New Zealand Tree Ring Chronology from Tarkus Knob (424 to -28 BP)

NOAA/WDS Paleoclimatology archives a tree-ring chronology from the Tarkus Knob site in New Zealand. The dataset provides parameters for dendrochronological analysis covering the period from 424 to -28 calendar years before present. It is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width or density parameters.
• Calibrate radiocarbon dating or other chronological models with the dated tree-ring series.
• Analyze climate periodicity and extreme events over the 452-year span recorded in the chronology.
• Compare Southern Hemisphere climate proxy records using the geographic location data for New Zealand.

Strengths

• Temporal coverage spans 452 calendar years (424 to -28 BP).
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last update date recorded as 1978.
• Specific parameters, sample size, and measurement methods are not detailed in the provided description.
