Each site consisted of four plots located along a transect perpendicular to the marsh-estuary shoreline at 5-meter (m) increments (5, 10, 15, and 20 m from the shoreline). Each plot contained four net sedimentation tiles (NST) that were secured flush to the marsh surface using polyvinyl chloride (PVC) pipe. NST are an inexpensive and simple tool to assess short- and long-term deposition that can be deployed in highly dynamic environments without the compaction associated with traditional coring methods. The NST were deployed for three months, measuring quarterly sediment deposition for one year from October 2016 to October 2017. In addition, three NST were deployed at the 10-m plot on October 5th prior to the landfall of Hurricane Nate (October 8, 2017) and retrieved after 12 days, providing measurements of storm deposition. Sediment deposited on the NST were processed to determine physical characteristics, such as deposition thickness, volume, wet weight/dry weight, and organic content (loss-on-ignition [LOI]). When available, additional data collected at each site including water level, elevation, and turbidity data are provided in this data release. Data were collected during Field Activities Numbers (FAN) 2017-303-FA, 2017-315-FA, 2017-333-FA, 2017-346-FA, and 2017-363-FA (also known as subFANs 17CCT01, 17CCT02, 17CCT03, 17CCT04, and 17CCT05, respectively). Additional survey and data details are available from the U.S. Geological Survey Coastal and Marine Geoscience Data System (CMGDS) at, https://cmgds.marine.usgs.gov/. Please read the full metadata for details on data collection, data set variables, and data quality. Purpose: This data release contains elevation data for shorelines, net sedimentation tile plots, elevation benchmarks, and water level logger wells. Elevation data can be used in conjunction with in-situ sedimentation data to track lateral erosion and accretion of the marsh and estuary surface. Elevation data were collected using a total station and differential Global Positioning System (DGPS). Data should not be used for navigational purposes. Supplemental_Information: USGS scientists collected sediment samples and shore profiles from Grand Bay, Mississippi during a total of six surveys from October 2016 to October 2017 (USGS Field Activity Numbers (FAN) 16CCT07, 17CCT01, 17CCT02, 17CCT03, 17CCT04, and 17CCT05). Samples were collected from four survey sites, which host a variety of depositional and eroding environments, including eroding marsh edges, tidal creek, and sheltered estuarine environments. Site 1 is located at the mouth of Bayou Heron, the main access channel for Grand Bay. Site 2 is located on an eroding marsh edge in the south-western portion of the Middle Bay (North Rigolets Island) . Site 3 is a protected marsh edge located in the north western portion of Middle Bay, and Site 4 is located along a large tidal channel in the far south-western area of the survey extent. Position and elevation data were recorded using Ashtech DGPS receivers and Global Navigation Satellite System (GNSS) antennas. A stop-and-go rapid-static survey technique was used with static occupations at each survey point, with a recording interval of 1 s. Two additional DGPS receivers, recorded concurrent static data at benchmark locations within the Grand Bay National Estuarine Research Reserve (GBNERR): National Geodetic Survey (NGS) Permanent Identifier [PID]DO5987, stamping 0166 B 2010 (recording site name B166) located at the boat ramp at the northern end of Bayou Heron, and NGS PID DO5977, stamping S 189A 2012 (recording site name 189A) located near the railroad tracks at the entrance of the Refuge. The differential positioning of all acquired survey points was obtained through the post processing of the rover data to the base station data using GrafNav version 8.6 (Waypoint Product Group). This dataset was transformed from the North American Datum of 1983 (NAD83) acquisition datum and ellipsoid height, to NAD83 and North American Vertical Datum of 1988 (NAVD88) orthometric height using the GEOID 12A model (NOAA NGS VDatum software version 3.6 - http://vdatum.noaa.gov/).

Online_Linkage: https://scholarcommons.usf.edu/etd/7371/ Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The positional accuracy of the sample locations is determined by the accuracy of the raw position data recorded by the GPS and antenna during data collection. DGPS coordinates were obtained using post-processing software packages (National Geodetic Survey On-Line Positioning User Service (OPUS), and Waypoint Product Group GrafNav, version 8.6. Water level readings were corrected to NAVD88 and compared to a nearby National Oceanic and Atmospheric Administration (NOAA) water level station. The total station only provides elevation measurements and does not produce positional data; therefore, no positional data were reported for those samples. The random surface samples (R) were collected using an angle and distance from the bead plot. The angles and distances were reported in the notes section and were approximate locations and should not be considered precise positions. If positions are desired the reader is requested to contact the authors for more information. Logical_Consistency_Report: Position and elevation data at each sample site were recorded with Ashtech DGPS receivers and GNSS antennas. Additionally, DGPS data were recorded concurrently throughout the survey at two NGS benchmarks using a similar instrument combination. Due to a local base station malfunction during survey 17CCT05, the nearest Continually Operating Reference Station (CORS) ALDI (PID=DL3486), located on the east end of Dauphin Island, Alabama, was utilized for post-processing. The final sample locations, including elevation, are the post-processed DGPS coordinates processed to the nearest base station; baseline distances for all sample sites were approximately less than 9 kilometers (km), sample elevations from survey 17CCT05 have a baseline upwards of 30 km. Total station samples do not include occupation times, collection times, positional data, or horizontal errors. The random surface samples (R) collected with the total station do not include verified elevations and should be used with caution. Completeness_Report: This dataset includes the locations of 1,236 elevation points collected from shorelines, water level logger wells, elevation benchmarks, random surface samples, and net sedimentation tile study sites that were collected from Grand Bay Mississippi from October 2016 to October 2017 (USGS FANs 16CCT07, 17CCT01, 17CCT02, 17CCT03, 17CCT04, and 17CCT05). This dataset is considered complete for the information presented, as described in the abstract section. Users are advised to read the rest of the metadata record carefully for additional details. In some cases, sensor malfunctions or significant errors caused data loss for some sites or FANs. During 17CCT01 a total station was used in some cases and there is no occupation time, collection time, easting, northing, latitude, longitude, verified elevations, or horizontal error. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: All static GPS base station sessions were processed through the OPUS maintained by NGS. The OPUS base station solutions were entered into a spreadsheet to compute a final, time-weighted positional coordinate (latitude, longitude, and ellipsoid height) for each base station. 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 were 0.00081 s latitude and 0.00063 s longitude for B166, and 0.00054 s latitude and 0.00036 s longitude for 189A. The time-weighted positions for both base stations were compared against the derived coordinates from the first survey (16CCT07). All subsequent survey occupations (17CCT01-17CCT05 produced time weighted averages that were within 3 standard deviations of the first occupation and therefore, for consistency, the 16CCT07 coordinates were used in all post-processing. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: All static GPS base station sessions were processed through OPUS. The OPUS base station solutions were entered into a spreadsheet to compute a final, time-weighted positional coordinate (latitude, longitude, and ellipsoid height) for each base station. Base station positional error for each GPS session was calculated as the absolute value of the final position minus the session position value. For all base station occupations, the maximum standard deviations of the base station ellipsoid heights were 0.021 m for B166, 0.012 m for 189A and the maximum vertical errors for the base stations were 0.028 m and 0.029 m, respectively. The time-weighted positions for both base stations were compared against the derived coordinates from the first survey (16CCT07), which individually has a standard deviation of 0.007 m (B166) and 0.011 m (189A). All subsequent survey occupations (17CCT01-17CCT04) produced time weighted averages that were within 3 standard deviations of the first occupation and therefore, for consistency, the 16CCT07 coordinates were used in post-processing. Data acquired during survey 17CCT05 was post-processed using data downloaded from the NGS website for CORS station ALDI (https://www.ngs.noaa.gov/CORS/Sites/aldi.html). The station is located approximately 30 km away from the survey location, causing significant errors due to extended baseline distance. Total station samples are referenced to a benchmark at each of the study sites. Lineage: Process_Step: Process_Description: GPS base stations were erected on two NGS benchmarks located within the Grand Bay National Estuarine Research Reserve (GBNERR), B166 (PID DO5987) and 189A (PID DO5977). Ashtech Z-Xtreme DGPS receivers recorded the 12-channel full-carrier-phase positioning signals (L1/L2) from satellites via a Thales choke-ring antenna at the base stations. A similar instrument combination (Ashtech Z-Xtreme receiver and Ashtech GNSS antenna) was used for the rover GPS systems. The base receiver and the rover receiver record their positions concurrently at 1 s recording intervals throughout the survey. A stop-and-go rapid-static survey technique was used, with a static occupation. For FAN 17CCT01, total station measurements were collected instead of using DGPS . The total station measures the sloping distance of an object to the instrument. A temporary USGS-installed benchmark was surveyed before collecting marsh data to get a static reference point. This reference point was then used to determine elevation for the rest of the samples. Process_Date: 2017 Process_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Chelsea A.
