Topobathymetric Lidar Survey of Breton and Gosier Islands, Louisiana, January 16 and 18, 2014 Topobathymetric Lidar Survey of Breton and Gosier Islands, Louisiana, January 16 and 18, 2014
This dataset contains binary point-cloud data and a Digital Elevation Model (DEM), produced from remotely sensed, geographically referenced topobathymetric measurements encompassing the Breton Island and Gosier Islands, LA study area. The original area of interest was buffered by 100 meters to ensure complete coverage, resulting in approximately 75 square miles of lidar data. The Breton...
A GIS Compilation of Vector Shorelines and Associated Shoreline Change Data for Breton Island, Louisiana: 1869-2014 A GIS Compilation of Vector Shorelines and Associated Shoreline Change Data for Breton Island, Louisiana: 1869-2014
Many barrier islands in the United States are experiencing substantive erosion and elevation loss due to storm surge, waves, and sea-level changes; this is particularly true for the deltaic barrier system in Louisiana. Breton Island is located near the mouth of the Mississippi River in the southern end of the Chandeleur Island chain in southeast Louisiana. This report expands on previous

Effects of proposed sediment borrow pits on nearshore wave climate and longshore sediment transport rate along Breton Island, Louisiana Effects of proposed sediment borrow pits on nearshore wave climate and longshore sediment transport rate along Breton Island, Louisiana
As part of a plan to preserve bird habitat on Breton Island, the southernmost extent of the Chandeleur Islands and part of the Breton National Wildlife Refuge in Louisiana, the U.S. Fish and Wildlife Service plans to increase island elevation with sand supplied from offshore resources. Proposed sand extraction sites include areas offshore where the seafloor morphology suggests suitable...

Near-surface stratigraphy and morphology, Mississippi Inner Shelf, northern Gulf of Mexico Near-surface stratigraphy and morphology, Mississippi Inner Shelf, northern Gulf of Mexico
Over the past decade, the Mississippi Barrier Islands have been the focus of a comprehensive geologic investigation by the U.S. Geological Survey (USGS), in collaboration with the U.S. Army Corps of Engineers (USACE) and the National Park Service (NPS). The islands (Dauphin, Petite Bois, Horn, East Ship, West Ship, and Cat) are part of the Gulf Islands National Seashore (GUIS), and...

Geologic control on the evolution of the inner shelf morphology offshore of the Mississippi barrier islands, northern Gulf of Mexico, USA Geologic control on the evolution of the inner shelf morphology offshore of the Mississippi barrier islands, northern Gulf of Mexico, USA
Between 2008 and 2013, high-resolution geophysical surveys were conducted around the Mississippi barrier islands and offshore. The sonar surveys included swath and single-beam bathymetry, sidescan, and chirp subbottom data collection. The geophysical data were groundtruthed using vibracore sediment collection. The results provide insight into the evolution of the inner shelf and the...

Stratigraphy and morphology of the barrier platform of Breton Island, Louisiana: deltaic, marine and human influences Stratigraphy and morphology of the barrier platform of Breton Island, Louisiana: deltaic, marine and human influences
Breton Island, located at the southern end of the Chandeleur Islands, Louisiana, is part of the Breton National Wildlife Refuge (NWR). Breton NWR is recognized as an important bird habitat and is host to one of Louisiana's largest historical brown pelican nesting colonies. Loss of island area through relative sea-level rise, storm impact, and impeded and diminishing sediment supply is...

Archive of sediment data from vibracores collected in 2010 offshore of the Mississippi barrier islands Archive of sediment data from vibracores collected in 2010 offshore of the Mississippi barrier islands
In 2010, scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center collected sediment cores from coastal waters offshore of the Mississippi barrier islands. With funding support from the Northern Gulf of Mexico (NGOM) Ecosystem Change and Hazard Susceptibility project, 65 subaqueous sediment cores were collected over an area of 480 square kilometers (km2...

From August 13-23, 2013, the U.S. Geological Survey (USGS), in cooperation with the U.S. Army Corps of Engineers (USACE) conducted geophysical surveys to investigate the geologic controls on barrier island framework and long-term sediment transport offshore of Petit Bois Island, Mississippi. This investigation is part of a broader USGS study on Coastal Change and Transport (CCT). These...
