This work was conducted in support of efforts to map the shoreface, characterize stratigraphy, and investigate changes in seafloor elevations near Fire Island, NY to assess the impacts of Hurricane Sandy to the area in October 2012. Geophysical data were collected as part of the Hurricane Sandy Supplemental Project (GS2-2B). The data release associated with this metadata record serves as an archive of high-resolution chirp sub-bottom trace data and navigation files. Shapefiles (.shp) provided in the data release represent point and polyline vector datasets of Field Activity Number (FAN) 2014-303-FA chirp sub-bottom profile trackline, start of line, and 1,000-shot-interval locations. Purpose: The purpose of the data release described herein is to archive and disseminate digital chirp sub-bottom profile data and associated files collected during USGS FAN 2014-303-FA. Additional survey and data details are available from the USGS Coastal and Marine Geoscience Data System (CMGDS) at, https://cmgds.marine.usgs.gov/fan_info.php?fan=2014-303-FA. Supplemental_Information: Additional survey and data details are available from the Field Activity Collection System (FACS) logs, which are included in the download file, 2014-303-FA_logs.zip.

Field activity planning performed by Cheryl Hapke (former USGS employee), Stan Locker (former USGS employee) and Jennifer Miselis (USGS) in collaboration with Jesse McNinch (former USACE employee) and Heidi Wadman (USACE); data collection conducted by Heidi Wadman (USACE), Jennifer Miselis (USGS), and Jesse McNinch (USACE); and data processing performed by Arnell Forde. This document was improved by scientific/editorial and metadata reviews from Rachel Marcuson and Breanna Williams of the PCMSC and SPCMSC, respectively. Native_Data_Set_Environment: Environment as of Metadata Creation: Microsoft Windows 10 Version 6.2 (Build 9200); Environmental Systems Research Institute (Esri) ArcGIS Pro 3.2.1; MacOS Ventura 13.6.4; Seismic Unix (Release 44); PROJ.5.1.0. Cross_Reference: Citation_Information: Originator: Cohen, J.K. Originator: Stockwell, J.W., Jr. Publication_Date: 2010 Title: Seismic Un*x Release No. 44: An open source software package for seismic research and processing Publication_Information: Publication_Place: Golden, Colorado Publisher: Center for Wave Phenomena, Colorado School of Mines Online_Linkage: https://github.com/JohnWStockwellJr/SeisUnix Data_Quality_Information: Logical_Consistency_Report: These datasets are from one field activity with consistent instrument calibrations. Seismic data were collected during two surveys, which occurred on (Leg 1) June 15-23 and (Leg 2) July 10-12, 2014. Completeness_Report: A total of 106 seismic lines were collected during this field activity. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: As the sub-bottom profile data were acquired, the position of the vessel was continuously determined by a Real-Time Kinematic Global Positioning System (RTK-GPS) utilizing a base/rover setup, which is accurate to within 2 centimeters. Positions from the RTK-GPS were recorded and written to the seismic trace headers approximately every 0.10 seconds, with unique navigation fixes being recorded every second. The approximately 1-meter offset between the chirp and vessel's RTK-GPS antenna has not been accounted for in the comma-delimited American Standard Code for Information Interchange (ASCII) navigation or geospatial files. Lineage: Process_Step: Process_Description: Navigation information was extracted from the seismic trace headers (seismic data available from the data release) using Seismic Unix release 44 software (Cohen and Stockwell, 2010), processed with PROJ.5.1.0 software (https://proj.org/) to generate Universal Transverse Mercator (UTM) Zone 18 North (N) coordinates from latitude and longitude coordinates (World Geodetic System of 1984, WGS84), and then saved as ASCII text files in comma-separated values (CSV) format. Navigation files for each sub-bottom line, saved by line number, were concatenated into comma-delimited text files (.csv) so they could be represented geospatially in geographic information system (GIS) software. The final output files are as follows: (1) 2014-303-FA_nav.csv contains unique shotpoint positions (along each line) for the entire survey, (2) 2014-303-FA_1000sht.csv includes the 1,000-shot-interval locations that were generated to correlate shot locations along the trackline with evenly spaced 1,000-shot index markers along the top of the printable profile images, and (3) 2014-303-FA_sol.csv has the start-of-line locations for each trackline. These CSV files are provided in 2014-303-FA_nav.zip.

The 1,000-shot navigation file, 2014-303-FA_1000sht.csv, provided in the data release was imported into ArcGIS Pro software to produce a geographic representation of the 1,000-shotpoint data collected within the survey area. A 1,000-shot-interval point shapefile (2014-303-FA_1000sht.shp) was generated to correlate shot locations with evenly spaced 1,000-shot index markers along the top of the printable profile images. Likewise, a point shapefile containing the start of line locations for all chirp tracklines, that is based on the reformatted text file 2014-303-FA_sol.csv, was used to create 2014-303-FA_sol.shp. Finally, the 2014-303-FA_nav.csv file containing unique shotpoint positions was imported to ArcGIS Pro to produce a geographic representation of the sub-bottom profile tracklines collected within the survey area. The 'PointsToLine Line (Data Management)' geoprocessing tool was used to create a shapefile (2014-303-FA_trkln.shp) in which individual chirp shotpoints were connected to form tracklines. A non-proprietary version of the shapefiles was created with the 'Map To KML (Conversion)' geoprocessing tool that converted the map document layers to keyhole markup language (KML) format prior to them being compressed (zipped) and saved as a .kmz file (2014-303-FA.kmz). All geospatial files can be found in 2014-303-FA_gis.zip.

The navigation and geospatial files share the same attribute labels and definitions, aside from "FID" and "Shape", which are specific to the .shp files. The detailed attribute descriptions for these files are provided in the data dictionary (DataDictionary_SBP.docx), the metadata are not complete without this file. The survey's trackline file, 2014-303-FA_trkln.shp (106 data records), is a polyline geospatial dataset of all the chirp sub-bottom profile tracklines; 2014-303-FA_1000sht.shp (1408 data records) is a point geospatial dataset representing the 1,000th shot interval; and 2014-303-FA_sol.shp (106 data records) provides the start of each seismic line as a point geospatial dataset.
