Michigan Tree Ring Chronology from 322 to 103 BC

Tree ring width measurements from an oxbow site in Michigan, United States, provide a 219-year climate proxy record. The chronology covers the period from 322 to 103 calendar years before present (BP), corresponding to the late pre-Common Era. Data is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree ring width series.
• Calibrate the tree ring chronology against other regional paleoclimate proxies using its documented temporal coverage.
• Study growth patterns and environmental stressors for the specific tree species sampled at the Michigan oxbow location.
• Validate climate model simulations for the late pre-Common Era period using this high-resolution proxy record.

Strengths

• Covers a continuous 219-year period from 322 to 103 BP.
• Geographically specific to a documented site in Michigan, USA.
• Part of the authoritative NOAA/NCEI World Data Service for Paleoclimatology archive.

Limitations

• Sample size and replication depth (number of cores/trees) are unknown from the provided metadata.
• The record ends over 2100 years ago, limiting direct analysis of recent climate change.
• Potential geographic bias as data comes from a single location.
