High-Resolution Bathymetry Grids for Cocos (Keeling) Island

Four new bathymetry grids integrate bathymetry with the island's topography for the Cocos (Keeling) Island region. Geoscience Australia Data created this report describing data collection, quality control, and gridding methodologies. The data are intended to help identify seabed processes and habitats and to enable tsunami modeling.

Use Cases

• Model tsunami wave interaction with the island shelf based on the described bathymetry and topography integration.
• Identify major seabed habitats and processes around the atoll based on the high-resolution bathymetry data.
• Analyze the morphology of a mid-ocean coral reef atoll using the detailed bathymetry grids.

Strengths

• Includes four distinct bathymetry grids, integrating bathymetry with island topography.
• Covers a very shallow shelf area with depths ranging from 1 to 20 meters.
• Report details methodology for data collection, quality control, and gridding.

Limitations

• Dataset is not to be used for navigational purposes, limiting its application scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and data scale are unknown, which may limit suitability assessment.
