Saganaga Lake Tree Ring Chronology for Paleoclimate Analysis

Tree ring width data from Saganaga Lake in Minnesota, USA, provides a paleoclimate record. The chronology covers 345 years, from 307 to -38 calendar years before present. The dataset was archived by NOAA NCEI's World Data Service for Paleoclimatology, with a last recorded update in 1988.

Use Cases

• Reconstruct past temperature or precipitation anomalies using tree ring width as a proxy.
• Calibrate climate models by comparing the tree ring chronology with other paleoclimate records.
• Analyze long-term climate trends in the Minnesota region over a 345-year period.
• Study the response of boreal forest tree growth to historical climate events captured in the ring series.

Strengths

• Covers a 345-year time period (307 to -38 BP).
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last update recorded in 1988.
• Geographic coverage is limited to a single site in Minnesota, USA.
• Specific parameters, sample size, and measurement details are not provided in the available metadata.
