“…deployment up to 50 m, which makes it suitable for vertical profiling and for towed deployments to conduct spatial surveys. Gardolinski et al [27] and David et al [28,29] used this monitor, fitted with a nitrate=nitrite manifold, for submersible real-time monitoring in the North Sea and in the Tamar Estuary, respectively.…”

& The development and deployment of a portable flow injection analyzer for continuous, real-time monitoring of filterable reactive phosphorus (FRP) in the Tamar catchment is described. The optimized method can be used for the determination of FRP in freshwater systems (4-150 lg L À1 P) and is capable of sampling with high temporal resolution (up to 15 samples h À1 ). The analyzer, fitted with a pre-filter and an in-line membrane filter (0.45 lm, cellulose acetate), was used in situ (bank-side and shipboard deployment) to provide real-time FRP data and in the laboratory to determine FRP in freshwater samples. The portable FRP analyzer was reproducible (RSD < 5%; n ¼ 3) over the range 4-150 lg L À1 P and accurate, achieving good agreement with a laboratory based air-segmented continuous flow analyzer reference method for a range of freshwater samples from the Tamar catchment in SW England.
