Alaskan Tree Ring Chronology from Tok River (143 to -36 BP)

143 to -36 calendar years before present (BP) of tree ring parameters from the Tok River area in Alaska, United States. The dataset is a paleoclimatology study archived by the NOAA National Centers for Environmental Information (NCEI) under the World Data Service for Paleoclimatology. Data was last updated in the NOAA system in 1986.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using tree ring width or density parameters.
• Calibrate climate models by comparing the tree ring chronology with other proxy records for the 143 to -36 BP period.
• Analyze long-term ecological trends and forest growth responses in the specific geographic location of the Tok River, Alaska.

Strengths

• Covers a 179-year time period from 143 to -36 calendar years before present.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last recorded update in 1986.
• Specific parameters, sample size (row count), and measurement methodologies are not detailed in the provided metadata.
