St. George Tree Ring Chronology from Manitoba, Canada (90 to -49 BP)

NOAA/WDS Paleoclimatology archives a tree-ring chronology from the St. George - Munsen Park site in Manitoba, Canada. The data provides annual tree-ring parameters covering the period from 90 to -49 calendar years before present. This study is maintained by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology and was last updated in 1999.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using annual tree-ring width parameters.
• Calibrate and validate climate models for the Manitoba region using the dated chronology from 90 to -49 BP.
• Analyze long-term ecological responses to climate events by examining the tree-ring growth series.

Strengths

• Data spans 140 years of annual resolution from 90 to -49 calendar years before present.
• Curated and archived by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Dataset is temporally stale, with a last update date of 1999.
• Specific parameters, sample size, and measurement details are not provided in the available description.
