Eagle Nest Canyon Tree Ring Chronology from 299 to -40 BP

Tree ring width measurements from Ponderosa Pine (PIPO) trees in Eagle Nest Canyon, South Dakota, provide a climate proxy record. The chronology spans 339 years, from 299 to -40 calendar years before present. This archived study was contributed by researcher Meko and is maintained by NOAA's World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree-ring width time-series.
• Calibrate radiocarbon dating or other chronological models using the precisely dated tree-ring sequence.
• Study the growth response of Ponderosa Pine (PIPO) to environmental stressors over a multi-century period.

Strengths

• Chronology spans 339 years, providing a multi-century climate record.
• Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.

Limitations

• The dataset is temporally stale, with a last update recorded in 1990.
• Specific sample depth (number of tree cores) and measurement statistics are unknown from the provided metadata.
• Geographic coverage is limited to a single canyon site in South Dakota.
