New Zealand Tree Ring Chronology from Logos Hill

Tree ring parameters from the Logos Hill site in New Zealand provide a 269-year chronology from 240 to -29 calendar years before present. This paleoclimatology study is archived by the NOAA National Centers for Environmental Information under its World Data Service. The data was published in 1979.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree ring width time-series.
• Calibrate radiocarbon dating curves for the New Zealand region using the dated tree ring chronology.
• Analyze the frequency of narrow rings (a proxy for environmental stress) across the 269-year record.
• Compare this Southern Hemisphere tree ring series with Northern Hemisphere chronologies to study global climate patterns.

Strengths

• Covers a continuous 269-year time period (240 to -29 BP).
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset is temporally stale, with a last update date of 1979.
• The specific parameters (e.g., ring width, density) and sample size are not detailed in the provided metadata.
• Geographic coverage is limited to a single site (Logos Hill) in New Zealand.
