Wizard Island Tree Ring Chronology from 297 to -42 BP

Tree ring width measurements from a site on Wizard Island, Oregon, providing a paleoclimate record. The chronology covers a 339-year period from 297 to -42 calendar years before present. Data is archived by NOAA NCEI's World Data Service for Paleoclimatology and was last updated in 1992.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width time-series.
• Calibrate radiocarbon dating or other chronological models with the dated annual ring sequence.
• Analyze climate sensitivity and growth response by correlating ring-width indices with instrumental climate data.
• Compare the Wizard Island chronology with other regional tree-ring records to identify broad climate patterns.

Strengths

• 339-year continuous chronology from 297 to -42 BP provides a multi-century climate record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset is temporally stale, with no updates since its publication in 1992.
• Limited geographic scope to a single site (Wizard Island, Oregon) may not represent regional patterns.
• Unknown sample depth (number of tree cores) limits assessment of chronology robustness.
