Beagle Marine Park Bathymetry Grids at 1-Meter Resolution

Beagle Marine Park in the Bass Strait was surveyed from 17 to 26 June 2018. The dataset comprises 11 bathymetry grids at 1-meter spatial resolution, covering a combined area of 366 square kilometers, collected via multibeam sonar by Geoscience Australia and the University of Tasmania. This baseline information supports the 10-year management plan (2013-2023) for the South-east Marine Park Network.

Use Cases

• Modeling seafloor topography and habitat complexity based on high-resolution bathymetry grids.
• Establishing environmental baselines for marine park management based on the described survey phases.
• Integrating seabed data with other survey phases (AUV imagery, BRUVs) for holistic benthic studies.

Strengths

• High-resolution 1-meter gridded data for precise seafloor analysis.
• Covers a defined area of 366 square kilometers within a marine park.
• Data collection is documented in a published 2019 post-survey report.

Limitations

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