Title:
RBR sensor wave data for two sites in the coastal marsh at Grand Bay National Estuarine Research Reserve, Mississippi, from April 2019 through January 2020
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 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). 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 collected between 2016 and 2017 from a related NST study in the GNDNERR (Middle Bay and North Rigolets) can be found at https://doi.org/10.5066/P9BFR2US. Please read the full metadata for details on data collection, dataset variables, and data quality.

  7. How does the data set describe geographic features?
    Grand_Bay_RBR_Wave_Data.zip
    This file contains CSV files with RBR wave data collected between April 2019 and January 2020 from two sampling sites located in the Grand Bay National Estuarine Research Reserve, Mississippi. Data were collected using two RBRsolo3 sensors (s/n 42048 and s/n 42049). (Source: USGS)
    FAN
    USGS field activity number (FAN) assigned to each sample collection trip. (Source: USGS) Character string. Each field visit was assigned a FAN by the USGS SPCMSC to assist with dataset tracking. It uses the naming convention YYYY-XXX-FA, where YYYY represents the year of field activity, XXX represents the numbered trip, and FA denotes field activity. FANs were used to describe the entire field effort of a project, so alternate FAN's were used to differentiate between quarterly sampling trips.
    Alternate FAN
    Alternate (abbreviated) FAN number assigned each collection trip. (Source: USGS) Character string. Alternate FAN numbers were assigned by the USGS as YYCCTXX, where YY is the 2-digit year, CCT stands for coastal change and transport, and XX is the trip number. No alternate FAN was created for 2019-319-FA; consequently, these empty fields are populated with “---" within the CSV files.

Why was the data set created?

This dataset, Grand_Bay_RBR_Wave_Data.zip, includes tidal activity measurements obtained from two sampling locations in Grand Bay, Mississippi. Two 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 were acquired to help researchers better understand the tidal activity in the region.

How was the data set created?

  1. From what previous works were the data drawn?
  2. How were the data generated, processed, and modified?
    Date: 2019 (process 1 of 5)
    Two RBRsolo3 sensors were used to record wave parameters. RBR s/n 42048 was installed in the estuary between NST Sites 5 and 6 (30.35188496, -88.44801589) and RBR s/n 42049 was installed in the estuary between NST Sites 7 and 8 (30.3414136, -88.44618433). Location are in the North American Datum of 1983 Universal Transverse Mercator Zone 16 North. Before the first deployment in April 2019 (FAN: 2019-319-FA), each sensor was programmed, using the Ruskin software package, to record at 30-minute intervals with a sampling speed of 4 hertz (Hz) and a sampling duration of 1024 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 electrical tape and copper foil to prevent biofouling. A two-meter stainless steel pipe was pushed 1.5 m into the estuary's seabed, leaving 50 centimeters (cm) for the sensor to be attached. The RBR was attached so pressure transducers faced the seabed. The sensor altitude (height from the seafloor to the pressure transducer) was collected for later use in post-processing. For 2019-319-FA, the sensor altitude for RBR 42048 was 14 cm and RBR 42049 was 11.5 cm. Sensor locations were recorded using a real time kinematic global positioning service receiver (RTK GPS) then left to record data for one month. Person who carried out this activity:

    After the initial deployment in April 2019, the RBRs were collected in May 2019. Before removing the sensor, a measurement of the sensor altitude was collected to ensure it did not move during the deployment. The RBRs were then removed from the stainless steel pipe to download the data as a text (.txt) file, clean any biofouling, swap the batteries/desiccant/o-rings, and program the sensors for redeployment.

    During FANs 2019-303-FA (19CCT03 and 19CCT04), and 2020-301-FA (20CCT01) each sensor was programmed to record at 30-minute intervals. The RBRs sampling duration was set to 4096 counts with a sampling speed of 4 hertz (Hz). 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 electrical tape and copper foil to prevent biofouling and were deployed for three-month intervals. The serial numbers were matched with the corresponding locations to ensure consistency between device and location. The RBR was attached so pressure transducers faced the seabed. The sensor altitude (height from the seafloor to the pressure transducer) was collected for later use in post processing. Person who carried out this activity:

    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 removed and field names were edited for clarity and consistency with publishing standards. Data from all four trips were converted from .txt to .csv files and combined to make one comprehensive data file for each sensor. Person who carried out this activity:

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    TThe pressure values reported in Grand_Bay_RBR_Wave_Data.zip were recorded by two RBRsolo3 (Firmware version 1.041) sensors with an accuracy of ±0.05% (RBR 2020). All other measurements were derived from internal calculations from the sensor.
  2. How accurate are the geographic locations?
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    This are complete, uncorrected 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. Data were removed from the file when the RBR was recording measurements out of the water. These data files are considered complete unless otherwise noted by null data values. All data should be checked for accuracy before use.
  5. How consistent are the relationships among the observations, including topology?
    This dataset includes FAN, alternate FAN, time, burst, 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 following trips: 2019-319-FA, 2019-303-FA (19CCT03 and 19CCT04), and 2020-301-FA (20CCT01). 2019-319-FA was not assigned an alternate FAN and is represented as ---. Data was collected in 30 minute intervals. There are 13,305 rows of data for RBR s/n 42048 and 13,408 rows of data for RBR s/n 42049.
