Spruce Creek Tree Ring Chronology From Yukon Territory

Tree ring width data from the Spruce Creek site in Yukon Territory, Canada, provides a paleoclimate record. The chronology spans 407 years, from 380 to -27 calendar years before present. NOAA National Centers for Environmental Information (NCEI) archives this study, which was last updated in 1977.

Use Cases

• Reconstruct past temperature or precipitation anomalies using tree ring width as a proxy climate indicator.
• Calibrate the chronology against other regional records using the calendar year before present (BP) time axis.
• Analyze growth patterns and potential climate stress events within the 407-year time series.

Strengths

• 407-year continuous chronology from 380 to -27 BP.
• Data is archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data recency is low, with a last update date of 1977.
• Specific sample depth, measurement methods, and climate parameter correlations are not detailed in the provided description.
