St. Anne River Tree Ring Chronology from 546 to -32 BP

Tree ring width measurements from the St. Anne River site in Quebec, Canada, used for paleoclimate reconstruction. The chronology spans 578 years, from 546 to -32 calendar years before present. The dataset was archived by NOAA NCEI's World Data Service for Paleoclimatology, with a last update recorded in 1982.

Use Cases

• Calibrate climate models by comparing tree ring width variations against known historical climate events.
• Reconstruct annual temperature or precipitation anomalies for Quebec over a 578-year period using the ring width time series.
• Analyze growth response and resilience of boreal tree species to long-term environmental changes.
• Cross-date and validate other tree ring chronologies from the North American boreal region.

Strengths

• 578-year continuous chronology from 546 to -32 BP provides a long-term environmental record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1982, indicating it may not reflect modern analytical standards or recent discoveries.
• Specific sample size, replication statistics, and measurement precision are unknown from the provided metadata.
• Geographic coverage is limited to a single site in Quebec, Canada.
