Alaskan Tree Ring Chronology From 18 to -35 BP

Tree ring width chronology from the Russelfjord Southern End C site in Alaska, used for paleoclimate reconstruction. The data covers a 53-year period from 18 to -35 calendar years before present. This archived study is provided by NOAA's National Centers for Environmental Information and was last updated in 1985.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width parameter as a climate proxy.
• Calibrate the chronology against other regional proxy records using the provided calendar years before present (BP) time scale.
• Study environmental changes in coastal Alaska by correlating the tree ring data from this specific geographic location with known historical events.

Strengths

• Data originates from NOAA's authoritative World Data Service for Paleoclimatology.
• Covers a specific 53-year time period (18 to -35 BP) for high-resolution analysis.

Limitations

• The dataset is temporally stale, with a last update date of 1985, potentially lacking modern reanalysis.
• Limited geographic scope to a single site (Russelfjord Southern End C) in Alaska.
