Tree Ring Chronology From St. George, Manitoba For Paleoclimate Analysis

A 144-year tree ring chronology from the Bruce Park site in St. George, Manitoba, Canada, covering the period from 95 to -49 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information World Data Service for Paleoclimatology. This paleoclimate study was last updated in 1999.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width chronology.
• Calibrate climate models for the Quaternary period using the dated proxy record from 95 to -49 BP.
• Study regional climate events in Manitoba by examining the annual resolution time series data.
• Compare this chronology with other ITRDB series (e.g., ITRDB CANA177) to assess spatial climate patterns.

Strengths

• Time series covers a 144-year period (95 to -49 BP) providing a multi-decadal climate record.
• Data is part of the authoritative International Tree-Ring Data Bank (ITRDB) collection, ensuring standardized formatting.

Limitations

• The dataset is temporally stale, with a last update recorded in 1999, limiting integration with recent studies.
• Geographic coverage is limited to a single site (Bruce Park, St. George), reducing representativeness for broader regions.
• The small temporal span (144 years) may be insufficient for analyzing long-term, low-frequency climate cycles.
