  Description:
    Abstract: 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 five marsh study sites (Sites 5, 6, 7, 8, and 9) and four nearshore estuarine study sites (Sites 8S, 8D, 9S, 9D) along the Point Aux Chenes Bay shoreline of the Grand Bay National Estuarine Research Reserve (GNDNERR), Mississippi. This study builds on Smith and others (2020b) and includes datasets collected after the installation of a living shoreline (a subtidal sill [artificial reef]) that was completed in May 2021. Each marsh 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 three to 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 August 2021 to January 2023. 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 (via loss-on-ignition [LOI]). For select sampling periods, ancillary data (water level, elevation, and vegetation) are also provided in this data release. The estuarine sites consisted of Site 8S (shallow; landward of the subtidal sill), 8D (deep; seaward side of the subtidal sill), as well as 9S and 9D (both sites established adjacent to 8S/8D and the subtidal sill). During select trips water parameters (e.g., waves, water level, and turbidity) were collected at each estuarine site to collect turbidity and wave data. Data presented in this data release were collected under three USGS Field Activities Numbers (FAN; one FAN per year) during thirteen sampling trips (alternate FAN; each sampling trip was assigned a unique alt FAN under the main FAN): 2021-320-FA (21CCT01, 21CCT03, 21CCT04, 21CCT05), 2022-302-FA (22CCT01, 22CCT02, 22CCT03, 22CCT04, 22CCT05, 22CCT06, 22CCT07, 22CCT08) and 2023-301-FA (23CCT01), however, every trip does not contain all data types. This data release also contains data for 2020-323-FA (20CCT02) that was collected as a special collection trip for Hurricane Delta. This data was collected before the subtidal sill was installed and is being published with this data release since pre-subtidal sill data was already published. 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/. Users can look up USGS FANs in the CMGDS by replacing the FAN in the following url: https://cmgds.marine.usgs.gov/services/activity.php?fan=2022-302-FA. Data from a related NST study in the GNDNERR (Middle Bay and North Rigolets) can be found in Smith and others (2020a). Data collected from before the living shoreline (subtidal sill) installation can be found in Smith and others (2020b). For additional information on data processing and analysis, refer to the accompanying journal publication Smith and others (2025). Please read the full metadata for details on data collection, dataset variables, and data quality. 
    Purpose: This dataset, Grand_Bay_RBR_Wave_Data.zip, includes tidal activity measurements obtained from four sampling locations in Grand Bay, Mississippi. RBRsolo3 sensors were used to measure sensor depth, significant wave height, significant wave period, 1/10 wave height, 1/10 wave period, maximum wave height, maximum wave period, average wave height, average wave period, and wave energy. This data was acquired to help researchers better understand the tidal activity in the region.
    Supplemental_Information: USGS scientists collected data from RBRsolo3 sensors during a total of nine surveys. Data were downloaded during quarterly field visits. Each field visit was assigned FAN and alternate FAN (alt-FAN) by USGS staff. This publication contains data for field activities from: 2021-320-FA (21CCT03), 2022-302-FA (22CCT02, 22CCT03, 22CCT04, 22CCT05, 22CCT06, 22CCT07, 22CCT08) and 2023-301-FA (23CCT01). The general site locations were: 8S (30.3370, -88.4462), 8D (30.3359, -88.4441), 9S (30.3353, -88.4471), and 9D (30.3337, -88.4449). Due to technical issues or field constraints, not all sensors were deployed every trip. Due to sensor malfunction, some data may be missing from data files or be presented as "0" values. Users are advised to read the rest of this metadata before using this data. The data are displayed in a comma-separated values (CSV) text file format. Additional sensor details (FAN, site, sensor serial number, deployment and retrieval dates and times, and sensor altitudes) can be found in the "AquaTroll_RBR_sensor_info.csv" file provided within the data download file.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report: The values reported in the data file were recorded by RBRsolo3 (Firmware version 1.041 and 1.056) sensors with an accuracy of ±0.05% (RBR 2020). All other measurements were derived from internal calculations from the sensor, except for sensor altitude and corrected sensor depth that were added to the raw RBR file. Wave data with "0" values are considered null values. See the "QC" field for additional erroneous flagged data. RBRs were used with the factory calibration as users cannot calibrate the RBRs themselves. To ensure sensor accuracy and consistency, sensor intercomparisons were conducted in controlled environments to check that all the RBRs were reading similar information. A datum is not presented for the uncorrected (raw) sensor depth because it is a function of the seawater pressure and seawater density derived using internal calculations. Location data were collected using a handheld Garmin GPSMAP 62stc. Vertical and horizontal positional error was not collected. The precise position of the sensor was not as important as the general location (landward of the subtidal sill, seaward of the subtidal sill). The sensor platform was also marked by several buoys to ensure the platform was easily found for retrieval.
  Logical_Consistency_Report: This dataset includes date and time, burst, depth, sensor altitude, corrected sensor depth, significant wave height, significant wave period, 1/10 wave height, 1/10 wave period, maximum wave height, maximum wave period, average wave height, average wave period, and wave energy from the USGS field activities: 2021-320-FA (21CCT03), 2022-302-FA (22CCT02, 22CCT03, 22CCT04, 22CCT05, 22CCT06, 22CCT07, 22CCT08) and 2023-301-FA (23CCT01). Data were collected in 30-minute intervals. Some data were time shifted from the pre-determined 30-minute interval by several hours due to sensor malfunction and was corrected in post processing.
  Completeness_Report: These data are the complete, uncorrected and corrected (e.g., sensor depth corrected) wave data files for data collected within the Grand Bay National Estuarine Research Reserve, Mississippi. Instrument altitude (length of seabed to the pressure transducer) was measured and can be used to post-process data and correct for depth. This data was minimally processed to remove erroneous data. During quality control steps, potentially erroneous data or data collected when the sensor was out of the water were flagged in the data file and it is recommended not use these sections of data. Wave data with "0" values are regarded as erroneous null data. Data from when the sensor malfunctioned, or the sensor was out of the water (still recording data) were left in the merged data file and were flagged in the "QC" field as "1". These data files are considered complete unless otherwise noted by null data values. For more information, please contact the metadata contact listed in this metadata record.
  Lineage:
    Process_Step:
      Process_Description: An RBRsolo3 sensor was deployed in the Grand Bay estuary to record wave parameters at four estuarine sites. The general site locations were: 8S (30.3370, -88.4462), 8D (30.3359, -88.4441), 9S (30.3353, -88.4471), and 9D (30.3337, -88.4449). The deployment date and time, retrieval date and time, location, sensor serial number, depth at retrieval, and sensor altitude can all be found  in the "AquaTROLL_RBR_sensor_info.csv" file. Location data were collected using a handheld Garmin GPSMAP 62stc. Vertical and horizontal positional error was not collected. The precise position of the sensor was not as important as the general location (landward of the subtidal sill, seaward of the subtidal sill). The sensor platform was also marked by several buoys to ensure the platform was easily found for retrieval. Locations are projected to the World Geodetic System of 1984 (WGS84) coordinate system. Prior to each deployment, the batteries, desiccant and o-rings were replaced, and each sensor was programmed, using the Ruskin software package. Sensors were programmed to record in "wave" mode, at 30-minute intervals with a sampling speed of 4 hertz (Hz) and a sampling duration of 2048 counts. The sampling duration does not relate to the number of rows of data the sensor will report, but instead is the length of data collection per measurement. The sensors were wrapped in plastic wrap then copper foil to prevent biofouling. RBR sensors were mounted vertically to a threaded rod, using hose clamps, attached to a custom-built sensor deployment platform made of starboard and concrete. The RBR was attached so pressure transducers faced the seabed. The sensor altitude (height from the seafloor to the pressure transducer) was collected for use in post-processing. Due to waves and the moving boat, the noted depths in the "AquaTROLL_RBR_sensor_info.csv" file are general depths, as there is some error assumed in the measurements.

      Process_Description: The sensor altitude was used to correct the raw depth measurement. As part of the final QA/QC process, extraneous data recorded pre- and post-deployment (during periods of time when the sensor was collecting data out of the water) were flagged and field names were edited for clarity and consistency. Wave data with "0" values are considered null values. Data from all trips were converted from .txt to .csv files and combined to make one comprehensive data file for each sensor.
