Gabbard NMMP SmartBuoy, 52 00'.0N 002 20'.0E, 11/12/2000 - 29/8/2002

These deployments formed part of the National Marine Monitoring Programme (NMMP) funded by the UK Government's Department for Environment, Food and Rural Affairs (Defra).

A SmartBuoy was deployed at a site in the southern North Sea in approximately 45 m water depth to observe the dynamics of plant nutrients and the growth of phytoplankton.

SmartBuoy on deckMeasurements of plant nutrient concentrations were derived from two SmartBuoy instruments. Hourly measurements of nitrate concentration were made by the NAS2E in situ nutrient analyser, while lower frequency (daily) measurements of nitrate and silicate concentration were derived from laboratory analysis of water samples collected and preserved by the AquaMonitor.

Phytoplankton concentration (biomass) was measured 4 times per hour using a fluorometer measuring chlorophyll fluorescence.

To aid interpretation of these data, SmartBuoy also took measurements of conductivity, temperature, suspended sediment concentration and light penetration.
