Eastmain River Tree Ring Chronology from 211 to -38 BP

NOAA/WDS Paleoclimatology archives a tree-ring chronology from the Eastmain River region in Quebec, Canada. The data covers the period from 211 to -38 calendar years before present. This study was published by the NOAA National Centers for Environmental Information in 1988.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a proxy.
• Calibrate climate models by comparing the tree-ring time-series data against known historical climate events.
• Analyze long-term ecological trends in boreal forests using the dated tree-ring records.
• Cross-date this chronology with other regional tree-ring datasets to validate climate signals.

Strengths

• Data spans 249 years (211 to -38 BP), providing a multi-century climate record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Includes precise geographic location metadata for Quebec, Canada.

Limitations

• Temporal coverage ends at -38 BP, limiting analysis of the most recent millennia.
• Data was last updated in 1988, potentially lacking modern methodological refinements.
• Specific sample size, measurement parameters, and replication statistics are unknown from the description.
