Description:

Abstract:: In August of 2013, the U.S. Geological Survey (USGS) conducted geophysical surveys offshore of Petit Bois Island, Mississippi. These efforts are a continued part of the U.S. Geological Survey Gulf of Mexico Science Coordination partnership with the U.S. Army Corps of Engineers (USACE) to assist the Mississippi Coastal Improvements Program (MsCIP) and the Northern Gulf of Mexico (NGOM) Ecosystem Change and Hazards Susceptibility Project, by mapping the shallow geologic stratigraphic framework of the Mississippi Barrier Island Complex.
These geophysical surveys will provide the data necessary for scientists to define, interpret, and provide baseline bathymetry and seafloor habitat for this area to aid scientists in predicting future geomorphological changes to the islands with respect to climate change, storm impacts, and sea level rise. Furthermore, these data combined with the geomorphological results will provide the properties and extent of local offshore sand sediment resources available for planning and execution of the Gulf Islands National Seashore barrier island restoration.
The geophysical data were collected during one cruise (USGS Field Activity Numbers 13CCT04) aboard the University of Southern Mississippi Research Vessel Tommy Munro offshore along the gulf side of Petit Bois Island, Gulf Islands National Seashore, Mississippi. Data were acquired with the following equipment: a Systems Engineering and Assessment, Ltd., SWATHplus interferometric sonar (468 kilohertz (kHz)), an EdgeTech 424 (4-24 kHz), an EdgeTech 525i chirp sub-bottom profiling system, and a Klein 3900 sidescan sonar system.
This report serves as an archive of the processed interferometric swath bathymetry and sidescan sonar data. Geographic information system data products include an interpolated digital elevation model, an acoustic backscatter mosaic, a trackline map, and point data files. Additional files include error analysis maps, Field Activity Collection System logs, and formal Federal Geographic Data Committee metadata.
NOTE: These data are scientific in nature and are not to be used for navigation. Any use of trade names is for descriptive purposes only and does not imply endorsement by the U.S. Government.
Purpose:: This zip archive contains the survey tracklines in ESRI shapefile format for the interferometric bathymetry data collected in August 2013 offshore of Petit Bois Island, Gulf Islands National Seashore, Mississippi
Supplemental_Information:: Trackline files were recorded at the time of the survey using HYPACK version 10.0.5.31 hydrographic acquisition and processing software.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:: The positional accuracy of the tracklines is determined by the accuracy of the raw position data recorded by the GPS antenna during data collection. The tracklines represent the data coverage extent for the interferometric swath bathymetry survey. These trackline data have not been independently verified for accuracy.

Logical_Consistency_Report:

This zip archive contains the interferometric swath bathymetry survey tracklines, recorded at the time of data collection in August 2013. Field logs, vessel platform descriptions, and other survey information are available at https://pubs.usgs.gov/ds/###/facs

Completeness_Report:

This is a complete survey trackline dataset for the interferometric swath bathymetry data collected in August 2013 from offshore of Petit Bois Island, Gulf Island National Seashore.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: Navitaion information was recorded via the CODA Octopus F190R Precision Attitude and Positioning System and differential GPS correction was obtained through the SeaSTAR/OmniSTAR High Performance (HP) broadcast subscription. The raw trackline position data were recorded using HYPACK version 10.0.5.31 hydrographic acquisition and processing software.

Process_Description:

Trackline map creation: The tracklines were exported from HYPACK in Keyhole Markup Language (KML) format and imported into ESRI ArcGIS version 10.1. In ESRI ArcGIS, the trackline data were projected from the GPS acquisition datum (World Geodetic System of 1984, WGS84 G1150) to the North American Datum of 1983 (NAD83), Universal Transverse Mercator (UTM) Zone 16 North and saved to ESRI shapefile format.
