Data Format
Brief descriptions of the format and content of the data files available in this report are presented below. Data are organized by type in the Data Access section or by station name (SH1, GS-203, GS-33, NP202, GS-36) in the Study Area and Station Description section.
Velocity Files
Quality-checked and edited velocity data are available as comma-separated values in ASCII text files (.adv) for each deployment. The following parameters are included in each file:
Station Description
- Station name
- Easting, in Universal Transverse Mercator (UTM) coordinates, North American Datum 1983 (NAD 83), Zone 17, meters (m)
- Northing, in Universal Transverse Mercator (UTM) coordinates, North American Datum 1983 (NAD 83), Zone 17, meters (m)
- Sample volume height above the top of the plant-litter layer, in centimeters (cm)
Data
- Burst #, year, month, day, hour, minute
- Velocity for each component (east, north, and up), in centimeters per second (cm/s)
- Correlation for each component (east, north, and up), in percent (%)
- Amplitude for each component (east, north, and up), in counts
- Signal-to-noise (SNR) ratio for each velocity component (east, north, and up), in dB units
- Horizontal flow speed, in centimeters per second (cm/s)
- Horizontal flow direction, in degrees clockwise from magnetic north (° CW from MN)
- Number of samples passing the automated filter
Note: Files from the 1999-2000 wet season include additional parameters of standard deviations for the east and north velocity components, as indicated in the column headings.
Conductivity and Temperature Files
Quality-checked and edited conductivity and temperature data are available as comma-separated values in ASCII text files (.ctd) for each deployment. The following parameters are included in each file:
Station Description
- Station name
- Easting, in Universal Transverse Mercator (UTM) coordinates, North American Datum 1983 (NAD 83), Zone 17, meters (m)
- Northing, in Universal Transverse Mercator (UTM) coordinates, North American Datum 1983 (NAD 83), Zone 17, meters (m)
- Sample volume height above the top of the plant-litter layer, in centimeters (cm)
Data
- Burst #, year, month, day, hour, minute
- Temperature, in degrees Celsius (°C)
- Conductivity, in Siemens per meter (S/m)
- Salinity, in parts per thousand (ppt)
- Specific conductance, in microSiemens per centimeter (µS/cm at 25 °C)
Note: Measured conductance was converted to salinity by methods documented in Sea-Bird Electronics Inc. (1999).
Temperature-Profile Files
Quality-checked and edited temperature-profile data and additional site-specific information are available in Microsoft® Excel (.xls) spreadsheet format for each station.
The following worksheets are included in each temperature-profile data file:
- Station Description - station name, easting and northing in Universal Transverse Mercator (UTM) coordinates, North American Datum 1983 (NAD 83), Zone 17, meters (m), instrumentation, and vegetation type
- Measurement Notes - parameter units, instrument specifications, and equation used to convert measured resistance to temperature
- Deployment Settings - list of deployment dates, recording intervals, and measurement locations
- Water Depths - dates, times, and depths at the site
- Data Files - temperature, in degrees Celsius (°C) at 11 locations in the water column, air, and (or) on the water surface (Data are compiled in separate spreadsheets by wet season and changes in set-up parameters)
Water-Depth Files
Approximate water depths at the flow-monitoring stations are available in Microsoft® Excel (.xls) spreadsheet format. Each file contains the following parameters:
- Date and time
- Water depth at the ADV meter or thermistor string
