These spatial data support research on the Quaternary evolution of the Fire Island coastal system and provide baseline information for research on coastal processes along southern Long Island. For more information about the WHCMSC Field Activity, see https://cmgds.marine.usgs.gov/fan_info.php?fan=2011-005-FA. Purpose: PNG images of each seismic profile were generated in order to incorporate images of the seismic data into Geographic Information System (GIS) projects and data archives. These PNG images represent 2200 kilometers of chirp seismic data collected with an Edgetech Geo-Star FSSB sub-bottom profiling system and an SB-0512i towfish (0.5 - 12 kHz) during USGS field activity 2011-005-FA. The PNG format is universal and yields an easily viewable image of the seismic profiles. Corresponding trackline navigation is contained within a polyline shapefile (2011-005-FA_chirptrk.shp), shot-point locations are available in a point shapefile (2011-005-FA_chirp500sht.shp).

Online_Linkage: http://dx.doi.org/10.1016/j.csr.2015.03.001 Data_Quality_Information: Logical_Consistency_Report: All subbottom data were collected during USGS cruise 2011-005-FA using an Edgetech SB-512i chirp subbottom profiler. Processed chirp seismic data (lines 14 - 92) were converted to PNG format for ease of seismic trace display. Quality control was conducted during processing. Completeness_Report: Acquired chirp seismic data (Lines 14 - 92) were processed and PNG images produced. Only bathymetric data were collected for lines 1 -13, as outlined in the research plan. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The Edgetech SB-0512i was mounted on a catamaran sled and towed at the sea surface 51.5 m (lines l14f1 - l74f1) and 43.2 m (lines l75f1 - l92f1) astern of the M/V Scarlett Isabella. Position data were provided by a Differential Global Positioning System (DGPS) navigation receiver (F180 (lines l14f1 - l74f1) and BR2G (lines l75f1 - l92f1)). Layback navigation was generated to account for towfish position. Positional accuracy is assumed to be ± 10 m.

Final, post-processed profiles were used to make the interpretations. Survey: Survey lines were run at an average speed of 5 knots. Lines 14 through 27 were run at a 75-m line spacing to achieve full coverage of the seafloor with sonar systems in a priority area of interest in the nearshore, in water depths less than 15 meters. Lines 28 through 92 were run at a 150-m line spacing, with the exception of tie lines (lines 52 through 60, 65 through 67, 89 through 92), which were run at approximately a 2-km line spacing. Seismic Data: 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. Chesapeake Technologies' SonarWiz (v.5.03.0016) 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 record DGPS 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 0.25-s shot rate, a 5-ms pulse length, and a 0.5 to 8 kHz frequency sweep. Recorded trace lengths were approximately 200 ms (4340 samples/trace and .000046-s sample interval). Process_Step: Process_Description: Processing Seismic Data: SIOSEIS (version 2010.2.25) was used to read SEG-Y files, renumber shots starting from one, 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. Wayne E. Baldwin performed this and all subsequent process steps. Process_Date: 2011 Process_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Wayne E.

Geographic coordinates (WGS84) were converted to UTM zone 18 coordinates (WGS84) using Proj (version 4.6.0). Header information from each SEG-Y file were saved to text files after an AWK (no version) filter was used to maintain the first and last shots, shots at multiples of 100, and shots with unique navigation coordinates. 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 PNG images. Process_Date: 2011 Process_Step: Process_Description: Seismic Unix (version 4.2) was used to read all processed SEG-Y files and plot the data as 8-bit gray scale Postscript files using the Seismic Unix 'psimage' algorithm. All images were created with a horizontal scale of 200 traces per inch. The profiles contain 60 milliseconds of Two-Way Travel Time within an 12-inch vertical window, yielding approximately 5 milliseconds per inch. Postscript images were converted to PNG format using ImageMagick (version 6.6.1) The x-axis units of the images are shot number while the y-axis is two-way travel time in seconds. Process_Date: 2011 Process_Step: Process_Description: The online links to the data were updated to reflect the new server hosting the data. Additionally, other small edits could be made to the metadata, such as modifying http to https where appropriate. The metadata date (but not the metadata creator) was edited to reflect the date of these changes.
