Argentine Tree Ring Chronology From 410 to -24 BP

NOAA/WDS Paleoclimatology archives a tree-ring chronology from the Estancia Teresa site in Chubut, Argentina. The data covers a period from 410 to -24 calendar years before present (BP), representing over 430 years of proxy climate records. This dataset is maintained by the NOAA National Centers for Environmental Information under its World Data Service.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a proxy.
• Calibrate radiocarbon dating curves by correlating the dated tree-ring series with other chronologies.
• Analyze climate periodicity and extreme events over the 434-year span recorded in the ring-width data.
• Study ecological responses to past climate change in Patagonian forests using the growth record.

Strengths

• Data spans 434 years, from 410 to -24 calendar years BP.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
• Provides a dated proxy record for a Southern Hemisphere location (Chubut, Argentina).

Limitations

• Temporal coverage ends at -24 BP (approximately 1974 CE), with no updates since the original 1974 publication.
• Specific sample depth, measurement statistics, and climate parameter correlations are not provided in the basic description.
• Geographic coverage is limited to a single site in Argentina, reducing regional representativeness.
