Celtic Deep 2 Lander: Seabed Biogeochemical Sensor Time Series

Shelf Sea Biogeochemistry - Celtic Deep 2 Lander data consists of biogeochemical sensor measurements from a seabed mooring. The Government Digital Service collected data on temperature, salinity, dissolved oxygen, chlorophyll fluorescence, and turbidity at 1 meter above the seabed using a Cefas ESM2 logger. Sensors were validated against in-situ samples and calibrated with standard materials.

Use Cases

• Modeling benthic oxygen dynamics based on dissolved oxygen and temperature time series.
• Analyzing phytoplankton biomass near the seabed using chlorophyll fluorescence data.
• Studying sediment resuspension events based on turbidity measurements.
• Investigating seasonal water column properties from concurrent salinity and temperature records.

Strengths

• Sensor data was validated against in-situ samples during deployment and recovery.
• Instruments gathered data for 5 minutes every 30 minutes, providing a regular time series.
• Fluorometers were standardized using fluorosphere beads and turbidity meters were calibrated using Stabical.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
