Oxbow Tree Ring Chronology for Michigan Climate Reconstruction

Tree ring width measurements from the Oxbow site in Michigan, United States, covering the period from 307 to 86 calendar years before present. The data are archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. This study is part of the International Tree-Ring Data Bank collection.

Use Cases

• Reconstruct annual temperature or precipitation anomalies from the tree ring width time-series.
• Calibrate the chronology against other regional proxy records using the calendar year BP dating.
• Analyze growth patterns and climate sensitivity for the specific tree species at the Michigan site.
• Validate climate model simulations for the past millennium using the high-resolution proxy data.

Strengths

• Time-series covers a continuous 221-year period (307 to 86 BP).
• Data is part of the authoritative International Tree-Ring Data Bank (ITRDB) collection.
• Includes precise geographic location metadata for the site in Michigan, USA.

Limitations

• Temporal coverage is limited to a specific 221-year window, not a full millennial record.
• Sample size and replication statistics for the tree-ring series are unknown from the description.
• The dataset's last update date (1864-01-01) is implausible, indicating potential metadata staleness.
