Coastal Bathymetry Data Collected in 2016 nearshore from West Ship Island to Horn Island, Gulf Islands National Seashore, Mississippi Coastal Bathymetry Data Collected in 2016 nearshore from West Ship Island to Horn Island, Gulf Islands National Seashore, Mississippi
This data release provides 667-line kilometers (km) of processed single-beam bathymetry (SBB) data and 773-line km of processed Interferometric Bathymetry (IFB) collected by the USGS SPCMSC in July 2016 (field activity number [FAN] 2016-347-FA). The IFB were acquired on board the Research Vessel (R/V) Sallenger (subFAN, 16BIM04), and the SBB was acquired on board the R/V Jabba Jaw...

Provided here are the SWAN wave model input of grid 4 with pit 3 configuration and output of significant wave height, dominant wave period, and mean wave direction resulting from simulation of wave scenarios at the Breton Island, LA, as described in USGS Open-File Report 2015-1055 (https://doi.org/10.3133/ofr20151055). There are 128 individual scenarios that are based on significant wave...
Archive of Digitized Analog Boomer Seismic Reflection Data Collected During U.S. Geological Survey Cruise Acadiana 87-2 in the Northern Gulf of Mexico, June 1987 Archive of Digitized Analog Boomer Seismic Reflection Data Collected During U.S. Geological Survey Cruise Acadiana 87-2 in the Northern Gulf of Mexico, June 1987
The U.S. Geological Survey (USGS) Coastal and Marine Geology Program has actively collected geophysical and sedimentological data in the northern Gulf of Mexico for several decades, including shallow subsurface data in the form of high-resolution seismic reflection profiles (HRSP). Prior to the mid-1990s most HRSP data were collected in analog format as paper rolls of continuous profiles...
Single-Beam Bathymetry Data Collected in 2015 Nearshore Dauphin Island, Alabama Single-Beam Bathymetry Data Collected in 2015 Nearshore Dauphin Island, Alabama
Dauphin Island, Alabama is a barrier island located in the Northern Gulf of Mexico that supports local residences, tourism, commercial infrastructure, and the historical Fort Gaines. During the past decade, Dauphin Island has been impacted by several major hurricanes (Ivan, 2004; Katrina, 2005; Isaac, 2012). Storms, along with sea level rise, present a continued threat to island...

Archive of Sediment Data Collected in 2014 and 2015 From Around Breton and Gosier Islands, Breton National Wildlife Refuge, Louisiana Archive of Sediment Data Collected in 2014 and 2015 From Around Breton and Gosier Islands, Breton National Wildlife Refuge, Louisiana
Breton Island, located at the southern end of the Chandeleur Islands, supports one of Louisiana's largest historical brown pelican nesting colonies. Although the brown pelican (Pelecanus occidentalis) was delisted as an endangered species in 2009, nesting areas are threatened by continued land loss and are extremely vulnerable to storm impacts. The U.S. Fish and Wildlife Service proposed...

Analysis of seafloor change at Breton Island, Gosier Shoals, and surrounding waters, 1869–2014, Breton National Wildlife Refuge, Louisiana Analysis of seafloor change at Breton Island, Gosier Shoals, and surrounding waters, 1869–2014, Breton National Wildlife Refuge, Louisiana
Characterizing bathymetric change in coastal environments is an important component in understanding shoreline evolution, especially along barrier island platforms. Bathymetric change is a function of the regional sediment budget, long-term wave and current patterns, and episodic impact from high-energy events such as storms. Human modifications may also cause changes in seafloor...

Analysis of shoreline and geomorphic change for Breton Island, Louisiana, from 1869 to 2014 Analysis of shoreline and geomorphic change for Breton Island, Louisiana, from 1869 to 2014
Many barrier islands in the United States are eroding and losing elevation substantively because of storm surge, waves, and sea-level changes. This is particularly true for the deltaic barrier system in Louisiana. Breton Island is near the mouth of the Mississippi River at the southern end of the Chandeleur barrier island chain in southeast Louisiana. This report expands on previous...

From August 11 to 31, 2014, the U.S. Geological Survey (USGS), in cooperation with the U.S. Fish and Wildlife Service (USFWS), conducted a geophysical survey to investigate the geologic controls on barrier island framework and long-term sediment transport offshore of Breton Island, Louisiana as part of a broader USGS study on Barrier Island Mapping (BIM). Additional details related to...

Integrating geophysical and oceanographic data to assess interannual variability in longshore sediment transport Integrating geophysical and oceanographic data to assess interannual variability in longshore sediment transport
Despite their utility for prediction of coastal behavior and for coastal management, littoral sediment budgets are difficult to quantify over large regions of coastline and over short time scales. In this study, bathymetric change analysis shows differences in the magnitude and spatial location of erosion and accretion over three years; more net accumulation occurred at the littoral end...
