Great Dismal Swamp Tree Ring Chronology From 120 to 25 BC

NOAA/WDS Paleoclimatology archives a tree-ring chronology from the Great Dismal Swamp in Virginia, USA. The data covers a 145-year period from 120 to 25 calendar years before present (BP). It was published by NOAA National Centers for Environmental Information in 1975.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree-ring width chronology.
• Calibrate radiocarbon dates for the region by cross-referencing the established tree-ring time series.
• Analyze growth patterns in the chronology to identify periods of environmental stress or favorable conditions.

Strengths

• Data spans a continuous 145-year period from 120 to 25 BP.
• Sourced from the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Temporal coverage is relatively short for long-term climate trend analysis.
• Data is geographically limited to a single site in Virginia.
• Dataset is stale, last updated in 1975, with no recent revisions.
