Warp (TH1) NMMP SmartBuoy, 51 31'.5N - 001 01'.9E, 30/11/2000 -
These deployments form part of the National Marine Monitoring Programme (NMMP) funded by the UK Government's Department for Environment, Food and Rural Affairs (Defra)
A SmartBuoy has been deployed at a site in the outer Thames estuary in approximately 15 m water depth to observe the dynamics of plant nutrients and the growth of phytoplankton.
Measurements of plant nutrient concentrations are derived from two SmartBuoy instruments. Hourly measurements of nitrate concentration are made by the NAS2E in situ nutrient analyser, while lower frequency (daily) measurements of nitrate and silicate concentration are derived from laboratory analysis of water samples collected and preserved by the AquaMonitor.
Phytoplankton concentration (biomass) is measured four times per hour using a fluorometer measuring chlorophyll fluorescence.
To aid interpretation of these data, SmartBuoy also takes measurements of conductivity, temperature, suspended sediment concentration, light penetration and oxygen levels.
