Tamar Estuary Water Level Data with Tidal Amplification Analysis, March-August 2018

Water level heights were measured every 5 minutes at five stations along a 70km stretch of the Tamar estuary in Tasmania for six months. The data includes barometric pressure, water temperature, and water level relative to the Australian Height Datum, capturing tidal amplification and asymmetry. A research project completed in 2018 by Karen Palmer used this data to calibrate a hydrodynamic model for simulating sea level rise and bathymetry change scenarios.

Use Cases

• Calibrating hydrodynamic models based on observed water level, temperature, and pressure data.
• Analyzing tidal amplification and asymmetry between ebb and flood tides in an estuary.
• Modeling the effects of sea level rise and bathymetry changes on tidal amplitude and phase.
• Studying the inverse barometer effect using paired underwater and above-ground pressure loggers.

Strengths

• High temporal resolution with measurements taken every 5 minutes.
• Spatial coverage across five stations spanning a 70km estuary length.
• Data accounts for the inverse barometer effect using paired pressure loggers.
• Six-month observation period provides data for tidal cycle analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified; last metadata update is dated 2026-07-13.
