Tree Ring Chronology From Saskatchewan Borehole Site

91 calendar years of tree ring data, from 47 to -44 years before present, provide a paleoclimate record. The dataset is part of the NOAA/WDS Paleoclimatology archive, specifically from the Boreas SSA G4I3M Site 3 study. It was archived by NOAA NCEI and last updated in 1994.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing annual tree ring width variations.
• Calibrate radiocarbon dating or other chronological models using the dated tree ring sequence.
• Study the response of Abies balsamea (ABBA) tree growth to documented historical climate events within the 91-year period.
• Compare this local tree ring chronology with other regional proxies to validate broader climate reconstructions.

Strengths

• Covers a specific 91-year temporal sequence suitable for analyzing multi-decadal climate patterns.
• Geographically precise data from a single site (Boreas SSA G4I3M Site 3) in Saskatchewan, Canada.
• Part of the authoritative NOAA/WDS Paleoclimatology archive, ensuring standardized metadata and preservation.

Limitations

• Temporal coverage is relatively short (91 years) for long-term paleoclimate trend analysis.
• Data is from a single site, limiting spatial representativeness for regional studies.
• The dataset was last updated in 1994 and may not reflect more recent methodological advances or corrections.
