Abalone Fishing Block 28 Habitat Maps with 50cm Resolution Acoustic Data

High-resolution 50cm bathymetry and substrate maps detail seafloor habitats off Tasmania's east coast. The Australian Ocean Data Network produced this snapshot of 2021 habitat distribution for strategic urchin control and abalone management. Data products include substrate classification, bathymetry derivatives, and vegetation likelihood from multibeam acoustic imagery.

Use Cases

• Map fine-scale spatial distribution of key abalone habitat based on multibeam acoustic imagery.
• Predict and monitor urchin barrens for invasive species management based on water column data.
• Facilitate strategic decision-making for abalone fisheries based on detailed substrate and kelp coverage maps.

Strengths

• High-resolution 50cm bathymetry and substrate data.
• Includes multiple derived data products like seabed slope, curvature, and rugosity.
• Provides a 2021 snapshot of seafloor habitat distribution for temporal comparison.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to data_gov_au, focusing only on specific Tasmanian fishing blocks.
