New Zealand Tree Ring Chronology from Hauhungatahi Site B (620 to -42 BP)

NOAA/WDS Paleoclimatology archives tree ring data from the Hauhungatahi Site B near Tongariro, New Zealand. The chronology covers a period from 620 to -42 calendar years before present. This study is maintained by the NOAA National Centers for Environmental Information and was last updated in 1992.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing tree ring width variations over the 662-year chronology.
• Calibrate radiocarbon dating or validate other paleoclimate proxies using the dated tree ring series.
• Study volcanic climate impacts by correlating ring anomalies from this Tongariro site with known eruption events.
• Model forest growth responses to long-term climate change using the site-specific tree ring parameters.

Strengths

• Chronology spans 662 calendar years (620 to -42 BP), providing multi-century coverage.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1992, indicating potential staleness in metadata or methods.
• Specific parameters, sample depth, and measurement details are unknown without accessing full metadata.
