Little Maumelle River Tree Ring Chronology from 418 to 35 BC

Tree ring data from Arkansas, USA, provides a 453-year chronology from 418 to 35 BC. The dataset is part of the NOAA/WDS Paleoclimatology archive and was contributed by researcher Stahle. It was last updated in the NOAA system in 1985.

Use Cases

• Reconstruct annual precipitation or drought indices for Arkansas using the tree ring width parameter.
• Calibrate regional climate models by comparing the 453-year tree ring chronology with other paleoclimate proxies.
• Analyze growth anomalies within the time-series to identify extreme climatic events, such as multi-year droughts, during the period 418-35 BC.
• Cross-date archaeological wood samples from the southeastern US by matching patterns in the tree ring chronology.

Strengths

• Covers a continuous 453-year time period (418 to 35 BC).
• Sourced from the authoritative NOAA National Centers for Environmental Information (NCEI).
• Geographic location is precisely defined as Arkansas, United States.

Limitations

• Data is temporally stale, with a last update recorded in 1985.
• The sample size (number of tree cores or sites) is unknown, limiting assessment of statistical robustness.
• The calendar year scale (years before present) requires conversion for standard historical analysis.
