Brothers 2015 3.0 data release DOI:10.5066/F7MW2F60 Reston, VA U.S. Geological Survey https://doi.org/10.5066/F7MW2F60 The Delmarva Peninsula is a 220-kilometer-long headland, spit, and barrier island complex that was significantly affected by Hurricane Sandy. A U.S. Geological Survey cruise was conducted in the summer of 2014 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. Data collected during the 2014 cruise include swath bathymetry, sidescan sonar, chirp and boomer seismic-reflection profiles, acoustic Doppler current profiler, and sample and bottom photograph data. Processed data in raster and vector format are released here for the bottom photographs and sediment samples. 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/ and https://cmgds.marine.usgs.gov/fan_info.php?fan=2014-002-FA 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 2014 USGS cruise along the Delmarva Peninsula. The information contained within the bottom photographs is needed to validate geophysical data. This dataset contains an image from each bottom photograph station, as well as location in easting and northing (UTM, Zone 18N, WGS84, meters), time of day and date of collection. Physical sediment samples, which also may provide 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 2014_002_samples.shp) 20140722 20140725 ground condition; sample and photo data were collected after geophysical data collection was complete.

Blackwood K. Parolski 2001 1.0 Sea Technology v. 42, no. 2, p. 29-43 Arlington, VA Compass Publications, Inc. 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. All bottom photographs were acquired with the same 2 cameras; a GoPro Hero 2 HD (Hero2) and a GoPro Hero 3+ black (Hero3). 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 133 sample stations, Hero 2 recovered quality photos for 106 stations, and Hero 3 recovered quality photos at 99 stations. The best photograph from each station is included in a camera folder. If a quality photo was not obtained from either camera at a station, then the location is not included in the Esri shapefile and no image is available in the camera folder for Hero 2 or Hero 3. Differential Global Positioning System (DGPS) navigation data were acquired with a Hemisphere receiver and recorded with HYPACK (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. U.S. Geological Survey 2015 disc 20140722 20140725 ground condition; sample and photo data were collected after geophysical data collection was complete. raw hypack nav and bottom photographs 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. 1 Keldan (Advanced Lighting Technology) light was mounted at the top of the frame and aimed downward to illuminate the seabed for photographs. 2 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 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. DGPS navigation for the Hemisphere receiver located on the acquisition van were logged in HYPACK software (version 14.0.9.47). A python script called parseHYPACK_gui_sort_all.py was used to search all HYPACK files from the sampling Julian days and pull out the GPGGA (nav) string and time and write out a parsed navigation file for all the sample and photograph 2015 Seth Ackerman U.S. Geological Survey Geologist mailing and physical address

Woods Hole MA 02543-1598 (508) 548-8700x2315 (508) 457-2310 sackerman@usgs.gov 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 12 seconds behind GPS time and Hero 3 was 19 seconds behind 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. 2015 Seth Ackerman U.S. Geological Survey Geologist mailing and physical address

The attributes chosen for export were: TIME, 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 dat in the shapefile. A Python version 2.7.3 script (writeexif_2_readfile_11_24_15.py) 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. These images will eventually be incorporated into the WHCMSC photo database and the EXIF header information is a requirement for the database. > The following tags were populated in the JPEG image headers.
