Seismic-reflection data, surficial grab samples and bottom photographs and video were collected along the lower shoreface and inner continental shelf. The purpose of this survey was to assess the impact of Hurricane Sandy on this coastal region. These data were compared to seismic-reflection and surficial sediment data collected by the USGS in the same area in 2011 to evaluate any post-storm changes in seabed morphology and modern sediment thickness on the inner continental shelf. For more information about the WHCMSC Field Activity, see: https://cmgds.marine.usgs.gov/fan_info.php?fan=2014-009-FA. Purpose: PNG images of each seismic profile were generated in order to incorporate images of the seismic profiles into Geographic Information System (GIS) projects and data archives. These data represent approximately 745 km of chirp seismic-reflection data collected by the U.S. Geological Survey during cruise 2014-009-FA offshore of Fire Island, NY. Each profile image can be hotlinked to its corresponding trackline navigation contained within the Esri polyline shapefile '2014-009-FA_512i_Tracklines.shp'. Shotpoint index markers along the top of the PNG images correlate to the positions of 500 shot intervals within the Esri point shapefile '2014-009-FA_512i_500sht.shp' (available from the larger work).

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 l67f1. Positional_Accuracy: 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. Differential Global Positioning System (DGPS) navigation data were acquired with an Ashtech BR2G receiver and recorded with HYPACK (www.hypack.com). The DGPS antenna was located on the aft, port-side of the acquisition van. The SB-0512i was mounted on a catamaran sled and towed at the sea surface approximately 43 m astern of the M/V Scarlett Isabella. Fish depth below water line was 0.5 meters below catamaran floats. The GPS offset from sheave was x = 8.75 m; y = -43 m; z = 0. Navigation data were sent to SonarWiz (version 5) acquisition application and offsets were recorded in the acquisitions software, which logged the coordinates to individual trace headers SEG-Y and JSF format. Layback navigation was generated to account for towfish position. Positional accuracy is assumed to be ± 10 m.

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 250 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 navigation files including trackline shapefiles are summarized below and in the following processing steps. > 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 applied a two-trace median stack (trim 50 percent of the values furthest from the median amplitude) to improve subsequent water bottom picking. > 3. 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. > 4. The Seismic Unix script Plot512i_s creates a swell-filtered PNG image of the seismic profile using supsimage and ImageMagick (version 6.6.1). The resultant images are 29 inches high and contain an 80 millisecond (two-way travel time) window of data. Images show two-way travel time (seconds) along the y-axis (left margin) and distance along profile (in 500 shot intervals, corresponding to the point features in the shapefile 2014-009-FA_512i_500sht.shp) on the x-axis (along top of profile). > Process_Date: 2015 Process_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Wayne Baldwin Contact_Organization: U.S. Geological Survey Contact_Position: Geologist Contact_Address: Address_Type: mailing and physical address Address: 384 Woods Hole Rd.
