The Great Barrier Reef experienced unprecedented coral bleaching from 2018 to 2020. This dataset from the Australian Ocean Data Network contains genomic and environmental data to assess genetic diversity loss, adaptation signatures, and heat-tolerant symbiont prevalence in three coral species. The project aims to identify stress-tolerant coral populations for reef protection and restoration.
Use Cases
- Identify genetic markers associated with bleaching tolerance based on high-throughput genomic sequence variance analysis.
- Correlate host genetic variants and symbiont communities with ambient environmental and recent bleaching conditions.
- Map the distribution of stress-tolerant coral genes and symbionts for spatial resilience management.
- Assess the prevalence of heat-tolerant Symbiodinium photo-symbionts within surviving coral populations.
Strengths
- Focuses on a specific, critical time period of unprecedented bleaching from 2018 to 2020.
- Addresses four distinct research questions on genetic diversity, adaptation, and symbiont prevalence.
- Data is associated with the Australian Institute of Marine Science (AIMS) via the NESP TWQ project.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and dataset scale are unknown, which may limit suitability assessment.
- File formats listed are PNG and HTML, suggesting the primary data may be reports or figures rather than raw structured data.
