Tasmanian Tree Ring Chronology from 408 BC

Tree ring width data from Sheepwash Creek in Tasmania, Australia, provides a climate proxy record. The chronology spans 433 years, from 408 to 25 BC, archived by NOAA's World Data Service for Paleoclimatology. This study was published in 1975.

Use Cases

• Calibrating Southern Hemisphere climate models using the tree ring width time-series.
• Analyzing inter-annual climate variability in Tasmania during the pre-Common Era period from the ring measurements.
• Reconstructing past temperature or precipitation anomalies for the region through statistical analysis of the chronology.

Strengths

• Data spans a 433-year period, offering a multi-century climate record.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at 25 BC, providing no data for the Common Era.
• Geographic scope is limited to a single site (Sheepwash Creek) in Tasmania.
