New Zealand Tree Ring Chronology from Takahe Stream (110 to -29 BP)

Tree ring width measurements from the Takahe Stream site in New Zealand, covering a 139-year period from 110 to -29 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information (NCEI) World Data Service for Paleoclimatology. The data was published or last updated in the NOAA system in 1979.

Use Cases

• Reconstruct past climate variables like temperature or precipitation by analyzing the tree ring width parameter as a proxy.
• Calibrate and validate climate models for the New Zealand region using the 139-year chronology.
• Perform cross-dating of other tree-ring records from the region using the established time series.
• Study the response of local tree species to climatic events within the recorded time period from 110 to -29 BP.

Strengths

• Data spans a continuous 139-year period (110 to -29 BP).
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Provides a specific geographic location for the study site in New Zealand.

Limitations

• Temporal coverage is relatively short (139 years) for long-term climate trend analysis.
• Data is temporally stale, with a last updated date in the NOAA system of 1979.
• Limited to a single geographic site (Takahe Stream), reducing regional representativeness.
