Abstract:
Microfossil (benthic foraminifera) data from coastal areas were collected from state and federally managed lands within the Grand Bay National Estuarine Research Reserve and Grand Bay National Wildlife Refuge, Grand Bay, Mississippi/Alabama; federally managed lands of Bon Secour National Wildlife Refuge on Cedar Island and Little Dauphin Island, Alabama; and municipally managed land around Dauphin Island, Alabama. Samples were analyzed and quantified for foraminiferal census in order to document changes to the coastal wetlands, estuarine environments, and to aid in paleoenvironmental reconstruction. These data provide a baseline dataset for use in future wetland change descriptive and predictive studies and assessments. The data presented here were collected as part of the U.S. Geological Survey’s Sea-level and Storm Impacts on Estuarine Environments and Shorelines (SSIEES) project (https://coastal.er.usgs.gov/ssiees), Barrier Island Evolution Research (BIER) project (https://coastal.er.usgs.gov/bier), and National Fish and Wildlife Foundation-funded Alabama Barrier Island Restoration Feasibility Study (a collaborative study between the U.S. Army Corp of Engineers, Mobile District; the State of Alabama; and the USGS [https://www.usgs.gov/centers/spcmsc/science/alabama-barrier-island-restoration-study]). These projects aim to assess ecological and societal vulnerability that results from long- and short-term physical changes to barrier islands and coastal wetlands. Two sampling surveys were conducted between 2014 and 2015: 14CCT01 (15–19 September 2014; 2014-323-FA), and 15BIM09 (18–20 August 2015; 2015-322-FA). During those two trips, seven Russian peat auger cores were taken from marsh locations. Three cores from Dauphin Island were subsampled and stained with rose Bengal (rB) in the field to indicate life. Four further cores from Dauphin Island and Grand Bay were not stained. At the St. Petersburg Coastal and Marine Science Center all cores were subsampled resulting in a total of 74 subsamples. Samples were processed in the laboratory to four size fractions (63–125 μm, 125–250 μm, 250–850 μm, and >850 μm), of which the 125–250 μm and 250–850 μm fractions were picked at equal proportions of total sample and reported combined (125–850 μm). For additional information regarding foraminiferal collection and/or processing methods, refer to Ellis and others (2017). Further data collected on and surrounding Dauphin Island is presented in Ellis and others (2017) and Ellis and others (2018).
Purpose:
Dissemination of benthic foraminiferal assemblage count data from subsurface sediment samples collected from eastern Mississippi Sound between September 2014 and August 2015. This dataset, MS_AL_Cores_XYZ.csv, includes processed coordinate and elevation data collected at each sample location.
Supplemental_Information:
To ensure that USGS-St. Petersburg data management protocols were followed, each survey was assigned the following USGS field activity number (FAN): 2014-323-FA (September 2014, Project ID 14CCT01), and 2015-322-FA (August 2015, Project ID 15BIM09). Additional survey and data details are available from the U.S. Geological Survey Coastal and Marine Geoscience Data System (CMGDS) at, http://cmgds.marine.usgs.gov/.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_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_Consistency_Report:
This dataset contains the post-processed GPS and DGPS coordinates for samples collected during two separate surveys in 2014 and 2015. Sample locations were recorded at the time of collection using two Asthech Z-Extreme SMG-ZX-3 receivers (and others), one at a benchmark base-station and one roving in the field.
Completeness_Report:
This dataset includes the locations of 7 marsh sediment cores collected in Grand Bay (Mississippi) and Dauphin Island (Alabama).
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
All static 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), and the results 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. 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_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
All static base station sessions were processed through OPUS maintained by NOAA and the NGS. The base location results from OPUS 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 standard deviation or the base station ellipsoid height was 0.014 meters (m) and the maximum vertical error for the base station was +/- 0.015 m. All sample locations were post-processed to the base station coordinate.

Process_Step:
Process_Description:
A GPS base station was erected for each sampling survey at a NGS benchmark located closest to the survey's sampling sites. DGPS receivers recorded the 12-channel full-carrier-phase positioning signals (L1/L2) from satellites via the Thales choke ring antenna on the base station and an Ashtech Geodetic antenna on the rover. This DGPS instrument combination was duplicated on the rover unit. The base station 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_Description:
The coordinate values of the GPS base station are the time-weighted average of values obtained from OPUS. The base station coordinates were imported into GrafNav and GrafNet (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.
