Coral Larval Survival on Artificial Devices, Great Barrier Reef 2018-2019

The Great Barrier Reef is the location for this dataset from a year-long field experiment tracking the survival of Acropora tenuis coral recruits on two types of artificial settlement devices. The Australian Ocean Data Network published data collected from November 2018 to December 2019, with survival assessed via in situ images taken at multiple time points up to 376 days post-settlement.

Use Cases

• Modeling coral recruit survival over time based on the tracked survival assessments.
• Comparing the effectiveness of lattice-grid versus grooved-tile settlement devices based on the experimental design.
• Analyzing the impact of biofilm and crustose coralline algae conditioning on larval settlement based on the described methodology.
• Studying spatial survival patterns based on the imaging of upper- and under-sides of each deployed device.

Strengths

• Temporal coverage includes a year-long field deployment with survival tracked at 41, 95, 185, 246, 311, and 376 days post-settlement.
• Experimental design includes two distinct device types (lattice-grids and grooved-tiles) and three replicate racks.
• Data collection method involves in situ imaging on SCUBA, providing a direct observational record.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; last updated metadata shows a future date (2026-06-23).
