Buffalo Lake Tree Ring Chronology From Northwest Territories

NOAA/WDS Paleoclimatology archives a tree ring chronology dataset from Buffalo Lake, Northwest Territories, Canada. The data provides parameters for climate reconstruction covering a period from 108 to -38 calendar years before present. This study was published by NOAA National Centers for Environmental Information in 1988.

Use Cases

• Reconstruct past temperature or precipitation anomalies using tree ring width parameters.
• Calibrate climate models by comparing the tree ring chronology with known historical climate events.
• Analyze long-term ecological trends in the Northwest Territories region from the provided time series.

Strengths

• Data spans 146 calendar years (from 108 to -38 BP), providing a multi-century climate proxy.
• Archived by the authoritative NOAA World Data Service for Paleoclimatology, ensuring formal curation.

Limitations

• Dataset is temporally stale, with a last update recorded in 1988, potentially missing modern analytical methods.
• Geographic coverage is limited to a single site (Buffalo Lake), reducing regional representativeness.
• Specific sample size, row count, and measurement parameters are unknown from the provided metadata.
