Geographe Marine Park Bathymetry Grid

Geoscience Australia provides a 5-meter resolution bathymetry grid for the Geographe Marine Park, part of Australia's network of 58 Commonwealth marine parks covering 3.3 million square kilometers. The dataset includes derived morphological surface classifications categorizing seafloor slope into Plains, Slopes, and Escarpments. These grids support the development of eco-narrative documents for park management under plans effective from July 2018.

Use Cases

• Marine habitat mapping based on derived seafloor slope categories (Plain, Slope, Escarpment).
• Management plan development for marine parks using collated bathymetric interpretations.
• Eco-narrative document creation integrating seafloor geomorphology, oceanography, and ecology.
• Seafloor visualization combining bathymetric data with hillshade imagery into panchromatic geotiffs.

Strengths

• Covers a defined marine park within a network spanning 3.3 million square kilometers.
• Applies a published two-part seafloor morphology classification scheme (Dove et al., 2016).
• Provides high-resolution (5m) bathymetric data compiled from Geoscience Australia's holdings.

Limitations

• Specific column names and dataset size/row counts are not provided in the source metadata.
• License information and precise authorship details are missing from the available records.
• The 'last updated' dates conflict between sources (2026-06-27 and 2026-06-04).
