Yakutat Situk River Valley Tree Ring Chronology from 125 to -46 BP

Alaska tree ring data provides a paleoclimate record for the Yakutat Situk River Valley. The chronology spans from 125 to -46 calendar years before present. NOAA National Centers for Environmental Information archived this study in 1996.

Use Cases

• Calibrating climate models using the tree ring width chronology as a proxy for past temperature or precipitation.
• Analyzing growth anomaly years within the time-series to identify extreme historical climate events.
• Comparing this Alaskan tree ring chronology with other regional series to study spatial climate patterns.

Strengths

• Chronology covers a 171-year time period from 125 to -46 BP.
• Data is archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Data has not been updated since its archival in 1996, limiting contemporary analysis methods.
• The specific sample depth, measurement parameters, and site details are not provided in the basic description.
