Kodiak Island Tree Ring Chronology From 161 to -36 BP

161 to -36 calendar years before present (BP) of tree ring parameters from Isthmus, Kodiak Island, Alaska. This paleoclimatology study is archived by the NOAA National Centers for Environmental Information under the World Data Service. The data was last updated in 1986.

Use Cases

• Reconstruct past temperature or precipitation anomalies using tree ring width measurements.
• Calibrate climate models by comparing the chronology with known historical climate events.
• Analyze growth patterns to infer ecological responses to environmental changes over two centuries.

Strengths

• Time series covers a 197-year period from 161 to -36 BP.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset has not been updated since 1986, potentially missing modern analytical refinements.
• Specific sample size, row count, and measurement parameters are not provided in the available metadata.
