Cocos (Keeling) Island Bathymetry Grids with Integrated Topography

Cocos (Keeling) Island, located 3,685km west of Darwin, is a mid-ocean atoll surrounded by a shallow shelf. The Australian Ocean Data Network created four high-resolution bathymetry grids for this region, integrating bathymetry with island topography. These grids are intended for seabed habitat identification and tsunami modeling, but are not for navigational use.

Use Cases

• Identify major seabed habitats based on detailed bathymetry data.
• Model tsunami wave interactions with the island's shelf and coast.
• Analyze seabed processes using integrated bathymetry and topography grids.
• Study coral reef atoll morphology from high-resolution depth models.

Strengths

• Includes four distinct bathymetry grids.
• Integrates bathymetry data with the island's topography.
• Describes methodology for data collection, quality control, and gridding.
• Focuses on a specific geographic region: Cocos (Keeling) Island.

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.
• Row count is unknown, which may limit suitability assessment.
