39 coral skeletal samples from 7 genotypes of massive Porites spp. corals were analyzed. Data capture the full width half maxima (FWHM) of the ν1 aragonite peak from samples cultured under varying seawater pCO2 levels (180 to 750 µatm) and temperatures (25 and 28°C). The data were collected between August 2020 and December 2022 by researchers including Phoebe Ross and Nicola Allison to study environmental influences on aragonite lattice disorder.
Use Cases
- Model the relationship between seawater pCO2 levels and the FWHM of the ν1 aragonite peak to quantify acidification effects.
- Analyze the combined effect of seawater temperature and pCO2 on skeletal aragonite disorder measured via Raman spectroscopy.
- Compare FWHM values across the 7 coral genotypes (G1 to G7) to assess genetic variation in skeletal response to environmental stress.
Strengths
- Data includes 39 distinct coral skeletal samples.
- Experimental design covers 4 precise pCO2 levels (180, 260, 400, 750 µatm) and 2 temperature levels (25, 28°C).
- Samples originate from 7 distinct coral genotypes, enabling genotype-level analysis.
Limitations
- Sample size is limited to 39 total observations, which may constrain statistical power for complex models.
- Data is restricted to a single coral genus (Porites spp.) from controlled aquarium culture, limiting ecological generalizability.
