Kathleen Lake Tree Ring Chronology from Yukon Territory

Tree ring width data from Kathleen Lake in Canada's Yukon Territory provides a 331-year climate proxy record. The chronology spans from 283 to -48 calendar years before present, calibrated for calendar year conversion. NOAA National Centers for Environmental Information archives this paleoclimatology study, last updated in 1998.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing annual tree ring width variations.
• Calibrate climate models using the 331-year proxy record to validate historical climate simulations for the Yukon region.
• Study extreme climate events or periods of stress indicated by sequences of narrow tree rings in the chronology.
• Compare this high-latitude tree ring series with other paleoclimate proxies to analyze hemispheric climate patterns.

Strengths

• Provides a 331-year continuous paleoclimate proxy record (283 to -48 BP).
• Data is archived and curated by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at -48 BP (approximately 1998 CE), with no updates since the 1998 publication.
• The dataset's sample size, number of core samples, and specific measurement statistics are unknown from the description.
• Geographic coverage is limited to a single site (Kathleen Lake), which may not represent broader regional climate.
