Title:
UFK14RBR77750p-trm_metadata: 2014–2015 Ocean Current and Pressure Time Series Data from the Upper Florida Keys: Crocker Reef, FL
Abstract:
Three Acoustic Doppler current profilers (ADCP), a current meter and a pressure logger were deployed at Crocker Reef, a senile (dead) barrier reef located in the northern portion of the Florida Reef Tract from December 12, 2014 to January 30, 2015 to quantify flow characteristics in various sub-regions. A RBR pressure logger was deployed on the fore reef and configured to measure pressure at a rate of 2 hertz (Hz). The logger was positioned at a water depth of 14 meters, the deepest part of the fore reef) in order to obtain wave statistics measurements.

Why was the data set created?

The temperature, water depth, wave and current data from the fore reef and reef flat in Crocker Reef, FL were used to quantify the physical characteristics and forcing on the reef. This time series dataset includes raw data downloaded from a pressure meter installed at the RBR site location. The files provided in this data release were converted from the original, proprietary format to the Network Common Data Form (NetCDF) to help facilitate accessibility and distribution to the public.

  2. How were the data generated, processed, and modified?
    Date: 2017 (process 1 of 2)
    Prior to survey commencement, the RBR pressure logger was calibrated by RBR to ensure equipment-related errors would be minimal and the instrument was operating at peak efficiency. Using a self-contained underwater breathing apparatus (SCUBA), USGS staff deployed the meter at the pre-determined site, called RBR on December 09, 2014. Instrument was recording with internal data logger and power using internal batteries, it was retrieved the afternoon of January 30, 2015 to download data following instructions in the RBR manual. Using a Matlab script, the raw data were converted from a proprietary file type to NetCDF format and trimmed to include only points that correspond to times when the instrument was actually deployed on the seafloor.

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?
    Location information (point position) for this site was obtained from a Garmin GPSmap 62s handheld global positioning system (GPS) with a nominal accuracy of 3 to 5 meters (m) 95% typical (WAAS accuracy in North America).
  3. How accurate are the heights or depths?
    The vertical datum used for this dataset was the North American Vertical Datum of 1988 (NAVD88) with an estimated resolution of 0.3 m.
  4. Where are the gaps in the data? What is missing?
    This dataset is considered complete for the information presented, as described in the abstract section. Users are advised to read the rest of the metadata record carefully for additional details.
  5. How consistent are the relationships among the observations, including topology?
