To better understand sediment deposition in marsh environments, scientists from the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center (USGS-SPCMSC) selected four study sites (Sites 5, 6, 7, and 8) along the Point Aux Chenes Bay shoreline of the Grand Bay National Estuarine Research Reserve (GNDNERR), Mississippi. 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 six 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, and wave data) are also provided in this data release. Data were collected during USGS 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).

This dataset, Grand_Bay_RBR_Data.zip, contains water parameter and tidal data obtained from two sampling locations in Grand Bay, Mississippi. Two RBRsolo3 sensors were used to measure tidal slope, atmospheric/sea pressure, and sensor depth. Wave data collected by RBRSolo2 sensors are also provided in this data release within the download file, Grand_Bay_RBR_Wave_Data.zip. These data were acquired to help researchers better understand the tidal activity in the region.
USGS scientists collected data from RBR sensors during a total of four surveys from April 2019 to January 2020. Data were downloaded during quarterly field visits. Each field visit was assigned a FAN and sub-FAN by USGS staff. This publication contains data for field activities from: 1) 2019-319-FA (April 2019-May 2019), 2) 2019-303-FA (19CCT03, May 2019-August 2019; 19CCT04, August 2019-November 2019), 3) 2020-301-FA (20CCT01, November 2019-January 2020). RBR serial number (s/n) 42048 was located between NST Sites 5 and 6 (30.35188496, -88.44801589), RBR s/n 42049 was located between NST Sites 7 and 8 (30.3414136, -88.44618433). The data are displayed in a comma-separated values (CSV) text file format. Additional sensor details (deployment dates, sensor altitudes) can be found in the supplemental file (Supplemental_RBR_Data.csv) and associated data dictionary, provided within the data download file.
