Gunisao Lake Tree Ring Chronology for Paleoclimate Study

NOAA NCEI archives a tree-ring chronology from Gunisao Lake in Manitoba, Canada. The data provides paleoclimate parameters covering a period from 54 to -38 calendar years before present. This dataset was published by the NOAA World Data Service for Paleoclimatology in 1988.

Use Cases

• Calibrating climate models using tree-ring width as a proxy for past temperature or precipitation conditions.
• Analyzing the chronology for extreme climatic events or volcanic signals within the 92-year time span.
• Correlating the Gunisao Lake series with other regional chronologies to reconstruct broader climate patterns.
• Studying the response of tree growth to environmental changes in the specific geographic location of Manitoba, Canada.

Strengths

• Data spans a 92-year period (54 to -38 BP), providing a discrete historical snapshot.
• Sourced from the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to under 100 years, restricting analysis of long-term climate trends.
• Data is geographically specific to a single lake site in Manitoba, limiting regional generalizability.
• The dataset was last updated in 1988, potentially lacking modern reanalysis or methodological improvements.
