Massachusetts Cedar Swamp Tree Ring Chronology 109 BC to 66 AD

NOAA's National Centers for Environmental Information provides a tree-ring chronology from the Acushnet Cedar Swamp in Massachusetts. The data covers the period from 109 BC to 66 AD, offering a proxy climate record for the northeastern United States. This archived study was last updated in 2016.

Use Cases

• Reconstruct past temperature or precipitation variations by analyzing the tree-ring width chronology.
• Calibrate climate models for the northeastern US using the high-resolution annual proxy data spanning 175 years.
• Study extreme climate events or periods like the Roman Warm Period using the dated ring-width series.
• Perform cross-dating with other regional tree-ring chronologies using the standardized index values.

Strengths

• Covers a specific 175-year period from 109 BC to 66 AD.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Provides a high-resolution annual climate proxy for a specific geographic location.

Limitations

• Temporal coverage is limited to a specific 175-year window, not a continuous long record.
• Data is specific to a single swamp site in Massachusetts, limiting broad spatial analysis.
• The dataset was last updated in 2016 and may not reflect the most recent archival standards.
