Seamounts and Raised Seabed Features of the Australian Margin (NESP MaC 2.3)

Seamounts and elevated seabed features constitute ecologically significant habitats for marine species. This dataset provides an improved inventory of these features for the area surrounding the Australian continental margin, developed by the NESP Marine and Coastal Hub Project 2.3. It integrates multiple data sources, including high-resolution bathymetry, and prioritizes features within the Australian Exclusive Economic Zone.

Use Cases

• Modeling marine biodiversity hotspots based on the location of seamounts and bathymetric highs.
• Planning marine protected areas based on the inventory of ecologically significant seabed features.
• Cross-referencing habitat models with the GEBCO 2023 global terrain model for accuracy validation.
• Prioritizing conservation efforts for unique ecosystems associated with raised seabed features.

Strengths

• Incorporates recent high-resolution bathymetry from sources like the 'Bathymetry of Australian Marine Parks (2024)' compilation.
• Prioritizes fine-scale geomorphic mapping data over broader-scale datasets when discrepancies exist.
• Includes features both inside and in the vicinity of the Australian Exclusive Economic Zone for contextual analysis.

Limitations

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