<p>On July 5–19 (cruise 13BIM02) and August 22–September 1 (cruise 13BIM07), 2013, the <abbr title="United States">U.S.</abbr> Geological Survey (<abbr title="U.S. Geological Survey">USGS</abbr>) conducted geophysical surveys to investigate the geologic controls on barrier island evolution and medium-term and interannual sediment transport along the oil spill mitigation sand berm constructed at the north end and offshore of the Chandeleur Islands, Louisiana. This investigation is part of a broader <abbr title="U.S. Geological Survey">USGS</abbr> study, which seeks to understand barrier island evolution better over medium time scales (months to years). This report serves as an archive of unprocessed digital chirp subbottom data, trackline maps, navigation files, Geographic Information System (<abbr title="Geographic Information System">GIS</abbr>) files, Field Activity Collection System (<acronym title="Field Activity Collection System">FACS</acronym>) logs, and formal Federal Geographic Data Committee (<abbr title="Federal Geographic Data Committee">FGDC</abbr>) metadata. Gained–showing a relative increase in signal amplitude–digital images of the seismic profiles are provided.
