Olympic Peninsula Tree Ring Chronology from 556 to 37 BCE

NOAA/WDS Paleoclimatology archives a tree-ring chronology from a Pseudotsuga menziesii (Douglas-fir) sample at the Olympic Road 3116 site in Washington, USA. The data covers a 593-year period from 556 to 37 years before present (calendar years BCE). This study was contributed by Earle and archived by NOAA's National Centers for Environmental Information.

Use Cases

• Reconstruct annual temperature or precipitation anomalies for the Olympic Peninsula using the tree-ring width time-series.
• Calibrate climate models by comparing the 593-year ring-width chronology with known historical climate events.
• Analyze growth patterns in Pseudotsuga menziesii (PSME) to study ecological responses to environmental changes over six centuries.
• Establish cross-dating references for other tree-ring studies in the Pacific Northwest region using this ITRDB series (WA088).

Strengths

• Covers a substantial 593-year time period (556 to -37 BP).
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection curated by NOAA/NCEI.
• Provides a site-specific chronology for a key tree species (Pseudotsuga menziesii) in Washington.

Limitations

• Data is from a single tree sample (site WA088), limiting spatial representativeness.
• The last update was in 1987, potentially lacking modern reanalysis or updated metadata.
