Alaskan Tree Ring Chronology from Swede Point Taku Inlet

NOAA's World Data Service for Paleoclimatology archives this tree ring chronology from the Swede Point Taku Inlet area near Juneau, Alaska. The data provides a paleoclimate record spanning 138 calendar years, from 102 to -36 years before present. It was published by the NOAA National Centers for Environmental Information in 1986.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree-ring width series.
• Calibrate the chronology against known climate events using the calendar years before present (BP) time index.
• Study climate sensitivity in coastal Alaskan forests by correlating ring parameters with modern instrumental records.

Strengths

• Data spans 138 calendar years, providing a multi-decadal climate record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to 138 years, which is short for some paleoclimate studies.
• The dataset was last updated in 1986, indicating potential staleness in metadata or methods.
• Specific parameters and measurement details are only available in the full metadata.
