  Description:
    Abstract:
      Scientists from the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center collected shallow sediment cores and surface samples from a coastal salt marsh environment next to Vermilion Bay in southwest Louisiana in January 2013. The sampling was part of a larger USGS study to gather data for assessing environmental changes over the past 150 years. The objective of the study was to expand upon the historical context of sea level and storms affecting coastal systems and how these systems might change under persistent or varying conditions. The data from this report add to a regional environmental change database that aids with the continuing effort to understand the evolution of coastal systems. 
      This report serves as an archive for sedimentological, radiochemical, and microbiological data derived from the sediment cores and surface samples. Data is available for the sampling period in January 2013. Data is available in downloadable spreadsheet, Joint Photographic Experts Group (JPEG) and Portable Document File (PDF) formats. Additional files included: ArcGIS shape files of the sample locations, detailed results of sediment grain size analyses, and formal Federal Geographic Data Committee (FDGC) metadata.
    Purpose: This dataset, 13CCT01+AF8-Core+AF8-Location.xlsx, includes the geographic locations and site information in Microsoft Excel format for sediment samples collected January, 19 2013 from Vermilion Bay in southwest Louisiana (U.S. Geological Survey Field Activity Number 13CCT01).
    Supplemental+AF8-Information: This publication contains data collected during field activity number (FAN) 13CCT01. For additional information associated with the activity, please go to http://cmgds.marine.usgs.gov/fan+AF8-info.php?fan+AD0-13CCT01.

Data+AF8-Quality+AF8-Information:
  Attribute+AF8-Accuracy:
    Attribute+AF8-Accuracy+AF8-Report: The positional accuracy of the sample locations was determined by the accuracy of the raw position data recorded by the GPS antenna during data collection. Differential Geographic Positioning System (DGPS) coordinates were obtained using post-processing software packages (National Geodetic Survey's On-Line Positioning User Service (OPUS), version 2.2 and Waypoint Product Group's GrafNav and GrafNet, version 8.30).
  Logical+AF8-Consistency+AF8-Report: This dataset contains the post-processed DGPS coordinates for samples collected during field work in January 2013. 
  Completeness+AF8-Report: This is a complete, processed site location data file for the 13CCT01-M01, 13CCT01-M02, and 13CCT01-M03 marsh core archive. 
  Positional+AF8-Accuracy:
    Horizontal+AF8-Positional+AF8-Accuracy:
      Horizontal+AF8-Positional+AF8-Accuracy+AF8-Report: All static base station sessions were processed through On-Line Positioning User Service (OPUS) maintained by the National Oceanic and Atmospheric Administration (NOAA) and the National Geodetic Survey (NGS), and the results were entered into a spreadsheet to compute a final, time-weighted positional coordinate (latitude, and longitude). Base-station positional error for each GPS session 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 0.00018 seconds latitude and 0.00045 seconds longitude.
    Vertical+AF8-Positional+AF8-Accuracy:
      Vertical+AF8-Positional+AF8-Accuracy+AF8-Report: All static base station sessions were processed through OPUS maintained by the National Oceanic and Atmospheric Administration (NOAA) and the National Geodetic Survey (NGS). The base location results from OPUS were entered into a spreadsheet to compute a final, time-weighted positional coordinate (latitude, and longitude). 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 standard deviation or the base station ellipsoid height was 0.006 m and the maximum vertical error for the base station was  0.021 m. All sample locations were post-processed to the base station coordinates. 
  Lineage:
    Process+AF8-Step:
      Process+AF8-Description: A GPS base station was erected at a temporarily installed USGS benchmark (TMRK). GPS receivers recorded the 12-channel full-carrier-phase positioning signals (L1/L2) from satellites via the Thales choke-ring antenna. This GPS instrument combination was duplicated on the rover GPS. The base receiver and the rover receiver record their positions concurrently at 1-second (s) recording intervals throughout the survey. Occupation times at the sample sites ranged from 5 to 30 minutes.

    Process+AF8-Step:
      Process+AF8-Description: The coordinate values of the GPS base station (TMRK) are the time-weighted average of values obtained from the National Geodetic Survey On-Line Positioning User Service (OPUS). The base station coordinates were imported into GrafNav and GrafNet, version 8.3 (Waypoint Product Group) and the GPS data from the rover were post-processed to the concurrent GPS session data at the base station. The GPS data were processed and exported in the World Geodetic System of 1984 (WGS84) (G1150) geodetic datum.
