Murmashi Tree Ring Chronology for Russian Climate Reconstruction

Tree ring width data from Murmashi, Russia, provides a 277-year climate proxy record spanning from 235 to -42 calendar years before present. The NOAA National Centers for Environmental Information (NCEI) archives this paleoclimatology study for the World Data Service. This dataset was last updated in 1992.

Use Cases

• Reconstruct past temperature or precipitation anomalies by calibrating tree ring width series against instrumental climate data.
• Analyze growth trends and extreme events within the 277-year chronology to identify periods of environmental stress.
• Cross-date the Murmashi PISY (Pinus sylvestris) chronology with other regional tree ring datasets to validate climate signals.
• Calibrate radiocarbon dating curves using the precisely dated tree ring sequence from this boreal forest site.

Strengths

• 277-year continuous chronology from 235 to -42 BP provides a multi-century climate proxy.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data recency is low, with a last update in 1992, potentially missing modern methodological revisions.
• The specific sample depth (number of trees/cores) and measurement statistics are unknown from the provided metadata.
• Geographic coverage is limited to a single site (Murmashi) in Russia, limiting regional representativeness.
