Crater Lake Tree Ring Chronology from 374 to -42 BP

Tree ring width measurements from Tsuga mertensiana trees at Crater Lake East Low, Oregon, USA, provide a paleoclimate record. The chronology covers 416 years, from 374 to -42 calendar years before present. Data is archived by NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology, with a study type of Tree Ring.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width time-series.
• Calibrate the tree ring chronology against other paleoclimate proxies using the documented calendar year BP timeline.
• Study growth patterns of Tsuga mertensiana (TSME) in response to documented volcanic events near Crater Lake.
• Validate climate model simulations for the Oregon region over the 416-year period covered by the record.

Strengths

• Chronology spans a continuous 416-year period (374 to -42 BP).
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Specific geographic location (Crater Lake, Oregon, USA) and tree species (Tsuga mertensiana) are documented.

Limitations

• Temporal coverage ends at -42 BP (approximately 1992 CE), with no updates since the original 1992 publication.
• Sample size (number of tree cores) and replication statistics are unknown from the provided metadata.
• The dataset may lack accompanying instrumental climate data for direct calibration over the full period.
