Tree ring data from Boundary Bog in Saskatchewan, Canada, provides a 315-year chronology for paleoclimate analysis. The dataset covers the period from 268 to -47 calendar years before present, calibrated to approximately 268 BC to 47 BC. NOAA National Centers for Environmental Information archives this study, which was last updated in 1997.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing annual tree-ring width variations.
- Calibrate radiocarbon dating models using the precisely dated tree-ring chronology.
- Study the frequency of environmental stressors, such as droughts, recorded in the ring density or width parameters.
- Compare this Northern Hemisphere tree-ring series with other proxy records to validate regional climate patterns.
Strengths
- 315-year continuous chronology provides a multi-century climate record.
- Geographic location in Saskatchewan offers data for a specific region of central Canada.
- Data is archived and curated by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends around 47 BC, offering no data for the modern or recent historical era.
- Data is from a single site (Boundary Bog), limiting spatial representativeness.
- The dataset was last updated in 1997, indicating potential staleness in metadata or availability.
