Alaskan Tree Ring Chronology from Starrigawan Old Sitka (345 to -36 BP)

NOAA/WDS Paleoclimatology archives a tree ring chronology from the Starrigawan Old Sitka site in Alaska. The dataset provides proxy climate data covering a period from 345 to -36 calendar years before present. It is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a proxy.
• Calibrate climate models by comparing the tree-ring time-series data with other paleoclimate records for the Alaska region.
• Analyze long-term climate trends and variability over a nearly 400-year period before present from the dated ring sequences.
• Study ecological responses to historical climate events by examining growth patterns in the tree-ring parameters.

Strengths

• Temporal coverage spans approximately 381 calendar years (345 to -36 BP).
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.

Limitations

• Dataset is temporally stale, with a last update recorded in 1986.
• Specific parameters, sample size, and measurement details are not provided in the available metadata.
