Multi-Resolution Bathymetry Mosaics for Australian Waters, Stratified by Depth Zone

A mosaicked product of all publicly available bathymetry data within the Australian Exclusive Economic Zone as of July 2024. The dataset provides full coverage through eight depth-stratified bathymetry mosaics and associated derivatives like hillshade and slope, with resolutions ranging from 10 to 210 meters. It was produced by the NESP MaC 2.3 project and aggregated by the Australian Ocean Data Network.

Use Cases

• Marine habitat modeling based on bathymetry and derived slope/aspect layers.
• Seabed morphology analysis using the multi-resolution depth mosaics for different ecosystem zones.
• Creating base maps for marine spatial planning based on the full-coverage, depth-stratified composites.
• Assessing seafloor characteristics for infrastructure planning using the systematic prioritization of high-resolution inputs.

Strengths

• Provides full spatial coverage of Australia's Exclusive Economic Zone.
• Systematic prioritization approach uses newer, high-resolution bathymetry inputs where available.
• Includes eight distinct depth zones with specified grid resolutions, from 10m for shallow zones to 210m for abyssal zones.
• Offers associated derivative products like hillshade, slope, and aspect for each mosaic.

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.
• Data may reflect geographic or source bias inherent to the aggregation of publicly available sources.
