Title: Moisture Probe Location and Elevation Data for January 25, 2023
Abstract:
Five Sentek® TriSCAN® moisture probes were installed at Madeira Beach, Florida, on January 25, 2023, to collect hourly observations of sediment moisture content, salinity, and temperature. The probes extend down 90 centimeters (cm) below the surface. The data file included in this data release contains the locations (easting, northing, and elevation) of the five probes, as well as the standard deviation in each measurement from the Global Positioning System (GPS) survey. For more information about the data obtained from the probes, please see the Moisture_Probe data and metadata files included in this data release.
Supplemental_Information:
Following U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) data management protocols, these data were assigned USGS field activity number (FAN), 2023-314-FA. Additional survey and data details are available on the Coastal and Marine Geoscience Data System (CMGDS) at https://cmgds.marine.usgs.gov/services/activity.php?fan=2023-314-FA.

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: 25-Jan-2023 (process 1 of 1)
    Moisture probe locations were determined using a HYPACK® real-time kinematic (RTK) GPS system by collecting continuous measurements for 1-minute each at each probe location. The mean and standard deviations of the measurements at each probe was also calculated. For more information on the GPS survey data collection and processing methods used, refer to Brown and others (2018). 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?
  2. How accurate are the geographic locations?
    The horizontal accuracy of the post-processed kinematic GPS data is +/- 2 cm, based on the accuracy of the base station used to post-process the data. Data were collected in the North American Datum of 1983 (NAD83), Universal Transverse Mercator Zone 17 North (UTM zone 17N) coordinate system.
  3. How accurate are the heights or depths?
    The vertical accuracy of the post-processed kinematic GPS data is +/- 3 cm, based on the accuracy of the base station used to post-process the data. Data were collected in the North American Vertical Datum of 1988 (NAVD88) coordinate system.
  4. Where are the gaps in the data? What is missing?
    Dataset is considered complete for the information presented, as described in the abstract.
  5. How consistent are the relationships among the observations, including topology?
    No formal logical accuracy tests were conducted.
