NOAA NCEI archives this tree-ring dataset from Lassiter Swamp in Merchants Millpond State Park, North Carolina. It provides a paleoclimate record covering 460 years, from 426 to -34 calendar years before present. The data was published by the NOAA World Data Service for Paleoclimatology in 1984.
Use Cases
- Reconstruct past precipitation or temperature anomalies by analyzing the annual ring-width series.
- Calibrate the tree-ring chronology against other regional proxies using the documented calendar years before present.
- Study the frequency of environmental stressors, such as droughts, indicated by sequences of narrow rings in the time-series.
Strengths
- Covers a 460-year time period (426 to -34 BP) for long-term trend analysis.
- Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, last updated in 1984, potentially missing modern analytical refinements.
- Geographic scope is limited to a single swamp site in North Carolina, limiting regional generalizability.
- Specific sample depth, measurement variables, and potential missing years within the chronology are unknown from the description.
