St. George Tree Ring Chronology from Manitoba, 95 to -48 BP

143 calendar years of tree-ring width data from St. Vital Park in Manitoba, Canada, covering the period 95 to -48 years before present. The dataset is part of the NOAA/WDS Paleoclimatology archive, specifically the International Tree-Ring Data Bank (ITRDB) collection. It was published by NOAA National Centers for Environmental Information (NCEI) and last updated in 1998.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a climate proxy.
• Calibrate radiocarbon dating or other chronological models by cross-referencing the dated tree-ring series.
• Analyze growth patterns and environmental stress events recorded in the ring-width parameter for specific years.
• Compare this local chronology from Manitoba with other ITRDB series to study regional climate teleconnections.

Strengths

• Covers a specific 143-year period (95 to -48 BP) for high-resolution temporal analysis.
• Part of the authoritative, curated International Tree-Ring Data Bank (ITRDB) collection from NOAA/NCEI.
• Provides a geographically specific record from St. Vital Park, Manitoba, Canada.

Limitations

• Small temporal coverage of 143 years limits analysis of long-term, multi-century climate trends.
• Data is geographically limited to a single site in Manitoba, reducing regional representativeness.
• The dataset is temporally stale, with no updates since its publication in 1998.
