Australian Ocean Data Network provides high-resolution acoustic mapping data for Fishing Block 23 on Tasmania's east coast. The dataset includes 50cm resolution bathymetry, substrate classification, and derivatives, capturing a snapshot of seafloor habitats and vegetation distribution for 2021. It was produced to map fine-scale habitat impacted by urchins and assist in strategic decision-making for urchin control and abalone management.
Use Cases
- Mapping fine-scale spatial distribution of key abalone habitat based on multibeam acoustic imagery.
- Predicting large urchin barrens and detecting small incipient barrens based on water column data.
- Analyzing substrate type and kelp coverage for strategic decision-making in urchin control.
- Generating seabed derivatives like slope and rugosity for habitat modeling.
- Assessing vegetation likelihood for marine vegetation distribution studies.
Strengths
- High-resolution 50cm bathymetry and substrate maps.
- Multiple data products including bathymetry derivatives and water column statistics.
- Specific temporal snapshot for 2021 distribution.
- Geographic focus on a defined fishing block (23) on Tasmania's east coast.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data is split across multiple fishing blocks; this record covers only Block 23.
