Four data files from a 20-day experiment investigating photophysiological responses of two coral species, Acropora millepora and Pachyseris speciosa, to constant and variable daily light integrals. The experiment was conducted at the Australian Institute of Marine Science's National Sea Simulator in July 2016 using corals collected from Davies Reef on the Great Barrier Reef. Measurements include fluorescence, chlorophyll a and carotenoid concentrations, and respirometry.
Use Cases
- Modeling coral photophysiological acclimation based on fluorescence measurements of quantum yield and non-photochemical quenching.
- Comparing pigment concentration responses, such as chlorophyll a and carotenoids, between high, low, and variable light treatments.
- Analyzing the relationship between daily light integrals and physiological stress indicators like photoinhibition and light limitation.
- Studying species-specific differences in light adaptation between Acropora millepora and Pachyseris speciosa.
Strengths
- Data originates from a controlled 20-day experiment at the National Sea Simulator, a specialized facility.
- Includes four distinct measurement types: fluorescence, pigment analysis, and respirometry, providing a multi-faceted view of coral physiology.
- Experimental design compares two coral species under four specific light treatments (e.g., 32 and 6 mol photons m-2 d-1).
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 and temporal bias inherent to a single reef collection in July 2016.
