Sheridan Mountain Tree Ring Chronology from 485 to -43 BP

NOAA/WDS Paleoclimatology archives a tree-ring dataset from the Sheridan Mountain site in Oregon, USA. The chronology spans 528 calendar years, from 485 to -43 years before present, for the species Tsuga mertensiana (TSME). This dataset is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation using annual tree-ring width measurements as a climate proxy.
• Calibrate climate models by comparing the tree-ring chronology with instrumental records for the region.
• Analyze growth patterns of Tsuga mertensiana (TSME) in response to documented historical climate events.
• Establish a dated chronology for the Sheridan Mountain site to support cross-dating with other regional tree-ring records.

Strengths

• Chronology covers a specific 528-year period (485 to -43 BP).
• Data is archived and curated by the authoritative NOAA National Centers for Environmental Information (NCEI).
• Dataset provides a geographically specific record for a site in Oregon, USA.

Limitations

• Temporal coverage ends at -43 BP (approximately 1993 CE), with no updates indicated since the last metadata update in 1993.
• Specific parameters, measurement units, and sample depth (number of tree cores) are not detailed in the provided description.
• Geographic coverage is limited to a single mountain site in Oregon, which may not be representative of broader regional climate.
