NESP MB SS3: Coral Cover Trends in Northern Australia After 2016-2017 Heatwaves

National trends in coral species following heatwaves were quantified by taxonomic experts annotating Reef Life Survey photoquadrats. The project focuses on spatial and species-level responses to the 2016 and 2017 marine heatwave and mass bleaching events across northern Australia. Data outputs are managed by the Australian Ocean Data Network, with metadata last updated in June 2026.

Use Cases

• Modeling species-specific vulnerability to warming based on pre- and post-disturbance cover data
• Identifying candidate species for coral restoration efforts based on observed recovery patterns
• Contributing to national environmental reporting on coral reef health following major heatwaves
• Analyzing the combined impact of heatwaves and cyclones on coral community composition

Strengths

• Data is annotated by coral taxonomic experts, which likely increases taxonomic accuracy
• Focuses on a significant ecological event: the 2016 and 2017 mass bleaching and heatwave events
• Planned output includes percent cover data to the highest possible taxonomic resolution

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
