    dct:description """This data set consists of biogeochemical sensor data from SmartBuoy moorings 
(Mills et al, 2005). SmartBuoys consist of a 4 meter tall stainless steel 
frame with a fibreglass torroid for buoyancy. Instruments are attached at a 
nominal 1 meter depth to the frame. In-air sensors are mounted to the top of 
the torroid. The buoys feature a satellite telemetry system providing near 
real-time telemetry. Temperature, salinity, dissolved oxygen, chlorophyll, 
fluorescence, turbidity and photosynthetic active radiation (PAR) sensors were 
fitted to a Cefas ESM2 data logger. These instruments gathered data for 5 
minutes every 30 minutes. Sensors were validated against in-situ samples 
during deployment and recovery. The buoy was also fitted with a water sampler 
which took periodic samples into pre-spiked (HgCl2) bags for later nutrient 
analysis. The in-situ salinity and nutrients samples are quality controlled 
via the Quality Assurance for Marine Environmental Measurements (QUASIMEME) 
scheme.

PAR sensors were calibrated against a standard lamp.Fluorometers were 
standardised using fluorosphere beads.Turbidity meters were calibrated using 
Stabical (Hach, US).

This mooring was also fitted with a thermistor string (multiple temperature 
sensors at various depth), this data is held by BODC.""" ;
