A tree-ring chronology from Cream Creek, New Zealand, covering the period from 490 to 28 calendar years before present. The dataset provides parameters for dendroclimatological analysis and is archived by NOAA's World Data Service for Paleoclimatology. Data was published in 1978.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology.
- Calibrate radiocarbon dates for the New Zealand region using the dated tree-ring series.
- Analyze climate periodicity and extreme events by examining the annual-resolution ring-width data.
- Compare this Southern Hemisphere tree-ring record with other proxy archives to study hemispheric climate teleconnections.
Strengths
- Covers a 462-year period (490 to 28 BP) providing a multi-century climate record.
- Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- The dataset is temporally stale, with a last update date of 1978.
- The sample size (number of tree cores or series) is unknown, which limits assessment of statistical robustness.
- Geographic coverage is limited to a single site (Cream Creek) in New Zealand.
