSLongitudeRef
GPSLongitude
GPSTimeStamp
GSPDateStamp

JPEG tag and the information used to populate this tag, which is different for each camera's imagery:

Attribute_Definition:
Station number for the trackline along which continuous bottom video, where the SEABOSS was operational, was acquired. Two sites were occupied twice on different days during the survey, so the station number for the data collected when they were occupied the second time ends in "0.2" (i.e., stations 81.2 and 95.2). Two stations (stations 83 and 123) have two SEABOSS bottom video tracklines, so the tracklines were named "a" and "b" to indicate back-to-back deployments at the same station (e.g., line names 83a and 83b). A no data value of -9999 indicates that the image is not within 10 meters of a bottom video trackline. Not all images were taken along a trackline because video was not always taken during the second deployment of the SEABOSS at a station and the ship's Van Veen grab sampler did not have a video camera.
