dc.description.abstract | Improved comparability of nutrient concentrations in seawater is required to enhance the
quality and utility of measurements reported to global databases. Significant progress
has been made over recent decades in improving the analysis and data quality for
traditional laboratory measurements of nutrients. Similar efforts are required to establish
high-quality data outputs from in situ nutrient sensors, which are rapidly becoming
integral components of ocean observing systems. This paper suggests using the good
practices routine established for laboratory reference methods to propose a harmonized
set of deployment protocols and of quality control procedures for nutrient measurements
obtained from in situ sensors. These procedures are intended to establish a framework
to standardize the technical and analytical controls carried out on the three main types
of in situ nutrient sensors currently available (wet chemical analyzers, ultraviolet optical
sensors, electrochemical sensors) for their deployments on all kinds of platform. The
routine reference controls that can be applied to the sensors are listed for each step of
sensor use: initial qualification under controlled conditions in the laboratory, preparation
of the sensor before deployment, field deployment and finally the sensor recovery. The
fundamental principles applied to the laboratory reference method are then reviewed in
terms of the calibration protocol, instrumental interferences, environmental interferences,
external controls, and method performance assessment. Data corrections (linearity,
sensitivity, drifts, interferences and outliers) are finally identified along with the concepts
and calculations for qualification for both real time and time delayed data. This paper
emphasizes the necessity of future collaborations between research groups, referenceaccredited
laboratories, and technology developers, to maintain comparability of the
concentrations reported for the various nutrient parameters measured by in situ sensors. | en_US |
