Coppermine River Tree Ring Chronology from 522 to -27 BP

NOAA/WDS Paleoclimatology archives a tree ring chronology dataset from the Coppermine River region in Canada's Northwest Territories. The data covers a time period from 522 to -27 calendar years before present (BP), representing paleoclimate proxies. This study was contributed by Jacoby and is managed by NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using tree ring width measurements as a proxy.
• Calibrate climate models by comparing the tree ring chronology with known historical climate events.
• Analyze long-term climate trends in the subarctic region over the 549-year period covered by the data.
• Study ecological responses to climate change by examining growth patterns in the Coppermine River tree ring series.

Strengths

• Covers a 549-year time period from 522 to -27 BP, providing a multi-century climate record.
• Archived and maintained by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• The dataset's last documented update was in 1977, indicating the record may be temporally stale.
• Specific sample size, measurement parameters, and data formats are not provided in the available metadata.
