Coral Larval Settlement Data Under Deoxygenation Treatments

Research from the Smithsonian Institution tested the impacts of deoxygenation on brooded larvae of Porites astreoides and broadcast-spawned larvae of Diploria labyrinthiformis. The dataset contains raw settlement counts after 72-hour assays under ambient, mild, and severe oxygen treatments. The data supports a 2026 manuscript submitted to the journal Coral Reefs.

Use Cases

• Analyze coral settlement rates based on species type (Porites astreoides vs. Diploria labyrinthiformis) mentioned in the description
• Model the effect of different oxygen concentrations (ambient, mild, severe deoxygenation) on larval settlement
• Compare early life stage resilience to deoxygenation between brooded and broadcast-spawned coral species
• Validate experimental findings on species-specific life history responses to oxygen depletion

Strengths

• Data is directly linked to a peer-reviewed manuscript submitted to Coral Reefs.
• Experimental conditions (oxygen concentrations of 6.0, 3.5, and 1.5 mg L⁻¹) are explicitly defined.
• The dataset is small (3.9 KB) and openly licensed (CC-BY-4.0) for easy access and reuse.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small in scale (3.9 KB), representing a single, focused experiment.
