Tree ring width data from a logging road site near Yakutat, Alaska, provides a climate proxy record. The chronology spans 419 years, from 374 to -45 calendar years before present. This paleoclimatology study is archived by the NOAA National Centers for Environmental Information.
Use Cases
- Calibrate tree ring width variations against known climate events within the 419-year chronology.
- Reconstruct past temperature or precipitation anomalies for the Alsek River region using the ring width proxy.
- Compare this site's chronology with other ITRDB series to analyze spatial climate patterns in coastal Alaska.
Strengths
- Covers a continuous 419-year time period (374 to -45 BP).
- Part of the International Tree-Ring Data Bank (ITRDB), a standardized global archive.
Limitations
- Temporal coverage ends 45 years before present (1950 CE), lacking recent decades.
- Data is from a single site (ITRDB AK137), limiting spatial representativeness.
- Raw sample depth and replication statistics are unknown from provided metadata.
