The overall objective of this project, which integrates geophysical (bathymetric, seismic, and topographic) and sedimentologic data, is to better understand the depositional and erosional processes that drive the morphologic evolution of barrier islands over annual to interannual timescales (1 to 5 years). Between June 2010 and April 2011, in response to the Deepwater Horizon oil spill, the State of Louisiana constructed a sand berm extending more than 14 kilometers (km) along the northern Chandeleur Islands platform. The construction of the berm provided a unique opportunity to investigate how this new sediment source will interact with and affect the morphologic evolution of the barrier-island system. Data collected from this study will be used to describe differences in the physical characteristics and spatial distribution of sediments both along the axis of the berm and also along transects across the berm and onto the adjacent barrier island. Comparison of these data with data from prior sampling efforts will provide information about sediment interactions and movement between the berm and the natural island platform, improving our understanding of short-term morphologic change and processes in this barrier-island system. This data series serves as an archive of sediment data collected in July 2013 from the Chandeleur Islands sand berm and adjacent barrier-island environments. Data products, including descriptive core logs, core photographs and x-radiographs, results of sediment grain-size analyses, sample location maps, and Geographic Information System (GIS) data files with accompanying formal Federal Geographic Data Committee (FDGC) metadata, can be downloaded from https://pubs.usgs.gov/ds/894/ds894_data.html. Purpose: This zip archive includes the geographic locations, site descriptions, and interpolated elevations in Microsoft Excel format for sediment samples collected in July 2013 from the northern Chandeleur Islands, Louisiana (U.S. Geological Survey Field Activity Number 13BIM05).

Differential Geographic Positioning System (DGPS) coordinates were obtained using post-processing software packages (National Geodetic Survey, NGS, On-Line Positioning User Service, OPUS, and Waypoint Product Group GrafNav, version 8.40). For the five sample sites at which DGPS data were not collected, the positional accuracy of the sample locations is determined by the accuracy of the Garmin GPSMAP 76S handheld Global Positioning System (GPS) receiver used to locate the samples at the time of collection. Logical_Consistency_Report: Sample locations were recorded at the time of collection using a Garmin GPSMAP 76S handheld Global Positioning System (GPS) receiver. The final sample locations, including elevation, are the post-processed DGPS coordinates. Completeness_Report: This dataset includes the locations of 11 surface grab samples and 18 push cores that were collected from the northern Chandeleur Islands in July 2013 (U.S. Geological Survey Field Activity Number, FAN, 13BIM05). As part of a collaborative sampling effort (USGS FAN 13BIM06), an additional 10 push cores were collected from back-barrier marsh and tidal flat sites; sedimentologic and geochemical analysis of those sediments are described in a separate report (U.S. Geological Survey Open File Report 2014-1079). Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: All static GPS base station sessions were processed through the On-Line Positioning User Service (OPUS) maintained by the National Oceanic and Atmospheric Administration (NOAA) and the National Geodetic Survey (NGS). The OPUS base-station solutions were entered into a spreadsheet to compute a final positional coordinate (latitude, longitude, and ellipsoid height). Using the OPUS values and duration of each session, the final position was calculated as a time-weighted average of all GPS sessions. Base-station positional error was calculated as the absolute value of the final position minus the session position value. The maximum horizontal error of the base station coordinates used for post-processing the sample locations was 0.00090 seconds latitude and 0.00027 seconds longitude. All sample locations were post-processed to the final base station coordinates. For the five sample sites at which DGPS data were not collected, sample locations were recorded at the time of collection using a Garmin GPSMAP handheld Global Positioning System (GPS) receiver with a manufacturer's specified accuracy of 3 to 5 meters (95% typical). Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: All static GPS base station sessions were processed through OPUS, and the resulting base-satation solutions were entered into a spreadsheet to compute a final, time-weighted positional coordinate (latitude, longitude, and ellipsoid height). Base-station positional error for each GPS session was calculated as the absolute value of the final position minus the session position value. For this survey, the maximum vertical error for the base station was 0.035 meters. All sample locations were post-processed to the final base station coordinates. For the five sample sites at which DGPS data were not collected, the surface elevations of the sediment samples were interpolated from USGS lidar data collected in July 2013 with a vertical root mean square error (RMSEz) of 0.073 meters.

A Magellan ProFlex 500 GPS receiver recorded the 12-channel full-carrier-phase positioning signals (L1/L2) from satellites via a Thales choke-ring antenna at the base station. A similar GPS instrument combination (Ashtech Z-Xtreme receiver and Ashtech geodetic antenna) was used for the rover GPS. The base receiver and the rover receiver record their positions concurrently at 1-second recording intervals throughout the survey. A rapid-static survey technique was used, with a static occupation duration of 5 minutes at each sample site.
