Recruit survival and growth under different light intensities and light spectra RRAP CAD 1

A 12-week experimental dataset from the Australian Ocean Data Network, last updated 2026-06-27. It investigates the effects of two light spectra (blue and full) and four light intensities (5 to 160 μmol m⁻² s⁻¹) on coral spat survival and growth when co-occurring with algal communities. Survival was tracked by weekly counts, and growth was measured by analyzing the area of individual recruits in photographs taken over the study period.

Use Cases

• Modeling coral recruit survival probability based on light intensity and spectrum.
• Analyzing growth rate trajectories of coral spat from weekly photographic area measurements.
• Studying competitive interactions between coral recruits and algal communities under controlled light conditions.
• Training predictive models for coral aquaculture outcomes using environmental light parameters.

Strengths

• Experimental design includes two controlled light spectra and four precise intensity levels (5 to 160 μmol m⁻² s⁻¹).
• Longitudinal tracking over 12 weeks with weekly data points for temporal analysis.
• Includes both quantitative survival counts and image-based growth area measurements.

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 ML.
• Data may reflect experimental bias inherent to the specific laboratory or field setup.
