Beagle Marine Park Bathymetry Grids at 1-Meter Resolution

Eleven bathymetry grids derived from multibeam sonar data collected in the Beagle Marine Park (Bass Strait) during June 2018. The data covers a combined area of 366 square kilometers at a 1-meter spatial resolution. Geoscience Australia and the University of Tasmania's Institute for Marine & Antarctic Studies collected this data as part of a collaborative project funded by the National Environmental Science Program.

Use Cases

• Modeling benthic habitat distribution based on high-resolution seabed topography.
• Supporting environmental monitoring plans for marine park networks based on the baseline survey.
• Analyzing seabed morphology for geological studies using gridded bathymetry data.

Strengths

• High-resolution 1-meter gridded data for detailed spatial analysis.
• Covers a defined area of 366 square kilometers within a marine protected area.
• Data collection is documented in a published post-survey report, providing methodological context.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
