An Emerging Priorities project from the NESP Marine and Coastal Hub assesses impacts of a 2025 harmful algal bloom in South Australia. The project, conducted by SARDI, Adelaide University, and Flinders University, integrates towed-camera imagery, stereo-BRUV surveys, benthic trawl data, and environmental measurements. Outputs include post-bloom benthic imagery, quantitative impact assessments, and a final technical report.
Use Cases
- Assessing changes in benthic habitat condition based on towed-camera imagery resurveys.
- Evaluating changes in fish and invertebrate community composition based on repeat stereo-BRUV surveys.
- Comparing pre- and post-bloom ecosystem states using existing baseline data.
- Supporting the development of HAB-related coastal habitat monitoring programs based on integrated survey findings.
Strengths
- Project leverages existing pre-bloom baseline data for robust before-after comparisons.
- Assessment integrates multiple survey methods: towed-camera imagery, stereo-BRUV surveys, benthic trawl data, and environmental measurements.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
