Multi-resolution Bathymetry Composite Surface for Australian Waters

A mosaicked product of all publicly available bathymetry data within the Australian Exclusive Economic Zone (EEZ) as of July 2024. It consists of 8 depth-stratified mosaics and derivatives (hillshade, slope, aspect) for ecosystem zones from 0 to over 6,000 meters, with resolutions ranging from 10 to 210 meters. The dataset was produced by the Australian Ocean Data Network using a systematic prioritization approach for input data.

Use Cases

• Marine habitat modeling based on depth-stratified ecosystem zones.
• Seabed geomorphology analysis using slope and aspect derivatives.
• Visualizing full-coverage bathymetry of Australia's marine estate via WMS endpoints.
• Prioritizing survey areas by identifying regions where foundational Digital Elevation Models were used.

Strengths

• Provides full coverage of Australia's marine estate clipped to the EEZ boundary.
• Includes 8 distinct mosaics with resolutions tailored to specific depth zones, from 10m to 210m.
• Integrates all publicly available bathymetry data as of July 2024.
• Offers associated derivative products: hillshade, slope, and aspect.

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 source bias inherent to the aggregated public data sources.
