As part of the Barrier Island Evolution Research (BIER) project, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) collected sediment samples from the northern Chandeleur Islands in March and September 2012. 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 subsequent 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 March and September 2012 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 http://pubs.usgs.gov/ds/0850/html/ds850_data.html.
This zip archive includes the sample locations in Esri shapefile format for sediment samples collected in March 2012 from the northern Chandeleur Islands, Louisiana (U.S. Geological Survey Field Activity Number 12BIM01).

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.
Sample locations were recorded at the time of collection using a Garmin GPSMAP 76S handheld Global Positioning System (GPS) receiver.
This dataset includes the locations of 29 surface grab samples, 10 submerged grab samples, and 31 push cores that were collected from the northern Chandeleur Islands in March 2012 (U.S. Geological Survey Field Activity Number 12BIM01). During the same sampling effort, an additional 15 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 Data Series 850).
Sample locations were recorded at the time of collection using a Garmin GPSMAP handheld Global Positioning System (GPS) receiver.
