Seawater-derived aragonite samples were precipitated in vitro between September 2021 and December 2022. The dataset contains full width half maxima (FWHM) measurements of the ν1 peak from Raman spectroscopy, collected to investigate how biomolecules and calcification fluids affect aragonite structure. Data were collected and interpreted by researchers including Giacomo Gardella, Sam Presslee, and Nicola Allison from the British Geological Survey.
Use Cases
- Analyze FWHM values to correlate aragonite structural disorder with the presence or absence of specific biomolecules during precipitation.
- Model the relationship between seawater chemistry conditions and the ν1 peak FWHM as a proxy for crystal quality.
- Compare FWHM distributions across experimental batches to identify statistical outliers in biomineralization processes.
Strengths
- Data covers a defined experimental period from September 2021 to December 2022.
- Measurements focus on a specific, analytically relevant spectral feature (ν1 peak FWHM).
- Research context is clearly stated for biomineralization and calcification fluid studies.
Limitations
- Sample size and row count are unknown, limiting statistical power assessment.
- The absence of column details prevents understanding of accompanying experimental variables.
- Data is restricted to in vitro precipitated samples, not natural biogenic aragonite.
