 USGS TM1-D5 - Optical Techniques for the Determination of Nitrate in Environmental Waters: Guidelines for Instrument Selection, Operation, Deployment, Maintenance, Quality Assurance, and Data Reporting
Brief Method Summary
 A key consideration in the deployment of sensors is the identification of a stable, secure location representative of the water body of interest. Details on site selection and instrument deployment are provided in Wagner and others (2006), and those guidelines generally apply to the use of UV nitrate sensors. There are, however, some features unique to these instruments that warrant further attention.
Scope and Application
 This section of USGS TM1-D5 covers deployment of optical nitrate sensors in the environment and sections inlude:
  • Safety
  • Physical Infrastructure
  • Sensor Mounting
  • Anti-Fouling Measures
  • Dataloggers and Controllers
  • Power and Communication
Applicable Concentration Range
Interferences
 Pipes and cages constructed to protect sensors can create depositional environments that can affect the data quality or bury the sensors.
