YC2 Core: Holocene Lake Sediment Isotope and Geochemistry Data from Mexico

British Geological Survey data from a 2.95-meter-long lake-sediment core (YC2) from Yaal Chac, Mexico. The dataset contains an interannual to sub-centennial resolution record of carbonate oxygen and carbon isotopes, bulk sediment geochemistry, and sedimentology. Data were published in Metcalfe et al (2022) Quaternary Science Reviews and dated using radiocarbon and short-lived radio-isotopes.

Use Cases

• Reconstructing past climate and environmental changes based on stable isotope records.
• Analyzing sediment composition and depositional history based on bulk sediment geochemistry.
• Calibrating and validating paleoclimate models based on high-resolution, dated sediment sequences.

Strengths

• Core provides a 2.95-meter-long continuous sediment record.
• Data offers interannual to sub-centennial temporal resolution.
• Chronology is established using a combination of radiocarbon and short-lived radio-isotope dating.

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 geographic bias inherent to a single lake core from Mexico.
