Laboratory-grown foraminifera tests of the planktic species Globigerina bulloides were collected from the Norwegian Sea in summer 2022. The dataset provides element/Ca ratios (Mg/Ca, Na/Ca, Sr/Ca) for these cultured specimens and their culturing substrate, measured by Laser Ablation ICP-MS at the University of Southampton in summer 2023. Data corresponds to articles by Sykes et al. (2024 and in submission).
Use Cases
- Calibrating Mg/Ca paleothermometry proxies based on foraminifera grown at controlled low temperatures (6–13°C).
- Investigating the influence of salinity (30.4–37.8) on trace element incorporation in biogenic carbonate.
- Modeling the impact of varied carbonate chemistry (pH 7.7–8.3, [CO32-] 77-225 µmol/kg) on foraminiferal shell composition.
- Comparing elemental ratios between cultured foraminifera and their growth medium to understand partitioning.
Strengths
- Data is derived from controlled laboratory experiments with specified environmental parameters: temperature (6–13°C), salinity (30.4–37.8), and carbonate chemistry.
- Elemental ratios were measured using Laser Ablation Inductively Coupled Plasma Mass Spectrometry, a precise analytical technique.
- Includes measurements from both the cultured foraminifera and their culturing substrate, enabling comparative analysis.
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 statistical modeling.
