Figure 9. Locations of sites where cores were collected from around Breton Island in July 2014 (Field Activity Number [FAN] 14BIM04) and January 2015 (FAN 2014–336–FA). Basemap derived from USGS bathymetric and lidar data overlaid with National Oceanic and Atmospheric Administration (NOAA) digital elevation model (Love and others, 2010; DeWitt and others, 2016; Terrano and others, 2016b). The channel delineated by deeper depths between Breton and Gosier Islands is the abandoned Mississippi River Gulf Outlet (MRGO). Click on a transect (“T”) or core number to view the core logs for that site. Click here to download map as a printable PDF file.

The sediment data described in this report, including field logs, sample location tables, descriptive core logs, core photographs and x-radiographs, processed grain-size data, and GIS data files with accompanying FGDC metadata, can be downloaded from Bernier and others (2017) or by using the table below. Additionally, the core logs can be viewed by clicking on the transect (push cores) or core number on the sample location map (fig. 9).

Field Activity Collection System (FACS) documents, including scanned handwritten field logs and core logs, are provided in Portable Document Format (PDF) format and can be viewed using the free software Adobe Reader. Digital FACS and field logs were generated from handwritten field notes and logbooks. The core photographs and x-radiographs are provided as high-resolution Joint Photographic Experts Group (JPEG) and TIFF formats, respectively, and can be viewed using standard image viewing software. The sample location tables and grain-size spreadsheets were created in Microsoft Excel 2010 and can be opened using Microsoft Excel 2007 or higher; these data may also be viewed using the free Microsoft Excel Viewer. The sample locations are also provided as comma-separated values text files (.csv) and GIS data files in Esri shapefile (.shp) and Keyhole Markup Language (KML) format; the GIS files can be opened using the free ArcGIS Explorer or Google Earth GIS viewers. All FAN 14BIM04 site locations and GIS data files are referenced to the projected coordinate system North American Datum of 1983 (NAD83), Universal Transverse Mercator (UTM) Zone 16 North (16N); all 2014–336–FA locations and GIS data files are referenced to the projected coordinate system World Geodetic System of 1984 (WGS84), UTM Zone 16N; and all elevations are provided as North American Vertical Datum of 1988 (NAVD88) orthometric heights, derived using the GEOID12A geoid model.
