Tree ring width data from the Yakutat Gravel Pit Outer Moraine in Alaska, used for paleoclimate studies. The chronology covers 469 years, from 424 to -45 calendar years before present. Data was archived by NOAA's National Centers for Environmental Information in 1995.
Use Cases
- Reconstruct past temperature or precipitation anomalies using annual tree ring width measurements.
- Calibrate and validate regional climate models by comparing simulated data with the proxy tree ring chronology.
- Analyze the timing of glacial advances or retreats in southeastern Alaska by correlating the moraine site chronology with other paleo-records.
- Study extreme climate events during the late Holocene period captured in the ring width series.
Strengths
- Chronology spans 469 years, providing a multi-century climate record.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- The dataset is temporally stale, with a last update date of 1995.
- Sample size and replication depth for the tree ring series are unknown from the description.
- Geographic coverage is limited to a single moraine site in Yakutat, Alaska.
