Ironbound Island Tree Ring Chronology for Paleoclimate Reconstruction

285 to -32 calendar years before present (BP) of tree-ring width data from Ironbound Island, Maine, USA. This paleoclimatology dataset, archived by NOAA NCEI's World Data Service, provides parameters for dendrochronological studies. The data was last updated in the NOAA system in 1982.

Use Cases

• Reconstruct past climate variables like temperature or precipitation by analyzing the tree-ring width parameter as a proxy.
• Calibrate climate models by comparing the chronology from this specific geographic location against instrumental records.
• Study ecological responses to historical climate events by examining growth anomalies within the tree-ring time series.
• Perform cross-dating to validate or extend regional dendrochronological records using the Ironbound Island core samples.

Strengths

• Time series covers 317 years (285 to -32 BP), providing multi-century coverage.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Data recency is low, with a last recorded update in 1982, potentially missing modern methodological refinements.
• Geographic coverage is limited to a single island location (Maine, USA), which may not represent broader regional patterns.
• Specific sample depth, measurement parameters, and potential measurement noise are not detailed in the provided metadata.
