B4+ Mini Buoy: Hydrodynamic Sensor Calibration Data

Acceleration and water velocity data from seven low-cost, open-source bottom-mounted float sensors called 'Mini Buoys'. The dataset, provided by the Environmental Information Data Centre, includes measurements for calibrating methods to infer inundation duration, current velocity, and wave orbital velocity from acceleration data. It contains data from three buoy designs and commercial reference sensors.

Use Cases

• Calibrating acceleration-to-velocity models based on the drag-tilt principle described in the dataset.
• Comparing hydrodynamic inference methods using linear wave theory versus direct velocity measurements.
• Evaluating the effect of sensor weight and tether length on sensitivity to wave and current detection.
• Building calibration curves for inferring hydrodynamics from acceleration data gathered by bottom-mounted floats.

Strengths

• Includes data from seven distinct sensor units, allowing for replication analysis.
• Provides calibration data for three different 'Mini Buoy' designs: 'B4', 'B4+', and 'Pendant'.
• Contains reference data from a range of commercially-available sensors for validation.

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 or temporal bias inherent to the pilot study.
