Beagle Marine Park Bathymetry Grids at 1-Meter Resolution, 2018

Eleven bathymetry grids covering 366 km² of the Beagle Marine Park in Bass Strait, derived from multibeam sonar data collected in June 2018. The data was acquired by Geoscience Australia and the University of Tasmania's Institute for Marine & Antarctic Studies as part of a National Environmental Science Program project. This Phase 1 survey provides baseline information for benthic habitats to support a 10-year marine park management plan.

Use Cases

• Modeling seafloor terrain and slope for habitat suitability based on high-resolution bathymetry grids.
• Establishing baseline maps for monitoring environmental change within the South-east Marine Park Network.
• Informing marine park management plans by characterizing benthic habitat structure.

Strengths

• High spatial resolution of 1 meter for detailed seafloor analysis.
• Covers a combined area of 366 square kilometers within a defined marine park.
• Data collection is documented in a detailed, cited post-survey report.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic and temporal bias inherent to the single survey period in 2018.
