Description
Eight bathymetry mosaics and derivatives provide full coverage of the Australian Exclusive Economic Zone, stratified by Parks Australia Management Effectiveness Ecosystem Component depth zones. The mosaics were created using a systematic prioritization of all publicly available bathymetry data as of July 2024, including multibeam, singlebeam, satellite, and seismic sources. Data is available as bathymetry, hillshade, slope, and aspect composites, with resolutions ranging from 10 meters in shallow zones to 210 meters in the deepest zones.
Use Cases
Modeling seabed habitats based on depth, slope, and aspect derivatives.
Creating high-resolution marine base maps for the Australian EEZ using the provided WMS endpoints.
Analyzing seafloor geomorphology across different depth zones from 0 to over 6,000 meters.
Supporting marine conservation planning for the eight defined ecosystem depth zones.
Strengths
Full spatial coverage of the Australian Exclusive Economic Zone.
Depth-stratified mosaics with eight specific zones, each with a defined grid resolution (e.g., 10m for 0-200m, 210m for >4000m).
Integrates multiple data sources (multibeam, singlebeam, satellite, seismic) with a systematic prioritization approach.
Includes associated derivative products: hillshade, slope, and aspect composites.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count and total file size are unknown, which may limit suitability assessment for large-scale processing.
Data may reflect geographic and source bias inherent to the aggregated public bathymetry sources.

Collection Method
Mosaicked product of all publicly available bathymetry data within the Australian EEZ, guided by the AusSeabed Australian Multibeam Guidelines (2020).
