Argentine Tree Ring Chronology from 411 to -24 BP

411 to -24 calendar years before present (BP) of tree ring data from Rio Negro, Argentina, used for paleoclimate reconstruction. The dataset is part of the NOAA/WDS Paleoclimatology archive, specifically the Tree Ring study type. It was archived by NOAA National Centers for Environmental Information (NCEI).

Use Cases

• Reconstruct past temperature or precipitation anomalies in Patagonia by analyzing the tree ring width chronology.
• Calibrate radiocarbon dating curves by correlating the dated ring sequences with known volcanic or climatic events.
• Study climate forcing events, such as volcanic eruptions, by identifying narrow ring sequences within the chronology.
• Analyze long-term climate trends in South America by examining the ring width variance over the 435-year period.

Strengths

• Covers a 435-year period from 411 to -24 BP, providing a multi-century climate record.
• Sourced from the authoritative NOAA/WDS Paleoclimatology archive with standardized metadata.

Limitations

• The dataset's last update was in 1974, indicating potentially outdated collection or processing methods.
• Specific sample size, replication statistics, and measurement parameters (e.g., ring width, density) are not provided in the input.
• Geographic coverage is limited to a single site (Cerro Los Leones, Rio Negro, Argentina).
