Newfoundland Tree Ring Chronology from 316 to -47 BP

Tree ring data from Medusa Bay, Newfoundland, Canada, archived by NOAA's World Data Service for Paleoclimatology. The chronology spans 363 years, from 316 to -47 calendar years before present. This dataset was published by NOAA NCEI and last updated in 1997.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology.
• Calibrate radiocarbon dating curves by aligning the tree-ring series with known calendar years.
• Analyze climate forcing events by identifying narrow or wide ring sequences within the 363-year record.
• Compare North Atlantic climate proxies by correlating this Newfoundland chronology with other ITRDB series.

Strengths
