Mount Te Aroha Tree Ring Chronology From 171 To -25 BP

A 196-year tree ring chronology from Mount Te Aroha, New Zealand, provides paleoclimate data for the period 171 to -25 calendar years before present. The dataset is archived by NOAA's World Data Service for Paleoclimatology as part of their tree ring study collection. This specific record was contributed by researcher Lamarche and was last updated in the NOAA system in 1975.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree ring width series.
• Calibrate radiocarbon dating curves for the New Zealand region using the dated chronology.
• Identify extreme climatic events, such as droughts or volcanic winters, from marker years in the ring sequence.
• Compare this Southern Hemisphere tree ring series with Northern Hemisphere chronologies to study global climate teleconnections.

Strengths

• Chronology covers 196 years, from 171 to -25 calendar years BP.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1975, indicating potential staleness versus modern analytical methods.
• Geographic coverage is limited to a single site (Mount Te Aroha), reducing regional representativeness.
• Specific measurement parameters (e.g., ring width, density) and sample depth are not detailed in the provided metadata.
