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: This dataset contains reflection point navigation for approximately 1,460 km of multi-channel streamer seismic-reflection profiles collected by the U.S. Geological Survey during cruise 2015-001-FA along the Delmarva Peninsula, MD and VA. This information can help spatially correlate the subbottom profiles with other data in the GIS.

Most of the alongshore tracklines were acquired roughly parallel to the orientation of Assateague Island, with crosslines lines running roughly perpendicular to the coast. Line numbering begins at line 1 and ends at line 39. Any spurious data points were removed during processing. There is a starting reflection point (rp) (1) and ending rp (x) with even 100-rp intervals in the shapefile for each seismic trackline. The CSV file contains unique rp navigation. No duplicates exist. 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 no line l6f1. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Differential Global Positioning System (DGPS) and Wide Area Augmentation System (WAAS) GPS navigation data were acquired with a Proflex receiver and a Hemisphere receiver, which were both recorded using HYPACK software (version 14.0.9.47) (www.hypack.com). The DGPS antenna was located on the port-side of the acquisition van. DGPS horizontal positional accuracy is estimated to be within 3-5 m; WAAS enable GPS is estimated to be less than 2 m. The applied acoustics S-Boom source was towed 20-m (lines 1-14) and 25-m (lines 15-39) astern of the M/V Scarlet Isabella. The 100-m long GeoEel 16-channel streamer was towed from the starboard side of the M/V Scarlett Isabella on a 4.82 m boom with 20 m (lines 1-18f1, 37 and 38) and 15 m (lines 18f2-36, 39) of tow cable and 10 m of isolation in front of the start of the active channel. The Geometrics CNT-1 seismic acquisition software (version 5.361) logged the navigation coordinates (in arc seconds) to individual trace headers using the Proflex receiver (JD 161-162) and the Hemisphere receiver (JD 162-168). Layback distance between the GPS antenna and the source and receiver were calculated in post processing. Although horizontal accuracy of navigation positioning is assumed to be within 2 m, inaccuracies likely exceed this value in the seismic reflection data due to uncertainty of azimuths calculated in the layback correction (described in the processing steps).

Source_Citation_Abbreviation: MCS reflection point data Source_Contribution: MCS seismic data were collected using S-Boom source and a 100-m long GeoEel 16-channel streamer. The applied acoustics S-Boom source was towed astern of the M/V Scarlet Isabella at a power level of 400 joules. The Geometrics GeoEel, 16-channel liquid filled digital streamer was towed from the starboard side of the vessel, and the center of the first channel of the active section was 10 to 20 m aft of the boomer source. The streamer had a group interval of 3.25 m connected to Geometrics Streamer Power Supply Unit (SPSU). Data were acquired in Geometrics SEG-D format on Windows PC controller system using Geometrics CNT-1 software. The fire rate was 1 s, the record length was 250 ms and the sample interval was 0.25 ms. Process_Step: Process_Description: A SIOSEIS seismic processing software script (sio_geom) was used as follows: 1. The raw SEG-D shot files were read with the process SEGDDIN specifying the geometrics format; the process HEADER was used to insert time of day into the header based on the start and end times recorded in HYPACK files and from the cruise survey log entries. The process GEOM was used to describe the shot and streamer geometries and to calculate the reflection point (RP) numbers used to gather (sort traces) the seismic line. The process GEOM also set the shot-receiver distance in the trace header of every trace. GEOM type 9 was used for all lines (except for lines 2 to 6 and l30f1) to calculate distances between shots from shot point locations in the SEG-D headers and to bin traces as common RP's (reflection points). GEOM type 6 was specified for lines 2 to 6 (because positions were absent or bad in the header), which computes a distance from last shot (DFLS) for each shot based on the shot time in the header and the navigation from an ASCII file containing time and position. The ASCII navigation file was derived from the HYPACK data and merged with RP files with the Unix join command. The process GATHER was used to sort the shot order traces by the RP numbers (computed by GEOM). A normal move out (NMO) applied a travel time correction to each trace based on time offset and a velocity of 1530 m/s. Lastly, the shot ordered trace gathers were written with the process DISKOX in SEG-Y rev. 1, IEEE floating point format. This step and all subsequent steps were completed by Dave Foster. 2. A SIOSEIS script (sio_gather) was used to sort traces into RP order trace gathers using the RP values calculated by the SIOSEIS process GEOM. RP ordered navigation coordinates to be used in process step 3. 3. A SIOSEIS script (sio_nmo) was used to apply a normal moveout to the RP gathers from step 2. Moveout velocities of 1510 to 1540 m/s were used. 4. A shell script (layback_stack) read the navigation output created in step 2 and extracted the navigation coordinates for channel 1 within each RP. The result was read by a Python script (layback_rp.py) which applied a layback correction (offset from the GPS antenna source and to the midpoint from the source to the first active channel). The script calculated easting and northing differential values between trace positions. Headings between consecutive traces were calculated using the arctangent function (arctan2(dy,dx)), and reciprocal back bearings were determined using a lookup table. Back bearings were smoothed along track using a moving median function. Layback easting and northing offsets were calculated by multiplying the layback distance by the sine and cosine of the smoothed back bearing, respectively. Offset values were then added to the original coordinates to produce layback positions. The script (layback_stack) then called a SIOSEIS script (siostackpop) which stacked the RP gathers and apply a bandpass filter. The process DISKIN read the RP sorted SEG-Y file. The process STACK was used to sum traces, compute the average amplitude for each trace sample, and write the computed samples to one trace. The trace header values of the first trace in the gather were used for the stacked trace. The process FILTER applied a zero-phase bandpass frequency domain filter between 350 and 1800 Hz with a slope of 48 decibel per octave slope. The process HEADER was used to populate the SEG-Y headers with the layback corrected RP coordinates. Lastly, the processed stacked traces were written to disk with the process DISKOX in SEG-Y rev. 1 , IEEE floating point format. The script layback_stack used AWK to format navigation files with unique RP positions and positions for every 100 reflection points in CSV format, which contains attributes for layback corrected UTM Zone 18 coordinates, layback corrected geographic coordinates, line (file) name, year, day, RP number, and fold. Finally, a Python script (GBrptoSQL15001.py) written by Wayne Baldwin, imported the CSV files to the Spatialite (version 3.0.1) enabled SQLite (version 3.7.9) database. Esri shape polyline and shot point files were exported directly from the SQLite database.
