Westward Lake Tree Ring Chronology From Ontario, Canada

NOAA/WDS Paleoclimatology archives a tree-ring chronology from Westward Lake, Ontario, Canada. The dataset covers a 665-year period from 763 to 98 calendar years before present. It was contributed by Guyette and is maintained by NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using tree-ring width measurements.
• Calibrate radiocarbon dating or other chronological models against the 665-year tree-ring series.
• Analyze long-term ecological growth patterns in boreal forests from the Ontario site data.
• Validate regional climate model simulations for centuries preceding instrumental records.

Strengths

• 665-year continuous chronology from 763 to 98 BP.
• Geographically specific data from a single site in Ontario, Canada.

Limitations

• Unknown sample depth (number of tree cores) limits assessment of statistical robustness.
• Data is temporally stale, with a last update date recorded as 1852.
• Lack of column details prevents understanding of specific measured parameters.
