Data Series 1039
| Survey OverviewA single-beam bathymetric survey was conducted by the USGS St. Petersburg Coastal Marine Science Center within the shallow-water coastal zone around the Chandeleur Islands, Louisiana, during June 16‒25, 2015, under Field Activity Number 2015-317-FA (fig. 2). Data were collected aboard 3 separate survey platforms including the 26 foot (ft) R/V Sallenger (cruise identifier 15BIM01, fig. 3), the 17 ft R/V Jabba Jaw (15BIM02, fig. 4), and the R/V Chum (15BIM03, fig. 5), for a total of approximately 1,614 trackline km (table 1). In total, the survey is more than 400 km2, extending 3 km from the back-barrier shoreline of the islands and 5 km from the Gulf shoreface. Shore-perpendicular survey lines were spaced approximately 500 m apart and shore-parallel crossing lines were located as close to the shoreline as possible, 1 km from the shoreline, and 3 km offshore of the Gulf shoreline. All data were collected and processed in the World Geodetic System of 1984 (WGS84) (G1150). ![]() Figure 2.
