42,000 coral colonies were surveyed between March 2010 and September 2012 to quantify bleaching impacts. The dataset likely contains health metrics for coral taxa like Pocillopora, Stylophora, Porites, and Montipora, collected by researchers from the Australian Ocean Data Network. Surveys documented bleaching severity, mortality, and benthic community shifts following successive marine heatwaves.
Use Cases
- Modeling coral bleaching severity based on thermal anomaly events mentioned in the description
- Analyzing taxonomic resilience differences among Pocillopora, Stylophora, Porites, and Montipora species
- Studying benthic community composition shifts from coral-dominated to macroalgae-dominated assemblages
- Assessing recovery timelines of coral colonies based on pigmentation and colour return data
Strengths
- 42,000 coral colonies provide a substantial sample for analysis
- Data spans a critical period from March 2010 to September 2012, covering successive bleaching events
- Specific bleaching percentages are documented, ranging from 99% at shallow sites to 17% at deeper sites
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
