Title:
Location of bottom photographs along with images collected by the U.S. Geological Survey in 2015 along the Delmarva Peninsula, MD and VA (JPEG images and Esri point shapefile, Geographic, WGS 84)
Abstract:
The Delmarva Peninsula is a 220-kilometer-long headland, spit, and barrier island complex that was significantly affected by Hurricane Sandy in the fall of 2012. The U.S. Geological Survey conducted cruises during the summers of 2014 and 2015 to map the inner continental shelf of the Delmarva Peninsula using geophysical and sampling techniques to define the geologic framework that governs coastal system evolution at storm-event and longer timescales. Geophysical data collected during the cruises include swath bathymetric, sidescan sonar, chirp and boomer seismic reflection profiles, grab sample and bottom photograph data. More information about the USGS survey conducted as part of the Hurricane Sandy Response-- Geologic Framework and Coastal Vulnerability Study can be found at the project website or on the WHCMSC Field Activity Web pages: https://woodshole.er.usgs.gov/project-pages/delmarva/, https://cmgds.marine.usgs.gov/fan_info.php?fan=2014-002-FA and https://cmgds.marine.usgs.gov/fan_info.php?fan=2015-001-FA.

Why was the data set created?

This dataset is used to display the images and locations of bottom photographs acquired with a GoPro modified, mid-sized SEABed OBservation and Sampling System (SEABOSS Mark II configuration) collected during a 2015 USGS cruise along the Delmarva Peninsula. The information contained within the bottom photographs is needed to validate geophysical data. This dataset contains seabed images from each bottom photograph station, as well as location in Geographic coordinates (WGS84), time of day and date of collection. Physical sediment samples, which provide additional information about the seabed, were also collected at photograph stations and analyzed in the sediment laboratory at the USGS Woods Hole Coastal and Marine Science Center (see shapefile 2015-001-FA_samples.shp available from the larger work citation).

How was the data set created?

  1. From what previous works were the data drawn?
    raw hypack nav and bottom photographs (source 1 of 1)
    U.S. Geological Survey, 2016, Bottom photographs and locations.

    Type_of_Source_Media: disc
    Source_Contribution:
    Bottom photographs and sediment samples were acquired to validate the seafloor interpretations made from geophysical data. Often sediment samplers are unable to recover large-diameter particles, so photographs can document the seafloor character in areas where samples may not be obtained. Two GoPro cameras were mounted to a USGS SEABOSS (Mark II configuration) with a modified VanVeen sampler frame. Approximate SEABOSS dimensions are 115 X 115 X 117 cm. The Van Veen sampler is housed at the bottom and center of the frame at approximately 30 X 32 X 16 cm with a 1/10 sq. meter sample capacity. Two red lasers were mounted on the frame above the sampler, 20 cm apart for scale in bottom photographs. A Keldan (Advanced Lighting Technology) light was mounted at the top of the frame and aimed downward to illuminate the seabed for photographs. Two GoPro cameras were mounted on the frame and set to capture photographs at 2 or 5 second intervals. The GoPro Hero 2 was mounted approximately 70 cm from the bottom of the SEABOSS frame and captured photographs at 2-second interval. The GoPro Hero 3+ was mounted approximately 20 cm from the bottom of the SEABOSS frame and captured video and photographs at 5-second interval. Because the frame was stationary on the bottom of the seabed only one photograph for each camera was chosen to represent the seafloor at each station location. Photographs collected in the water column, on the ship's deck, and duplicate photos of the seafloor were deleted. The Hero 2 field of view includes the Hero 3 GoPro (furthest to the right) and 2 instruments that were attached to the SEABOSS for additional data. The instrument to the left is a Suunto SK-7 dive compass, which shows the orientation of the SEABOSS. The digital readout to the right of the dive compass is the Uwatec dive timer, which shows 4 readouts: upper left is depth in meters, lower left is max depth in meters, upper right is dive time in minutes and lower right is temperature in Celsius (during ascent, this changes to ascent rate in meters per minute and shows an arrow when it senses the rate is too fast).

    Date: 20-Oct-2015 (process 1 of 10)
    DGPS and WAAS navigation for the Hemisphere receiver (located on the acquisition van) were logged in HYPACK software (versions 13.0.9.21 and 15.0.9.71). A python script called parseHYPACK_gui_sort_all.py (WHCMSC script) was used to search all HYPACK files from the sampling Julian days (JD 195-197) and pull out the GPGGA (nav) string (Device 0) and time and write out a parsed navigation file for all the sample and photograph stations.

    Time of bottom photograph was extracted from the "Date Picture Taken" attribute in the EXchangeable Image File format (EXIF) header of the quality JPEG bottom photograph using a python tool called: JPEG_exifextract_gui_sort.py (WHCMSC script). A separate picture time file was created for each camera, Hero 2 and Hero 3. Person who carried out this activity:

    Adjustments were made manually to the time picture taken file to account for time offsets between the time recorded in the JPEG EXIF "Date Picture Taken" attribute and the GPS time as verified by comparing calibration photos taken on the deck of the ship. Hero 2 was 31 minutes and 10 seconds behind GPS time, and the Hero 3+ was 1 second ahead of GPS time. To account for the time difference, an additional field was added to the photo 'time picture taken' file generated in the previous step. The new field of the time difference was populated using Microsoft Excel (version 2010) by auto-filling a linear series. The time difference is used for geolocating the photos in the subsequent processing step. Person who carried out this activity:

    An Esri shapefile was created by using a python script (photo_locs_gui_5exif.py, WHCMSC script) to join the bottom photo with the parsed HYPACK navigation file by matching the time offset field for Hero 2 photos (31 minutes, 10 seconds) and Hero 3+ photos (1 second) with the navigation file.

    Once the shapefile was created that joined the latitude and longitude from the HYPACK navigation with a photo from each station, some fields were deleted that were no longer needed including the camera time and time offset fields for Hero 2 and Hero 3. Several attributes were added in Esri ArcGIS (version 10.3.1) using the Spatial Join Tool. This tool was run with the sediment sample shapefile (containing sample analysis information) to assign a station name for the accompanying sediment sample (FIELD_NO) and also the sediment classification (Folk scheme) of the accompanying sediment sample (CLASSIFICA). Bottom photo and sediment sample locations are not exactly coincident as the ship drifted during the collection of bottom photos. Person who carried out this activity:

    The photo locations were exported from ArcMap (version 10.3.1) using XTools Pro (version 12.0) as a comma-delimited text file. The attributes chosen for export were: GPSTIME, PICNAME, LONG, LAT. Another column of information was added - yrdate - which had the year and date the photograph was taken in the format YYYYMMDD. This information was based on the Julian day in the shapefile. A Python version 2.7.3 script (writeexif_2_readfile_11_24_15.py, WHCMSC script) was then run that incorporated this information, along with additional information, into the appropriate locations in the EXIF header of each full-resolution JPEG image. 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.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    The GoPro Hero 2 HD camera used on the SEABOSS Mark II acquires photos at 11 Megapixels in JPEG quality of 98 percent, so file sizes are generally between 3 and 7 MB on disc, depending on seabed complexity. The GoPro Hero 3+ black camera used on the SEABOSS Mark II acquires photos at 12 Megapixels in JPEG quality of 80%, so file sizes are generally between 1 and 3 MB on disc. Image quality and photo interval was reduced for Hero 3+ to allow space on camera card for bottom video.
  2. How accurate are the geographic locations?
    Differential Global Positioning System (DGPS) and Wide Area Augmentation System (WAAS) enable GPS navigation data were acquired with a Hemisphere receiver and recorded with HYPACK software versions 13.0.9.21 and 15.0.9.71 (www.hypack.com). The recorded position of each bottom photograph is the position of the GPS antenna on the survey vessel acquisition van, not the SEABOSS sampler. The SEABOSS was deployed approximately 5 meters astern of the GPS antenna off the ship's A-fame on the stern of the ship. No layback or offset was applied to the recorded position. In addition to the plus or minus 5 m offset the SEABOSS may additionally drift away from the survey vessel when deployed to the seafloor. Based on the various sources of horizontal error, a conservative estimate of the horizontal accuracy of the bottom photograph location is 20-30 m.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    The best photograph from each camera is included at each station. Not every station has a photograph from both cameras. There is no bottom photograph collected for sample S_006. There are 235 bottom photos total: 121 photos from the Hero 2 and 114 photos from the Hero 3.
  5. How consistent are the relationships among the observations, including topology?
    All bottom photographs were acquired with the same 2 cameras; a GoPro Hero 2 HD (Hero 2) and a GoPro Hero 3+ black (Hero 3). Cameras were mounted on a mid-sized SEABOSS with a modified VanVeen Sampler. Gaps in sequential photo numbers exist because only the best photo per station was selected for publication (See source contribution for more information on camera settings and photograph timing). Some stations did not obtain a quality photo due to frame movement, or an unsettled (muddy) seabed. Of 125 sample stations, there are Hero 2 photos for 121 stations, and Hero 3 photos at 114 stations.
