Geographe Marine Park Seafloor Bathymetry and Morphology Grid

A 5-meter resolution bathymetric grid and derived morphological surface classification for the Geographe Marine Park in Australian Commonwealth waters. The dataset was compiled by Geoscience Australia from its bathymetry holdings and processed using a two-part seafloor classification scheme. It supports management plans established in July 2018 and was updated in April 2026.

Use Cases

• Classify seafloor morphology into Plain (<2°), Slope (2-10°), or Escarpment (>10°) categories using slope data derived from the bathymetry grid.
• Analyze the relationship between bathymetric depth features and ecological parameters for marine park management.
• Generate hillshade visualizations by combining the bathymetric data grid with illumination models for geomorphological interpretation.
• Model sediment transport or current flows using the high-resolution 5m bathymetry grid as a base layer.

Strengths

• High-resolution 5-meter grid cell size for detailed seafloor analysis.
• Data supports management for a network of 58 marine parks covering 3.3 million square kilometers.

Limitations

• Specific row/column counts and total geographic area for Geographe Park are unknown.
• Dataset is not intended for navigational purposes, limiting certain applications.
• Relies on compiled existing sonar data; resolution may vary based on original vessel systems.
