Wakuach Lake Tree Ring Chronology from Quebec (109 to -38 BP)

NOAA/WDS Paleoclimatology archives a tree ring chronology from Wakuach Lake, Quebec, Canada. The data provides annual tree ring measurements covering the period from 109 to -38 calendar years before present. This dataset was created by Schweingruber and last updated via the NOAA National Centers for Environmental Information in 1988.

Use Cases

• Reconstruct past temperature or precipitation anomalies using annual tree ring width measurements.
• Calibrate climate models by comparing the tree ring chronology against known historical climate events.
• Analyze growth trends and environmental stressors for the tree species at the Wakuach Lake site.
• Establish a dated timeline for regional environmental changes using the tree ring series as a proxy.

Strengths

• Time series covers a 147-year period (109 to -38 BP), providing a multi-decadal climate record.
• Data is archived and curated by the authoritative NOAA National Centers for Environmental Information.

Limitations

• Temporal coverage is limited to a specific 147-year window, not a continuous long-term record.
• Data is geographically specific to a single site (Wakuach Lake, Quebec), limiting broad spatial analysis.
• The dataset was last updated in 1988, and methodologies may not reflect modern standards.
