Planktonic Foraminifera Size and Concentration Data from the FORCIS Database

FORCIS database data and R code for a new size normalization approach for planktonic Foraminifera number concentrations. The data was collected from the global ocean at different depths over the past century. The work by Sonia Chaabane and colleagues yields multiplication factors to normalize concentrations across size fractions equal to or larger than 100 µm.

Use Cases

• Normalizing planktonic Foraminifera number concentrations across different size fractions based on the described Michaelis Menten function.
• Validating size normalization models against independent datasets based on the cross-validation script.
• Comparing new size correction schemes with historical methods like the Berger 1969 correction based on the provided analysis scripts.

Strengths

• Data sourced from the FORCIS database, a global collection of planktonic Foraminifera records.
• Includes R code for data preparation, model building, validation, and comparison with an earlier method.
• Model provides multiplication factors for normalizing number concentrations across size fractions >=100 µm.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
