Archive of Chirp Subbottom Profile Data Collected in 2015 From the Northern Chandeleur Islands, Louisiana Archive of Chirp Subbottom Profile Data Collected in 2015 From the Northern Chandeleur Islands, Louisiana
As part of the Barrier Island Evolution Research Project, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted a nearshore geophysical survey around the northern Chandeleur Islands, Louisiana, in September of 2015. The objective of the project is to improve the understanding of barrier island geomorphic evolution, particularly storm...
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...
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...
Coastal Interferometric Swath Bathymetry Data Collected in 2015 from the Chandeleur Islands, Louisiana Coastal Interferometric Swath Bathymetry Data Collected in 2015 from the Chandeleur Islands, Louisiana
The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC), collected swath bathymetry data at the Chandeleur Islands, Louisiana in September 2015. This USGS Data Release includes the resulting processed elevation point data (xyz) and an interpolated digital elevation model (DEM). For further information regarding data collection and/or processing please...
Cape Canaveral, Florida 2010 Single-beam Bathymetry Data Cape Canaveral, Florida 2010 Single-beam Bathymetry Data
Single-beam bathymetric surveys were conducted on July 27-29, 2010 along 37 cross-shore transects offshore from Cape Canaveral, Fla. The transects were spaced 500 m apart in the alongshore direction and each was approximately 5 km long in the cross-shore.
