Abstract:

As part of the Barrier Island Monitoring Project, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted nearshore geophysical surveys off Breton and Gosier Islands, Louisiana, in July and August of 2014. To assist the United States Fish and Wildlife Service (USFWS) with restoration planning efforts, the USGS was tasked with answering fundamental questions about the physical environment of the southern Chandeleur Islands, including the geology, morphology, and oceanography. Baseline data needed to answer these questions was either insufficient or missing in the area. The USGS conducted a comprehensive geologic investigation in the summer of 2014 by collecting geophysical and sedimentological data. Breton Island, located at the southern end of the Chandeleur Island chain, Louisiana, was recognized as a natural and globally important nesting sanctuary for several bird species and was established as the Breton National Wildlife Refuge (NWR) in 1904. The aerial extent of Breton Island has diminished 90% since 1920. Land loss is attributed to ongoing relative sea-level rise, diminished sediment supply, and storm impacts. The bird population on Breton Island has also declined over the years, most notably after Hurricane George in 1998 and Hurricane Katrina in 2015, which completely submerged the island. Despite the decreasing habitable acreage, migratory seabirds continue to return and utilize Breton Island. To prevent the island from being completely submerged in the future and to protect, stabilize, and provide more nesting and foraging areas for the birding population, the USFWS is proposing a restoration effort to rebuild Breton Island to its pre-Katrina footprint. This Data Series serves as an archive of processed interferometric-swath, single-beam bathymetry, and side-scan sonar data collected in the nearshore of Breton and Gosier Islands, NWR, Louisiana. The data were collected during two USGS cruises (USGS Field Activity Numbers 2014-314-FA and 2014-317-FA) in July and August 2014. Geographic Information System data products include a 100 meter-cell-size interpolated bathymetry grid surface, trackline maps, and point data files. Additional files include error analysis maps, Field Activity Collection System logs, and formal Federal Geographic Data Committee (FGDC) metadata.

Purpose:

This zip archive contains the survey tracklines in Esri shapefile format for the interferometric bathymetry data collected in July 2014 around the southern Chandeleur Islands, Louisiana.

Supplemental_Information:

Trackline files were recorded at the time of the survey using HYPACK version 14.0.9.47 marine surveying, positioning, and navigation software.

Funds for this report are part of project funds for the Louisiana Outer Coast Early Restoration Project, obtained by the natural resource trustees for the Deepwater Horizon Oil Spill, pursuant to the Framework for Early Restoration Addressing Injuries Resulting from the Deepwater Horizon Oil Spill executed April 20, 2011. USFWS is the project lead for the North Breton Island Barrier Island Restoration project. Acknowledgment of the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center, as a data source would be appreciated in products developed from these data, and such acknowledgment as is standard for citation and legal practices. Sharing of new data layers developed directly from these data would also be appreciated by the U.S. Geological Survey staff. Users should be aware that comparisons with other datasets for the same area from other time periods may be inaccurate, due to inconsistencies resulting from changes in photointerpretation, mapping conventions, and digital processes over time.

Attribute_Accuracy:

Attribute_Accuracy_Report:

The positional accuracy of the tracklines is determined by the accuracy of the Differential GPS correction that the Coda Octopus F190R GPS antennas receive from Marinestar, which is a satellite positioning service, provided by Fugro, Inc. (http://www.fugromarinestar.com/). The tracklines represent the data coverage extent for the interferometric swath bathymetry survey from USGS cruise 14BIM01.

Process_Step:

Process_Description:

The trackline file was created in Esri ArcGIS version 10.2.2.3552 using the XTools Pro extension, version 11.1. The trackline shapefile was created from the x,y,z point data shapefile, using the XTools' feature conversion tool, "make polylines from points". Within XTools' feature conversion selection window, the following items were selected. The "group by field selection" was set to use the HYPACK line name attribute and the "input feature order - order by field" was set to use the FID attribute. The resultant polyline shapefile was then projected in WGS84 Universal Transverse Mercator (UTM) Zone 16 North.
