Description:

Abstract:

From June 20-30, 2022, the U.S. Geological Survey (USGS) conducted geophysical surveys to investigate the geologic controls on barrier island evolution and sediment transport near Panama City, Florida (FL). Geophysical data were collected as part of the Coastal Sediment Availability and Flux and Defense Advanced Research Protection Agency (DARPA) Reefense projects. This shapefile represents a point dataset of field activity number (FAN) 2022-312-FA chirp subbottom profile 1,000-shot-interval locations.

Purpose:

To aid in the registering of digital chirp subbottom profile data collected during USGS FAN 2022-312-FA.

Supplemental_Information:

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=2022-312-FA and in the Field Activity Collection System (FACS) logs, which are included in the download file, 2022-312-FA_logs.zip (Forde and others, 2023).

Data_Set_Credit:

Data collection and processing were performed by Chelsea Stalk, Emily Wei, and Arnell Forde of the USGS St. Petersburg Coastal and Marine Science Center.

Native_Data_Set_Environment:

Environment as of Metadata Creation: Microsoft Windows 10 Version 6.2 (Build 9200); Environmental Systems Research Institute (Esri) ArcMap 10.8.2.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The validity or accuracy of marine subbottom profiles is highly qualitative and depends on equipment and operating condition variables. Visual inspection of the images rendered from the data did not show any major anomalies.

Logical_Consistency_Report:

This dataset is from one field activity with consistent instrument calibrations.

Completeness_Report:

A total of 234 seismic lines were collected during this field activity. Ten lines were excluded from Forde and others (2023), due to equipment or acquisition issues resulting in partial or unusable data files.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

As the subbottom profile data were acquired, the position of the vessel was continuously determined by an Applanix POS MV Wavemaster II inertial aided navigation system (IANS), which is accurate to within 0.5-2 meters (m). Positions from the POS MV IANS were recorded and written to the seismic trace headers every 0.20 seconds, with unique navigation fixes every 1 second. The approximately 3-meter offset between the chirp and vessel's IANS reference point has not been accounted for in the comma-delimited American Standard Code for Information Interchange (ASCII) navigation files and trackline map.

Lineage:

Process_Step:

Process_Description:

Navigation files were extracted from the seismic trace headers using Seismic Unix release 44 software, processed with PROJ.5.1.0 software to generate Universal Transverse Mercator (UTM) Zone 16 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.

Process_Step:

Process_Description:

The reformatted text files were imported into Esri ArcMap 10.8 software to produce a geographic representation of the shotpoint data collected within the survey area. A 1,000-shot-interval point shapefile was generated to correlate shot locations on the trackline map with evenly spaced 1,000-shot index markers along the top of the printable profile images.

Attribute_Domain_Values:

Unrepresentable_Domain:

Line numbers were assigned by the EdgeTech 3400 chirp topside unit during data acquisition and are composed of the FAN, DOY, and trackline number. The naming convention used for each subbottom line is as follows: x_env, where 'x' is an alphanumeric number indicating a specific trackline (for example, 2022_312_FA_171_001) and 'env' denotes that the seismic traces were output as an envelope. Four track lines were manually assigned and do not follow this convention. For these files, the DOY information is excluded from the line number (for example, 2022_312_FA_001b_env). 26 test and “tie” lines (perpendicular tracklines crossing two parallel lines) also deviate from the previously described naming convention and have names such as, 2022_312_FA_172_014testDv5_env and 2022_312_FA_171_004tie_env.
