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

Australian Ocean Data Network hosts data from a year-long field experiment examining the survival of Acropora tenuis coral spat on artificial settlement devices. The study, conducted from November 2018 to December 2019, tracked recruit survival on lattice-grid and grooved-tile devices deployed at Backnumbers Reef on the Great Barrier Reef. Survival was 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 data from multiple time points.
• Comparing the effectiveness of different artificial settlement device designs (lattice-grids vs. grooved-tiles) for coral aquaculture.
• Analyzing the influence of microhabitat features on post-settlement survival as suggested by the experimental design.

Strengths

• Longitudinal data with survival tracked at 6 specific time points over 376 days.
• Experimental design includes two distinct device types (lattice-grids and grooved-tiles) for comparison.
• Field deployment was conducted on a specific, named reef (Backnumbers Reef) on the Great Barrier Reef.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic bias inherent to data_gov_au, focusing on a single reef system.
