Description:

Abstract:

The influence of tropical and extratropical cyclones on coastal wetlands and marshes is highly variable in both space and time and depends on a number of climatic, geologic, and physical variables. The impacts storms can be either positive or negative with respect to the wetland and marsh ecosystems. Small to moderate amounts of inorganic sediment added during storms or other events helps to abate pressure from sea-level rise. However, if the volume of sediment is large and the resulting deposits thick, the organic substrate may compact causing submergence and a loss in elevation. Similarly, thick deposits of coarse inorganic sediment may also alter the hydrology of the site and impede vegetative processes. Alternative impacts associated with storms include shoreline erosion at the marsh edge as well as potential emergence. Predicting the outcome of these various responses and potential long-term implications can be obtained from a systematic assessment of both historical and recent event deposits. The objectives of this study are to 1) characterize the surficial sediment of the relict to recent washover fans and back-barrier marshes, and 2) characterize the sediment of 6 marsh cores from the back-barrier marshes and a single marsh island core near the mainland. These geologic data will be integrated with other remote sensing data collected along Assateague Island, Maryland / Virginia and assimilated into an assessment of coastal wetland response to storms.

Purpose:

The file includes all site information and water quality parameters collected from each marsh and sandy overwash surface sediment and core sample site collected on Assateague Island and the mainland of Virginia and Maryland in March/April and October 2014 by the U.S. Geological Survey (USGS), St. Petersburg Coastal and Marine Science Center.

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, and Waypoint Product Group's GrafNav and GrafNet, version 8.40).

Logical_Consistency_Report:

This dataset contains the post-processed DGPS coordinates for samples collected during two separate surveys in March and October 2014.

Completeness_Report:

This is a complete processed site information data file for the 2014-301-FA and 2014-322-FA surface sediment time series and core archive.

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 0.00005 seconds latitude and 0.00015 seconds longitude.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_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, 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 standard deviation of the base station ellipsoid height was 0.009 m and the maximum vertical error for the base station was +/- 0.016 m. The time-weighted average positions were compared with the NPS network control numbers for each base station; the time-weighted elevations for each base station occupation were within 2 standard deviations of the NPS control elevations. The NPS control coordinates were used for subsequent post-processing.

Lineage:

Process_Step:

Process_Description:

GPS base stations were erected at multiple National Park Service (NPS) benchmarks located on the back-barrier side of Assateague Island. An Ashtech Z-Xtreme 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 (s) recording intervals throughout the survey. Occupation times at the sample sites ranged from 5 to 30 minutes, and baseline distances to the nearest base station ranged from about 0.5 to 15 kilometers.

Process_Step:

Process_Description:

The NPS control coordinates of the GPS base stations were imported into GrafNav and GrafNet, version 8.4 (Waypoint Product Group) and the data from the rover GPS were post-processed to the concurrent GPS session data from the nearest base station. All S sites (5 minute occupation) sites were post-processed in GrafNav and all M sites (30 minute occupation) were post-processed in GrafNet. The GPS data were acquired and processed in the World Geodetic System of 1984 (WGS84) (G1150) geodetic datum.
