High-Resolution Bathymetry Grids for Cocos (Keeling) Island

Four detailed bathymetry grids integrate seabed depth with island topography for the Cocos (Keeling) Island region. The Australian Ocean Data Network created these models to support seabed process identification and tsunami interaction modeling. The dataset was last updated in April 2026.

Use Cases

• Model tsunami wave interaction with the island shelf using integrated bathymetry and topography grids.
• Identify major seabed habitats and processes from high-resolution depth data around the atoll.
• Analyze the shallow (1-20 m) shelf morphology from the compiled bathymetry models.
• Integrate multibeam, singlebeam, and satellite-derived data sources for a unified seabed depth model.

Strengths

• Includes four distinct bathymetry grids providing multiple data products.
• Integrates bathymetry with island topography for a continuous land-sea model.
• Compiles data from multiple sources including multibeam, singlebeam, and satellite-derived surveys.

Limitations

• Primary data format is PDF report, limiting direct machine-readability of the underlying grids.
• Explicitly not for navigational purposes, indicating potential accuracy limitations for safety-critical applications.
• Specific spatial resolution, grid cell size, and vertical accuracy metrics are not provided in the description.
