Seafloor Depth Mapping for Bremer Marine Park

100-meter resolution bathymetry data reveals the complex submarine canyon systems within Australia's Bremer Marine Park. This compilation of multibeam sonar data, gridded for analysis, was produced by Geoscience Australia with support from the National Environmental Science Program. The dataset was last updated in April 2026.

Use Cases

• Modeling benthic habitats using the 100-meter gridded bathymetry values.
• Analyzing the geomorphology of Bremer Canyon and adjacent canyons from the depth data.
• Supporting marine park management plans with foundational seafloor terrain information.
• Integrating bathymetric layers with other environmental data for ecosystem assessments.

Strengths

• Data is gridded to a consistent 100-meter spatial resolution.
• Covers the Bremer Marine Park area, which includes the distinctive Bremer Canyon system.
• Compiled by Geoscience Australia, a national geoscientific agency.

Limitations

• Specific row/column counts and total file size are not provided.
• The dataset is a compilation of existing data, which may introduce inconsistencies in source quality or vintage.
• Not suitable for navigational purposes, indicating it is not the most current charting data.
