Laboratory culture experiments with the calcitic foraminifer Operculina ammonoides from the Gulf of Eilat, Israel. The dataset contains results from two experiments measuring elemental ratios in shells and seawater under controlled temperature, salinity, and calcium conditions. Data was published by Hauzer et al., 2018, and archived by NOAA NCEI with experiments conducted between 2015-04-29 and 2017-05-08.
Use Cases
- Model the relationship between seawater temperature and foraminiferal Mg/Ca or Sr/Ca ratios for paleothermometry applications.
- Analyze the effect of variable salinity (32.9 to 43.0 PSU) on shell Na/Ca and Li/Ca ratios to calibrate salinity proxies.
- Investigate the impact of calcium concentration (10.7 to 18.0 mmol/kg) on elemental incorporation into foraminiferal calcite.
- Correlate experimental growth measurements from alkalinity depletion with shell chemistry data to study calcification efficiency.
- Validate ICP-OES and ICP-MS measurements of seawater chemistry against controlled experimental conditions.
Strengths
- Data from two distinct, controlled laboratory experiments with specific temperature (22, 25, 28 °C) and salinity (32.9 to 43.0 PSU) treatments.
- Includes multiple measured geochemical proxies: Na/Ca, Mg/Ca, Li/Ca, and Sr/Ca in both shells and seawater.
- Peer-reviewed and published in a scientific journal (EPSL, 497, pp.80-91).
Limitations
- Sample size (number of foraminifera specimens or experimental replicates) is not specified.
- Geographic scope is limited to a single species (Operculina ammonoides) from one location (Gulf of Eilat).
- Data is from a specific time-bound experimental period ending in 2017.
