Abstract:
In June/December 2021 and July 2022, the U.S. Geological Survey (USGS) and U.S. Army Corps of Engineers, Engineer Research and Development Center (USACE-ERDC) conducted repeat, nearshore geologic assessments, including bathymetric mapping, near Duck, North Carolina (NC). This work was performed in support of efforts to map the shoreface, characterize stratigraphy, and investigate changes in seafloor elevations near the USACE Field Research Facility and to measure the co-evolution of the morphology and geology of the shoreface before/after a storm and during recovery. Geophysical data were collected as part of the USGS Coastal Sediment Availability and Flux and DUring Nearshore Event eXperiment (DUNEX) projects. 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 Numbers (FANs) 2021-326-FA and 2022-326-FA chirp sub-bottom profile tracklines, start of lines, 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 FANs 2021-326-FA and 2022-326-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=2021-326-FA and https://cmgds.marine.usgs.gov/fan_info.php?fan=2022-326-FA.

Data_Quality_Information:
Logical_Consistency_Report:
These datasets are from three field activities with consistent instrument calibrations. Seismic data were collected during two FANs, which occurred between June 17-18 and December 3-10 of 2021 (2021-326-FA) and July 12-13, 2022 (2022-326-FA).
Completeness_Report:
A total of 60 seismic lines were collected during these field activities. Additional survey and data details are available from the Field Activity Collection System (FACS) logs and acquisition geometry figure, which are included as supplemental information in the download file, DUNEX_logs.zip.
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 0.20 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.

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 so they could be represented geospatially using in geographic information system (GIS) software. The final output files are as follows: (1) 2021-326-FA_nav.csv and 2022-326-FA_nav.csv contain unique shotpoint positions (along each line) for the entire survey, (2) 2021-326-FA_1000sht.csv and 2022-326-FA_1000sht.csv include 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) 2021-326-FA_sol.csv and 2022-326-FA_sol.csv have the start-of-line locations for each trackline. These CSV files are available from the data release, see DUNEX_nav.zip.

Process_Step:
Process_Description:
The reformatted text files referenced in the previous process step were then further processed using Esri ArcGIS Pro 3.2.1 software to generate shapefiles. The 1,000-shot navigation files, 2021-326-FA_1000sht.csv and 2022-326-FA_1000sht.csv, provided in the data release were imported into ArcGIS Pro software to produce a geographic representation of the 1,000-shotpoint data collected within the survey area. 1,000-shot-interval point shapefiles (2021-326-FA_1000shot.shp and 2022-326-FA_1000shot.shp) were generated to correlate shot locations with evenly spaced 1,000-shot index markers along the top of the printable profile images. Likewise, point shapefiles containing the start of line locations for all chirp tracklines, that are based on the reformatted text files 2021-326-FA_sol.csv and 2022-326-FA_sol.csv, were used to create 2021-326-FA_sol.shp and 2022-326-FA_sol.shp. Finally, the 2021-326-FA_nav.csv and 2022-326-FA_nav.csv files containing unique shotpoint positions were imported to ArcGIS Pro to produce a geographic representation of the sub-bottom profile tracklines collected within the survey area. The 'PointsToLine (Data Management)' geoprocessing tool was used to create two shapefiles (2021-326-FA_trkln.shp and 2022-326-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 (DUNEX_2021_2022.kmz). All geospatial files can be found in DUNEX_gis.zip.

Overview_Description:
Entity_and_Attribute_Overview:
Geospatial files (DUNEX_gis.zip): The shapefiles created as part of this dataset are a derivative of the ASCII CSV navigation files provided in DUNEX_nav.zip (organized into individual sub-folders per FAN), which is available from the data release. The navigation and geospatial files mainly share the same attribute labels and definitions, aside from "FID" and "Shape", which are specific to the .shp files. Due to ArcGIS Pro character restrictions, the point shapefile attribute labels were changed to “DOY_HR_MIN” within the attribute tables. 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 trackline files, 2021-326-FA_trkln.shp (44 data records) and 2022-326-FA_trkln.shp (16 data records), are polyline geospatial datasets representing all the chirp sub-bottom profile tracklines; 2021-326-FA_1000shot.shp (151 data records) and 2022-326-FA_1000shot.shp (65 data records) are point geospatial datasets representing the 1,000th shot interval; and 2021-326-FA_sol.shp (44 data records) and 2022-326-FA_sol (16 data records) provide locations for the start of each seismic line as point geospatial datasets.
