Ashmore Reef and Cartier Island Marine Parks Bathymetry

Ashmore Reef and Cartier Island Marine Parks in Western Australia are mapped via high-resolution satellite-derived bathymetry. The data was acquired in 2022-2023 using multispectral imagery from the WorldView-3 sensor and processed with a physics-based inversion method. It provides a digital baseline for environmental monitoring, ecological research, and assessing climate change impacts in shallow water zones.

Use Cases

• Ecological research and habitat modeling based on high-resolution bathymetric and benthic data.
• Long-term environmental monitoring and management of marine protected areas.
• Assessing climate change impacts on shallow reef systems.
• Supporting environmental modeling and conservation planning for the marine parks.

Strengths

• Data derived from high-resolution multispectral satellite imagery (WorldView-3 sensor).
• Provides essential environmental baseline information for long-term monitoring, as stated in the description.
• Processed using a quantitative physics-based inversion method.

Limitations

• Dataset is explicitly not to be used for navigational purposes.
• Specific column names, row counts, file sizes, and license details are not provided in the available metadata.
• The listed 'last updated' date of 2026-04-20 appears to be a future date, indicating potential metadata freshness issues.
