Alaskan Treeline Tree Ring Chronology from Eagle Summit

A tree-ring chronology from the Eagle Summit treeline in Alaska, United States. The dataset covers 164 years, from 117 to -46 calendar years before present. It is an archived paleoclimatology study from the NOAA National Centers for Environmental Information, last updated in 1996.

Use Cases

• Reconstruct past summer temperatures using tree-ring width measurements from the Eagle Summit site.
• Analyze climate sensitivity and growth trends in Alaskan treeline ecosystems over a 164-year period.
• Calibrate and validate climate models with high-resolution proxy data from this specific geographic location.
• Study the response of boreal forest boundaries to climatic changes using this dated tree-ring series.

Strengths

• Data spans a continuous 164-year period (117 to -46 BP).
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is relatively short for long-term climate trend analysis.
• Data is geographically limited to a single site in Alaska.
• The dataset is stale, with a last recorded update in 1996.
