Clam performs 'classical' age-depth modelling for dated sediment deposits, a step prior to applying more sophisticated Bayesian techniques. The tool calibrates radiocarbon-dated depths and constructs models by repeatedly sampling dated levels to draw age-depth curves. It was created by Maarten Blaauw, with methodology detailed in a 2010 publication.
Use Cases
- Calibrating radiocarbon dates from sediment core depths based on the description.
- Constructing linear interpolation age-depth models for sediment sequences.
- Applying polynomial regression to model non-linear sedimentation rates.
- Generating spline-based age-depth curves for core analysis.
Strengths
- Methodology is documented in a peer-reviewed 2010 publication by Maarten Blaauw.
- Supports multiple model types including interpolation, regression, and splines as described.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Last update date is unknown; freshness unverified.
