Tree Ring Chronology From New Gaspe Spanning 414 Years

Tree ring width measurements from a site in Canada, providing a climate proxy record. The chronology covers 414 years, from 373 to -41 calendar years before present. Data is archived by NOAA's National Centers for Environmental Information and was last updated in 1991.

Use Cases

• Reconstruct annual temperature or precipitation anomalies from tree ring width measurements.
• Calibrate and validate climate model simulations for the past 400+ years using this proxy record.
• Analyze the frequency and magnitude of extreme climate events captured in the ring width series.
• Cross-date and synchronize this chronology with other regional tree ring records for broader climate studies.

Strengths

• 414-year continuous chronology from 373 to -41 BP.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Data has not been updated since 1991, potentially missing modern methodological refinements.
• Specific sample depth, replication statistics, and measurement parameters are not detailed in the provided metadata.
