Waihora Lagoon Tree Ring Chronology from 300 to 35 BC

Tree ring width measurements from the Waihora Lagoon site in New Zealand, used as a proxy for past climate conditions. The chronology covers 335 years, from 300 to 35 calendar years before present. It was archived by NOAA's National Centers for Environmental Information under its Paleoclimatology program.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width time-series.
• Calibrate regional climate models by comparing the proxy chronology with other paleoclimate records.
• Analyze the frequency of extreme climate events in pre-industrial New Zealand via ring width deviations.
• Establish a dated master chronology for the region to support the analysis of other subfossil wood samples.

Strengths

• Time series spans 335 years, providing a multi-century climate record.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset contains only one primary proxy variable (tree ring width), limiting multivariate analysis.
• Temporal coverage ends at 35 BC, with no data for more recent millennia.
• Sample size and replication depth for individual years are unknown from the provided metadata.
