A Nortek Aquadopp current meter was deployed on the reef flat and configured to measure three-dimensional flow velocities at the middle of the water column. Current measurements were taken at a rate of 1 hertz (Hz) for 120 seconds (s) every 10 minutes; each 120-s sampling was internally averaged to provide data at 10-minute resolution. Purpose: 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 current meter installed at the Aqua 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.

Completeness_Report: 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. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: 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). Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The vertical datum used for this dataset was the North American Vertical Datum of 1988 (NAVD88) with an estimated resolution of 0.3 m. Lineage: Process_Step: Process_Description: Prior to survey commencement, the Aquadopp was calibrated by Nortek 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 Aqua on December 10, 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 Aquadopp current meter 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.
