Crater Lake Tree-Ring Chronology From 353 to -42 BP

A 395-year tree-ring chronology from Tsuga mertensiana (mountain hemlock) trees at Crater Lake West Low, Oregon, USA, covering the period from 353 to -42 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information World Data Service for Paleoclimatology. It was last updated in the NOAA system in 1992.

Use Cases

• Reconstruct annual temperature or precipitation anomalies for the Crater Lake region using the tree-ring width index as a proxy.
• Calibrate the tree-ring chronology against known climate events within the 353 to -42 BP timeframe.
• Analyze growth trends and extreme years in the Tsuga mertensiana ring-width series for ecological studies.
• Compare this Tsuga mertensiana chronology with other regional tree-ring datasets to validate climate signals.

Strengths

• Covers a continuous 395-year period from 353 to -42 calendar years BP.
• Sourced from a recognized authoritative repository, NOAA NCEI WDS for Paleoclimatology.
• Provides a species-specific (Tsuga mertensiana) chronology from a defined geographic location.

Limitations

• The dataset's last known update was in 1992, indicating potential staleness in metadata or availability.
• Sample size (number of tree cores) and replication statistics are unknown from the provided description.
• Geographic coverage is limited to a single site at Crater Lake West Low, Oregon.
