Thecosome pteropods Limacina helicina were cultured under controlled pH conditions corresponding to pCO2 levels of 350 and 760 μatm. Calcification was estimated using fluorochrome staining and the radioisotope 45Ca, revealing a 28% decrease at the pH value expected for 2100. The dataset originates from experiments conducted in 2009 by the organization SCIOPS.
Use Cases
- Modeling future pteropod population decline based on the observed 28% calcification decrease.
- Analyzing the sensitivity of aragonitic shell organisms to anthropogenic CO2 emissions.
- Studying the cascading effects on polar food webs based on pteropod dependency as a food resource.
- Calibrating carbonate chemistry models using controlled pH and pCO2 experimental data.
Strengths
- Experimental data from controlled pH conditions corresponding to specific pCO2 levels (350 and 760 μatm).
- Calcification measured using two distinct methods: fluorochrome staining and the radioisotope 45Ca.
- Results quantify a specific 28% decrease in calcification at a future pH scenario.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect temporal bias inherent to a single-year (2009) experiment.
