Smartbuoy Observational Network: Warp 2000-2010 Marine Sensor Data

Hourly nitrate and twice-hourly phytoplankton biomass measurements from a marine SmartBuoy located at 51.5235 N, 1.024 E. The buoy, operated by the Government Digital Service, started logging in November 2000 and remains operational, with data telemetered via satellite every two hours. Supporting measurements include conductivity, temperature, suspended sediment, and light penetration.

Use Cases

• Modeling phytoplankton bloom dynamics based on chlorophyll fluorescence measurements.
• Analyzing seasonal nutrient cycles based on nitrate and silicate concentration data.
• Correlating water quality parameters based on concurrent measurements of temperature, conductivity, and suspended sediment.
• Studying long-term environmental trends based on a decade-long time series from a fixed location.

Strengths

• Provides high-frequency, in-situ measurements (hourly and twice-hourly) for key biological and chemical variables.
• Includes a long-term, continuous record from a fixed geographic location starting in November 2000.
• Data is supported by auxiliary environmental measurements (conductivity, temperature, sediment, light) to aid interpretation.

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 ML tasks.

Collection Method

In-situ measurements from a SmartBuoy platform using NAS-3X nutrient analysers, fluorometers, and an ESM2 logger, with satellite telemetry.

Time Range

November 2000 onward

Freshness

The buoy is described as still operational, but the last update date for the dataset is unknown.

Geography

Fixed location at 51.5235 N, 1.024 E (likely the Thames Estuary/Warp region).
