The Celtic Deep 2 SmartBuoy is located at 51.1382 N, 6.5618 W. It provides hourly and daily measurements of nitrate, silicate, chlorophyll fluorescence, conductivity, temperature, suspended sediment, and light penetration, telemetered every two hours via satellite. The buoy started logging in July 2012 and is still operational.
Use Cases
- Model phytoplankton biomass dynamics based on chlorophyll fluorescence measurements.
- Analyze nutrient cycling in coastal waters based on nitrate and silicate concentration data.
- Study sediment transport and light attenuation based on suspended sediment and light penetration readings.
- Monitor long-term water quality trends based on conductivity and temperature time series.
Strengths
- Provides high-frequency, in-situ measurements with hourly nitrate and twice-hourly chlorophyll data.
- Offers multi-instrument data integration from nutrient analyzers, fluorometers, and environmental loggers.
- Features real-time satellite telemetry with data transmitted every two hours.
- Has a long operational time series starting in July 2012.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to a single buoy location.
