Data Series 1041
| Survey OverviewA single-beam bathymetric survey was conducted by the USGS St. Petersburg Coastal Marine Science Center within the shallow water coastal zone of south-central Louisiana, during July 22–29, 2015, under Field Activity Number 2015-320-FA (fig. 2). The survey area encompasses 307 square kilometers (km2), covering 64 kilometers (km) of shoreline, extending 4.5 km from the shoreface into the Gulf of Mexico. A total of 1,111.4 line-km of single-beam bathymetry (SBB) data were collected aboard 4 separate survey platform vessels including the 26-foot (ft) R/V Sallenger (cruise identifier 15BIM05, fig. 3), the 17 ft R/V Jabba Jaw (15BIM06, fig. 4), the R/V Shark (15BIM07, fig. 5), and the R/V Chum (15BIM08, fig. 6). Shore-perpendicular survey lines were spaced approximately 450 m apart and shore-parallel crossing lines were located as close to the shoreface as possible, 1 km from the shoreface and again at 4 km offshore (fig. 2). Ellipsoid heights were acquired and processed in the World Geodetic System of 1984 (WGS84) (G1150) Universal Transverse Mercator (UTM) zone 15N. ![]() Figure 2.
