Alaskan Tree Ring Chronology from 16 to -35 Years Before Present

Tree ring width measurements from Russelfjord Southern End E in Alaska provide a 51-year chronology for paleoclimate analysis. NOAA National Centers for Environmental Information (NCEI) archives this data under its Paleoclimatology program. The dataset was last updated in 1985.

Use Cases

• Calibrating radiocarbon dates for the period 16 to -35 calendar years BP using the tree-ring chronology.
• Analyzing inter-annual climate variability in coastal Alaska from the tree-ring width parameter.
• Reconstructing local temperature or precipitation signals for southern Alaska from the dated tree-ring series.

Strengths

• Covers a specific 51-year time period (16 to -35 calendar years BP).
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Very short temporal coverage of only 51 years limits long-term climate trend analysis.
• Data is temporally stale, with no updates since its 1985 publication.
