Nome Creek Tree Ring Chronology For Climate Reconstruction

Tree ring width data from a site below treeline near Nome Creek, Alaska, provides a proxy record for past climate conditions. The chronology spans 214 years, from 165 to -49 calendar years before present. This archived paleoclimatology study is maintained by NOAA's National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width time-series.
• Calibrate the chronology against known climate events using the provided calendar years before present (BP) index.
• Study ecological growth limits at treeline boundaries using the site's specific geographic location in Alaska.
• Compare this local record with other regional ITRDB chronologies to assess spatial climate patterns.

Strengths

• Data spans a 214-year period, providing a multi-century climate proxy.
• Archived within the authoritative International Tree-Ring Data Bank (ITRDB) and NOAA WDS for Paleoclimatology.

Limitations

• Temporal coverage ends at -49 BP (approximately 49 AD), lacking recent centuries for modern comparison.
• Data is from a single site (Nome Creek), limiting spatial representativeness for broader Alaska.
• Last metadata update was in 1999, indicating potential staleness in documentation or availability.
