Bruny Island Tree-Ring Chronology from 408 to 25 BC

NOAA/WDS Paleoclimatology archives a tree-ring dataset from Bruny Island, Tasmania. The chronology spans 433 years, from 408 to 25 calendar years before present. NOAA National Centers for Environmental Information (NCEI) published this paleoclimate study.

Use Cases

• Reconstruct past temperature or precipitation anomalies using annual tree-ring width measurements.
• Calibrate and validate climate model simulations for the Southern Hemisphere over the 433-year period.
• Analyze growth patterns and extreme events within the chronology to identify historical climate extremes.
• Compare this Tasmanian chronology with other Southern Hemisphere tree-ring records for hemispheric climate signals.

Strengths

• Time series covers a 433-year period from 408 to 25 BC.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last update recorded in 1975.
• Specific sample depth, measurement parameters, and potential uncertainties are not provided in the basic metadata.
