Tidal Anomalies for New South Wales Coast, Adjusted to AHD Datum

Manly Hydraulics Laboratory and the Australian Bureau of Meteorology provided hourly and 15-minute ocean water levels from the New South Wales coast. The data were adjusted to the Australian Height Datum (AHD) and had rainfall-related peaks removed to compile a high-quality set of tidal residuals. This collection accompanies a data descriptor paper, has a DOI, and is maintained by the Australian Ocean Data Network.

Use Cases

• Modeling storm surge and coastal flooding based on tidal anomaly time series.
• Analyzing long-term sea-level trends based on datum-adjusted water level records.
• Validating tidal prediction models based on residuals calculated with the Utide model.

Strengths

• Data is adjusted to a consistent vertical datum (Australian Height Datum).
• Rainfall-related peaks have been removed from onshore river entrance gauge records.
• Accompanies a peer-reviewed data descriptor paper and has a persistent DOI.

Limitations

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

Source

Manly Hydraulics Laboratory (MHL) and Australian Bureau of Meteorology (BOM), aggregated by Australian Ocean Data Network (AODN).

Collection Method

Coastal water levels collected from tide gauges (onshore bay, onshore river entrance, offshore open ocean), adjusted to AHD, with tidal anomalies derived using the Unified Tidal Analysis and Prediction (Utide) model.
