High-Resolution Bathymetry Grids for Cocos (Keeling) Island with Topography

Cocos (Keeling) Island is a mid-ocean atoll located approximately 3,685km west of Darwin. This report from the Australian Ocean Data Network describes the creation of four detailed bathymetry grids for the region, integrating seabed data with island topography. The data are intended for identifying seabed processes and habitats and for modelling tsunami interactions with the island's shelf and coast.

Use Cases

• Model tsunami wave interaction and inundation based on the integrated bathymetry and topography grids.
• Identify major seabed habitats and geological processes based on high-resolution depth data.
• Analyze the shallow (1-20m) shelf morphology surrounding the atoll based on the bathymetry models.

Strengths

• Includes four distinct bathymetry grids, with some integrating island topography.
• Covers a specific, remote geographic region: the Cocos (Keeling) Island atoll.
• Methodology for data collection, quality control, and gridding is described in the report.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
