Description:
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. Data collected during the 2014 survey can be obtained here: https://doi.org/10.5066/F7MW2F60
Purpose:
PNG images of each seismic profile were generated in order to incorporate images of the seismic profiles into Geographic Information System (GIS) projects. These data represent approximately 5,500 km of chirp seismic-reflection data collected by the U.S. Geological Survey during cruise 2015-001-FA along the Delmarva Peninsula, MD and VA. Each profile image can be hotlinked to its corresponding trackline navigation contained within the Esri polyline shapefile '2015-001-FA_512i_tracks.shp'. Shotpoint index markers along the top of the PNG images correlate to the positions of 500 shot intervals within the Esri point shapefile '2015-001-FA_512i_500sht.shp'.

Logical_Consistency_Report:
Processed seismic data were converted to PNG format for ease of seismic trace display. Quality control was conducted during processing.
Completeness_Report:
Sections of tracklines where navigation was recorded but no seismic data were logged are not included such as some turns and transits. There is a single image for every trackline. There is no line l155f1.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Although navigation is not stored in the images, positional accuracy is relevant to the accuracy of these data. The EdgeTech SB-0512i subbottom profiler was mounted on a catamaran sled and towed at the sea surface approximately 43 m astern of the M/V Scarlett Isabella. The transducer depth below water line was 0.5 meters below catamaran floats. Navigation data for the 512i were collected using a Differential GPS (DGPS) and Wide Area Augmentation System (WAAS) GPS enabled Garmin receiver, which was located on the catamaran sled and connected to the acquisition computer via a serial cable. Positioning data were recorded in SonarWiz (versions 5.00.015 and 5.06.0058) acquisition software, which logged positioning coordinates to individual trace headers SEG-Y and JSF format. Horizontal positional accuracy is assumed to be within 2 m at the GPS receiver; however, horizontal position uncertainty increases with sonar and sled motion, which was not compensated for at the sonar transducer.

Source_Contribution:
Chirp seismic data were collected using an EdgeTech Geo-Star FSSB sub-bottom profiling system and an SB-0512i towfish (0.5-12 kHz), which was mounted on a catamaran and towed astern of the M/V Scarlett Isabella of Cape May, NJ. Chesapeake Technology's SonarWiz (versions 5.00.0015 and 5.06.0058) seismic acquisition software was used to control the Geo-Star topside unit, digitally log trace data in the SEG-Y Rev. 1 format (IEEE floating point) and JSF format, and record GPS navigation coordinates to the SEG-Y trace headers (in arc seconds of Latitude and Longitude, multiplied by a scalar of 100). Data were acquired using a 250 ms shot rate, a 5-ms pulse length, and a 0.5 to 8 kHz frequency sweep. Recorded trace lengths were approximately 180 ms.
Process_Step:
Process_Description:
Scripts within SIOSEIS (version 2013.1.1) and Seismic Unix (version 4.2) were used to process SEG-Y data, create navigation files, and plot images. The processing flow and scripts used to produce swell-filtered PNG images are summarized below:
1. SIOSEIS (version 2013.1.1) was used to read SEG-Y files, renumber shots starting from one, extract the envelope-detected trace, and write out new SEG-Y files. The original shot numbers, which were assigned by SonarWiz sequentially over the duration of an acquisition session despite SEG-Y file changes, are preserved in the raw SEG-Y data.
2. The SIOSEIS script Sio_medianstk was used to minimize S-boom cross talk (when multi-channel streamer lines were recorded simultaneously: Julian day 161-168) with a two-trace median stack (trim 50 percent of the values furthest from the median amplitude) and improve water bottom picking. This script was used for all lines even after multi-channel streamer was turned off, due to the improvements made to water bottom picks.
3. The script Read512i_mstk was used to read median filtered stacked and renumbered SEG-Y files, write a Seismic Unix file, and extract SEG-Y trace header information, including shot number, longitude, latitude, year, Julian day, and time of day (UTC). Header information from each SEG-Y file was saved to text files after an AWK (no version) filter was used to maintain the first and last shots, shots at multiples of 100, 500, and shots with unique navigation coordinates. Geographic coordinates (WGS 84) were converted to UTM zone 18 N coordinates (WGS 84) using Proj (version 4.6.0). End shots and shots at multiples of 100 may not have unique navigation coordinates. Separate text files containing the first and last shots and even 500 shot intervals were also saved. A 500 shot interval was chosen because it corresponds to the annotation interval provided along the top of the seismic-reflection profile images. Read512i_mstk called a Python script 512itoSQL15001.py, written by Wayne Baldwin, which imported the CSV files to the Spatialite (version 3.0.1) enabled SQLite (version 3.7.9) database.
4. The SIOSEIS script siothresh_pltwbt was used to pick the water-bottom time from the median stacked SEG-Y files, apply a swell filter to smooth water-bottom time picks and shift the trace data by the difference between the smoothed and unsmoothed water bottom time before writing the shifted trace data to a new SEG-Y file.
5. The Seismic Unix script Plot512i_s creates a swell-filtered PNG image using ImageMagick (version 6.6.1) of each seismic line that is 12 inches high. Images show two-way travel time (seconds) along the y-axis (left margin) and distance along profile (in 10,000 shot intervals) on the x-axis (along top of profile).

The online links to the data were updated to reflect the new server hosting the data. The original release had 3 download files (2015-001-FA_512i_images1of3.zip, 2015-001-FA_512i_images2of3.zip, 2015-001-FA_512i_images3of3.zip) with each file approximate 3.5 GB in size. In order to facilitate downloads, the data were broken into smaller zip files. A total of 11 zip files were created with each file approximately 1 GB insize. Each file contains a portion of the seismic-reflectino profile images, the browse graphic, and the CSDGM metadata.
The breakdown of the seismic-refleciton profiles is as follows:
