Tree Ring Chronology from Cusac Mine in British Columbia

NOAA NCEI archives this tree ring dataset for paleoclimate reconstruction from the Cusac Mine site in British Columbia, Canada. The data provides a 235-year chronology, covering the period from 183 to -52 calendar years before present. The National Centers for Environmental Information (NCEI) published this study in 2002.

Use Cases

• Calibrating climate models by comparing tree ring width variations from this chronology with instrumental climate records.
• Reconstructing past temperature or precipitation anomalies for British Columbia using the site's tree ring parameters.
• Analyzing growth trends and environmental stressors in Abies lasiocarpa (ABLA) populations over a 235-year period.
• Cross-dating this ITRDB CANA364 chronology with other regional tree ring series to validate climate signals.

Strengths

• Covers a 235-year time period (183 to -52 BP).
• Part of the International Tree-Ring Data Bank (ITRDB), ensuring standardized format.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, last updated in 2002.
• Sample size and replication depth for the tree ring series are unknown.
• Geographic scope is limited to a single mine site in British Columbia.
