Tasmanian Tree Ring Chronology from 408 to -42 Years Before Present

Tree ring width measurements from Tasmania, Australia, provide a 450-year climate proxy record ending 42 years before the 1950 reference date. NOAA's National Centers for Environmental Information archives this paleoclimatology study for the World Data Service. The data was last updated in the repository in 1992.

Use Cases

• Calibrating regional climate models by comparing tree ring width variations against instrumental temperature records.
• Analyzing growth anomaly patterns within the chronology to identify extreme drought or cold events in Tasmanian history.
• Correlating the Tasmanian tree ring series with other Southern Hemisphere proxies to assess hemispheric climate synchronicity.
• Establishing a dated chronology for archaeological or ecological studies in the region using the provided calendar years BP.

Strengths

• Covers a 450-year period from 408 to -42 calendar years BP, providing a multi-century climate record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology, ensuring standardized metadata.

Limitations

• The data is temporally stale, with a last repository update recorded in 1992, potentially missing modern reanalysis.
• The raw sample size, replication statistics, and measurement precision are unknown from the provided description.
