SmartBuoy Marine Observational Network dataset https://portal.medin.org.uk/portal/start.php?tpc=009_CEFAS1abbc9be-1014-45ac-a281-808310790c31 This ongoing data set consists of biogeochemical sensor data from the SmartBuoy moorings and related platforms which use ESM2 and ESMx data-loggers. 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.The typical SmartBuoy configuration measures temperature, salinity, dissolved oxygen, chlorophyll fluorescence, turbidity and photosynthetic active radiation (PAR) sensors.A "Licor-arm" is also often fitted providing PAR measurements additionally from 1 and 2 meters.The buoys are also typically fitted with a water sampler which collects pre-spiked bag samples for later nutrient (Nitrate and Silicate or phytoplankton analysis. The NAS-3X in-situ nutrient analyser is also used on some sites which provides nitrate concentration measurements at a higher freuency than the water samples.Data are telemetered every two hours using satellite telemetry. Seabed landers have also been fitted with ESM-2 data loggers and the data collected is featured here.The mooring consists of a 3 legged stainless steel "minilander" 1.5 meters high.The biogeochemical sensors are mounted at 1 meter above the seabed.These platforms often also include upward facing acoustic Doppler current profiler (ADCP) instruments, this data is **not** held in the SmartBuoy database however.A table of deployment locations as of July 2017 is given below: +----------------+-----------+---------+----------+-----------+-----------+----------+ |Deployment |Code |Latitude
