The River Sem at Prior's Farm (manipulated site for the Hants Avon DTC; paired with CCAS) monitoring site (PFAS) had a suite of instruments installed, including a 6600 series multi-parameter sonde for the measurement of Dissolved Oxygen (DO) and temperature; an Analite NEP395 for the measurement of turbidity; a Casella CEL standard 0.2mm tipping bucket gauge for the measurement of rainfall. A CNS type submersible pressure transducer was used to measure stage height and a mainstream doppler velocity transmitter was used to measure flow velocity. Stage height and flow velocity was imputed into MACE Flow Pro to estimate flow discharge at 15-minute resolution. All instruments were continuously monitored remotely and downloaded data were stored on a CR200 data logger. An ISCO 3370 sampler was used to collect daily water samples from the river for further analysis in the laboratory. All N species and P fractions were analysed on a Skalar San++ continuous flow analyser. NPOC was measured by catalytic oxidation on a Shimadzu TOC analyser.
