Stable oxygen isotope data (δ18O-PO4) measured on the HCl-extractable phosphorus fraction from a 1 cm-resolution sediment core. The British Geological Survey established the core chronology using 210Pb activity analysis and 8 age-depth tie points from a parallel core. This dataset provides a geochemical record from the Rutland Water Nature Reserve in the UK.
Use Cases
- Reconstructing historical phosphorus sources and cycling based on δ18O-PO4 isotope signatures.
- Developing chronological models for sediment cores based on the described 210Pb dating and tie-point method.
- Analyzing paleoenvironmental changes in lake ecosystems using high-resolution (1 cm layer) geochemical data.
- Calibrating or validating other paleolimnological proxies using the established core chronology.
Strengths
- Data resolution is high, with measurements taken from each 1 cm layer of the sediment core.
- Chronology is established using a specific method: 210Pb activity analysis and correlation with a parallel core using 8 age-depth tie points.
- Sample provenance is clear, originating from a specific sediment core (LG3A) at the Rutland Water Nature Reserve.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for specific modeling tasks.
- Data may reflect geographic bias inherent to a single site in the UK.
