Shelf Sea Biogeochemistry: Celtic Deep 2 SmartBuoy Sensor Data

Shelf Sea Biogeochemistry - Celtic Deep 2 SmartBuoy data consists of biogeochemical sensor measurements from a moored SmartBuoy. The buoy, first deployed in 2009 and maintained from 2014 under the SSB programme, collected near real-time data on temperature, salinity, dissolved oxygen, chlorophyll fluorescence, turbidity, and photosynthetic active radiation. The programme was co-funded by the UK's Natural Environment Research Council and the Department for Environment, Food and Rural Affairs.

Use Cases

• Modeling primary production cycles based on chlorophyll fluorescence and PAR sensor data.
• Analyzing water column structure and mixing based on temperature and salinity time-series.
• Studying dissolved oxygen dynamics and potential hypoxia events in coastal waters.
• Calibrating satellite-derived ocean color products using in-situ turbidity and chlorophyll measurements.
• Investigating the coupling between physical and biogeochemical processes from co-located sensor streams.

Strengths

• Sensor data is validated against in-situ samples during deployment and recovery.
• Quality control for salinity and nutrients follows the QUASIMEME assurance scheme.
• Instruments were calibrated using standard methods: PAR against a lamp, fluorometers with beads, turbidity with Stabical.
• Data was transmitted via satellite telemetry, providing near real-time capability.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• The dataset represents a snapshot; the full thermistor string data is held separately by BODC.
