Satellite-Derived Bathymetry for Ashmore Reef and Cartier Island Marine Parks (2022-2023)

Ashmore Reef and Cartier Island Marine Parks in Western Australia are covered by this bathymetric dataset. The data was derived from WorldView-3 multispectral satellite imagery using a physics-based inversion method by EOMAP Australia Pty Ltd and EOMAP GmbH & Co.KG. It was acquired in 2022-2023 as part of the Australian Government's Marine Parks Grant - Round 3.

Use Cases

• Modeling coastal erosion and sediment transport based on high-resolution bathymetry.
• Monitoring benthic habitat changes for conservation management based on the described environmental baseline.
• Supporting ecological research on shallow water ecosystems based on the georeferenced habitat maps.
• Assessing climate change impacts on marine parks based on the long-term monitoring baseline.

Strengths

• Data was derived from WorldView-3 satellite sensor, suggesting high spatial resolution.
• Covers two specific Marine Parks (Ashmore Reef and Cartier Island) in Western Australia.
• Processed using a physics-based inversion method for quantitative bathymetric information.
• Acquired as part of a formal government grant program (Marine Parks Grant - Round 3).

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 dataset is explicitly not to be used for navigational purposes.
