Gifford Marine Park Bathymetry Grid at 30-Meter Resolution

Gifford Marine Park's seafloor depth data is provided as a 30-meter resolution grid. Geoscience Australia compiled and processed the bathymetry from its data holdings, creating a panchromatic geotiff image combined with a hillshade. This release supports the management of Australia's national network of 58 marine parks.

Use Cases

• Classifying seafloor morphological surfaces (Plain, Slope, Escarpment) from slope values derived from the bathymetry grid.
• Generating hillshade visualizations and derived products for interpreting seafloor geomorphology within the park.
• Integrating bathymetric data with oceanographic and ecological layers to develop 'eco-narrative' documents for park management.
• Analyzing bathymetric gradients to identify shelf habitats, slopes, and abyssal plains within the marine park boundaries.

Strengths

• Bathymetry is gridded at a 30-meter resolution, providing detailed seafloor topography.
• Data contributes to the management of a national network covering 3.3 million square kilometers of Commonwealth waters.

Limitations

• The dataset is explicitly not to be used for navigational purposes, limiting its operational applications.
• Specific row counts, file sizes, and the exact temporal coverage for Gifford Park are not provided.
