Data Quality and Control

Sensor performance matches the manufacturer specifications indicating the flow stream is not introducing any additional error. Sensor drift is assessed annually with calibration at CSIRO marine laboratories. Additional drift associated with any fouling of the sensors is kept in check with cross-check to standards on every 3-4 week service.

Sensor accuracy and environmental noise measured during trials in June 2008 showing sensitivity to 0.0001 degC; 0.004 psu; 0.02 Chl-a and 0.02 NTU
