These datasets were collected to serve as baseline data prior to the installation of a living shoreline (a subtidal sill). Each site consisted of five plots located along a transect perpendicular to the marsh-estuary shoreline at 5-meter (m) increments (5, 10, 15, 20, and 25 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 month sampling periods, measuring sediment deposition from July 2018 to January 2020, with one set of NST being deployed for six months. Sediment deposited on the NST were processed to determine physical characteristics, such as deposition thickness, volume, wet weight/dry weight, grain size, and organic content (loss-on-ignition [LOI]). For select sampling periods, ancillary data (water level, elevation, turbidity, and wave data) are also provided in this data release. Data were collected during Field Activities Numbers (FAN) 2018-332-FA (18CCT01), 2018-358-FA (18CCT10), 2019-303-FA (19CCT01, 19CCT02, 19CCT03, and 19CCT04, respectively), and 2020-301-FA (20CCT01). 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/. Data from a related NST study in the GNDNERR (Middle Bay and North Rigolets) can be found at https://coastal.er.usgs.gov/data-release/doi-P9BFR2US/. Please read the full metadata for details on data collection, dataset variables, and data quality. Purpose: Vegetation species and abundance data can provide important information on the health of a marsh. Vegetation surveys were conducted within each NST plot (1 square meter) during the 19CCT02 and 20CCT01 trips. Within each plot the average vegetation canopy height was measured, a percent cover for each species was estimated, and a sub-sampled stem count of each species from 1/16th of a meter of the plot was collected. Supplemental_Information: Data was collected through two field visits. Each field visit was assigned a field activity number (FAN) and sub-FAN by the U.S Geological Survey (USGS). This publication contains data for field activities from: 1) 2019-303-FA (19CCT02, May 2019), and 2) 2020-301-FA (20CCT01, January 2020).

Completeness_Report: This is a complete, vegetation survey data file for data collected within the Grand Bay National Estuarine Research Reserve, Mississippi. Lineage: Process_Step: Process_Description: Four previously established study sites (Sites 5, 6, 7, and 8) containing net sedimentation tiles (NST) within the Grand Bay National Estuarine Research Reserve, Mississippi were used to collect vegetation data. NST plots (a 1 square meter plot) were located at 5, 10, 15, 20 and 25 m inland and perpendicular to the shoreline. Vegetation surveys were conducted by Grand Bay National Estuarine Research Reserve staff in 19CCT02 (May 2019) and 20CCT01 (February 2020) using NERR system wide monitoring protocols (Moore, 2009). First, a 1 square meter quadrat was placed on the corner PVC markers of the plot to ensure the quadrat covered the study area. To collect percent cover, the observer looked at the whole plot, then visualized that all of one species were gathered together and pushed to once side of the quadrat (if it appears that three-quarters of the quadrat is covered, then the percent cover for that species is 75%). This was repeated for each of the vegetation species, making sure that the overall sum of percent cover with species was not greater than 100%. To collect canopy height, a pole marked at 25-centimeter (cm) intervals was used to estimate the average height of the vegetation within the plot. To collect stem densities, the quadrat was marked at 1/16th of a meter in the upper right corner. Within the smaller quadrat area, the number of stems for each species were counted. Field sheet data was then transferred to comma separated value (CSV) file for publication.
