Massachusetts Cedar Swamp Tree Ring Chronology from 77 to -65 BP

Tree ring width measurements from the Pearl - Walpole Cedar Swamp in Massachusetts, USA, used for paleoclimate reconstruction. The chronology covers the period from 77 to -65 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information's World Data Service for Paleoclimatology and was last updated in 2015.

Use Cases

• Calibrate climate models using the tree ring width time-series as a proxy for past temperature and precipitation.
• Analyze growth anomalies in the tree ring chronology to identify extreme climate events like droughts.
• Compare this chronology with other regional tree ring datasets to study spatial climate patterns.

Strengths

• Data spans 142 calendar years, from 77 to -65 BP.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is relatively short for long-term climate trend analysis.
• Data is geographically limited to a single swamp site in Massachusetts.
• The dataset has not been updated since 2015.
