Intertidal Areas of the Australian and Lord Howe Island Continental Shelves

Australian and Lord Howe Island continental shelves have their intertidal areas derived from the Australian Hydrographic Service's S57 file series. The data was aggregated and dissolved from depth area features within the 1-degree file series for the 200-meter shelf. The dataset is hosted by the Australian Ocean Data Network and was last updated in July 2026.

Use Cases

• Modeling coastal erosion and sediment transport based on derived intertidal boundaries.
• Assessing habitat extent for intertidal species based on aggregated depth area features.
• Planning marine protected areas or coastal development using shelf boundary data.
• Calibrating remote sensing models of shoreline change with authoritative hydrographic data.

Strengths

• Derived from the authoritative Australian Hydrographic Service's S57 file series.
• Covers the Australian continental shelf and the Lord Howe Island shelf up to the 200-meter depth contour.
• Data was last updated on 2026-07-10, suggesting planned maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• The description metadata is limited; actual data quality and spatial resolution require manual inspection.
