Gifford Marine Park Bathymetry Grid At 30-Meter Resolution

Bathymetry data provides seafloor depth information for the Gifford Marine Park within Australia's Commonwealth network. The dataset includes a 30-meter resolution grid and derived morphological surface classifications based on slope. Geoscience Australia compiled and processed this data, contributing to marine park management plans effective from July 2018.

Use Cases

• Modeling seafloor habitat by classifying Morphological Surfaces (Plain, Slope, Escarpment) from bathymetric slope.
• Creating composite visualizations by combining the bathymetry grid with a hillshade image to illustrate terrain.
• Analyzing the relationship between bathymetry and ecological data within the 3.3 million square kilometre marine park network.
• Supporting marine park management plans through interpretations of seafloor geomorphology and oceanography.

Strengths

• Data is gridded at a consistent 30-meter spatial resolution.
• Derived products include classified Morphological Surfaces based on a published two-part classification scheme.
• Contributes to the management of a network of 58 marine parks covering 40% of Australia's exclusive economic zone.

Limitations

• The specific spatial extent (bounding box) and depth range for Gifford Park are not provided.
• Sample data and total file size are unavailable for preliminary assessment.
• The dataset is explicitly not for navigational purposes, limiting its operational use.
