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: This dataset contains trackline navigation for 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. This information can help spatially correlate the subbottom data with other data in the GIS.

Logical_Consistency_Report: All subbottom data were collected during USGS cruise 2014-009-FA using an Edgetech SB-512i chirp subbottom profiler. Seismic trackline navigation was generated from unique shot navigation for the seismic system. The unique shot navigation data were evaluated during processing for spurious points; all spurious points were removed prior to generating the trackline navigation. 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 l67f1. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: 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.** The layback routine introduces a stair-step offset in the tie-line seismic shot point and trackline navigation. This is a by-product of the moving median function and appears in the north-south oriented tie-lines. ** Lineage: Source_Information: Source_Citation: Citation_Information: Originator: U.S. Geological Survey Publication_Date: Unpublished Material Title: 512i trackline data Geospatial_Data_Presentation_Form: vector digital data Type_of_Source_Media: disc Source_Time_Period_of_Content: Time_Period_Information: Range_of_Dates/Times: Beginning_Date: 20141020 Ending_Date: 20141026 Source_Currentness_Reference: ground condition Source_Citation_Abbreviation: SEG-Y and JSF 512i data 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 offshore of Fire Island, NY. 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 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 script Read512i_mstk was used to read renumbered and two-trace median filter stacked 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. > 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.

Attributes oldEast and oldNorth in the table 2014-009-512i_lbunique.csv', which is included in the zip compressed version of the shapefile 2014-009-FA_512i_500sht.shp', document pre-layback shot/trace positions. Using Easting and Northing coordinates (UTM Zone 18 N, WGS84) produced in the previous step, the script calculated easting and northing differential values between consecutive 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 with a window length defined by the user (59 traces during 2014-009-FA). Layback easting and northing offsets were calculated by multiplying the linear distance between the catamaran and the shipboard DGPS receiver (43 m during 2014-009-FA) 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 layback routine introduces a stair-step offset in the tie-line seismic shot point and trackline navigation.

Text files containing unique shot point positions for each seismic line with layback-adjusted navigation were concatenated into a comma-delimited text file. Then the layback-corrected position CSV file was imported into ArcMap (version 10.2.2) using 'Add XY data' and saved as points (Geographic, WGS84) in the Esri shapefile format.

The 'FileName' field was used to define which points were used to generate each polyline feature. Additional fields for survey ID, vessel ID, and device ID were added to the attribute table and populated using "Add Field" and "Field Calculator". Using XTools Pro (version 7.1.0) for ArcGIS desktop, the length of each polyline segment was calculated and included in the attribute field 'Length_km', specifying UTM, Zone 18 N, WGS84, and kilometers.
