Effects of chronic low carbonate saturation levels on the distribution, growth and skeleta

Corals were found growing abundantly in waters 20 to 30% under-saturated with carbonate, challenging predictions about ocean acidification impacts. This dataset examines the distribution, growth, and skeletal characteristics of scleractinian and gorgonian corals along a natural deep-sea carbonate gradient. The research was conducted by Parks Australia on seamounts off southwestern Australia and was last updated in July 2026.

Use Cases

• Modeling coral resilience thresholds based on observed growth in under-saturated waters mentioned in the description
• Analyzing skeletal composition anomalies in deep-sea anthozoans based on the described carbonate gradient
• Studying the dissolution of high-magnesium calcite gorgonian skeletons versus the preservation of scleractinian skeletons below the aragonite saturation horizon
• Assessing the potential role of ferromanganese deposition in deep-sea skeletal preservation as suggested in the description

Strengths

• Includes observations from a natural deep-sea carbonate concentration gradient, providing a realistic environmental context
• Examines multiple coral taxa (scleractinians and gorgonians) and skeletal characteristics as described
• Data record is provided by Parks Australia, an authoritative government organization for marine parks

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to the specific seamounts of SW Australia studied
