Willow Lake Insel Tree Ring Chronology From Northwest Territories

Tree ring width measurements from the Willow Lake Insel site in Canada's Northwest Territories, used for paleoclimate reconstruction. The chronology covers the period from 109 to -38 calendar years before present (BP). This archived study is maintained by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width time-series.
• Calibrate climate models by comparing the tree ring chronology with instrumental records.
• Analyze growth response patterns to environmental stressors in a subarctic region.
• Establish regional cross-dating master chronologies using the site's ring width data.

Strengths

• Data is archived by the authoritative NOAA World Data Service for Paleoclimatology.
• Chronology provides a multi-century time-series from 109 to -38 BP.

Limitations

• The dataset's last known update was in 1988, indicating potential staleness.
• Specific sample size, measurement methods, and raw data formats are not provided in the description.
