High-Resolution Bathymetry Grids for Cocos (Keeling) Island

Cocos (Keeling) Island, located 3,685km west of Darwin, is a mid-ocean atoll. This dataset contains four new high-resolution bathymetry grids created by the Australian Ocean Data Network, integrating seabed depth with island topography. The data supports the identification of seabed processes and habitats, as well as tsunami modelling for the island's shelf and coast.

Use Cases

• Model tsunami wave interaction with the island's shelf based on integrated bathymetry and topography data.
• Identify major seabed habitats and processes around the atoll using detailed bathymetry grids.
• Analyze the morphology of the shallow (1-20m) shelf surrounding Cocos (Keeling) Island.

Strengths

• Includes four distinct bathymetry grids, one of which integrates bathymetry with the island's topography.
• Covers the Cocos (Keeling) Island region, a specific atoll located 3,685km west of Darwin.
• Report describes methodology for data collection, quality control, and gridding.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is explicitly not to be used for navigational purposes.
