British Geological Survey data contains strontium/calcium, magnesium/calcium, lithium/calcium, and boron/calcium ratios for 107 aragonite samples precipitated in vitro. Samples were precipitated using a pH stat titrator with the constant composition technique between August 2020 and April 2022, with measured seawater pH and dissolved inorganic carbon used to estimate aragonite saturation state.
Use Cases
- Model the relationship between seawater aragonite saturation state (Ω) and measured strontium/calcium ratios across 107 precipitation experiments.
- Analyze how variations in estimated seawater [B(OH)4-] correlate with boron/calcium ratios in the precipitated aragonite solid.
- Investigate the impact of measured seawater pH on magnesium/calcium and lithium/calcium ratios in synthetic aragonite.
- Estimate aragonite precipitation rates from titrant dosing data and examine their association with trace element incorporation.
Strengths
- Contains 107 distinct aragonite samples precipitated under controlled laboratory conditions.
- Includes multiple measured and derived seawater chemistry variables: pH, DIC, [Sr], [Mg], [Li], [B], [Ca], and estimated [B(OH)4-].
- Data collection spans from August 2020 to April 2022 using the standardized constant composition technique.
Limitations
- Sample size is limited to 107 in vitro experiments, which may restrict statistical power for complex multivariate analysis.
- Data is synthetic, precipitated from seawater in a lab, and may not fully replicate natural biogenic aragonite formation processes.
