Ohutu Ridge Tree Ring Chronology for New Zealand Paleoclimate

406 calendar years of tree ring data from the Ohutu Ridge site in New Zealand, covering the period from 365 to -41 years before present. This paleoclimatology study is archived by NOAA's National Centers for Environmental Information and was last updated in 1991. It is part of the World Data Service for Paleoclimatology and focuses on parameters derived from tree rings.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
• Calibrate climate models by comparing the proxy tree ring data with instrumental records for the New Zealand region.
• Analyze the temporal resolution of the chronology to identify specific climatic events within the 406-year span.
• Correlate the Ohutu Ridge series with other Southern Hemisphere tree ring datasets to assess regional climate patterns.

Strengths

• 406-year continuous chronology providing multi-century climate context.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last known update was in 1991, making it temporally stale for contemporary analysis without verification.
• Specific parameters, sample depth, and measurement columns are not detailed in the provided metadata.
