Collected Water Quality Parameters

Water quality data are collected from stations within or adjacent to an Aquatic Preserve and reported at 30- or 15-minute intervals.

Parameters and Units

• Temp:  Water temperature is measured in degrees Celsius (C).
• SpCond:  Specific conductivity is measured in milli-Siemens per centimeter (mS/cm).
• Sal:  Salinity is measured in either parts per thousand (ppt) or practical salinity units (psu) based on sensor.
• DO_pct:  Dissolved oxygen is measured in percent saturation (%).
• DO_mgl:  Dissolved oxygen concentration is measured in milligrams per Liter (mg/L).
• Depth:  Sonde depth is measured in meters (m).
• pH:  pH is measured in standard units.
• Turb:  Turbidity is measured in either nephelometric turbidity or formazin nephelometric units (NTU/FNU) based on sensor and are considered to be equivalent for program purposes.

Additional Dataset Column Headers

• F_Record:  Flag column pertaining to all data parameters, may contain QA/QC codes which are defined in the metadata.
• F_Parameter:  Flag column pertaining to the given parameter, may contain QA/QC flags or codes which are defined in the metadata.
• Historical:  Column pertaining to which stage of QA/QC has been completed. A “0” indicates tertiary QA/QC has not been completed; a “1” indicates tertiary QA/QC has been completed and the data is considered authenticated.
• ProvisionalPlus:  Column pertaining to which stage of QA/QC has been completed. A “0” indicates that primary QA/QC has been completed; a “1” indicates that secondary QA/QC has been completed.
