682-year tree ring chronology from 664 to 18 BCE, providing a proxy record of past climate conditions. The dataset contains parameters of tree ring growth from alluvial logs in the St. George area of Manitoba, Canada. It is archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width parameter as a climate proxy.
- Calibrate radiocarbon dating curves by cross-referencing the absolute tree ring chronology with other dating methods.
- Study extreme hydrological events in the Assiniboine River basin by identifying signature patterns in the alluvial log ring sequences.
- Compare this North American tree ring series with other global paleoclimate records to analyze hemispheric climate teleconnections.
Strengths
- Covers a 682-year continuous time series from 664 to 18 BCE.
- Provides an absolute, dendrochronologically-dated proxy record for climate studies.
Limitations
- Temporal coverage ends over 2000 years ago, limiting analysis of recent climate change.
- Geographic scope is limited to a single site in Manitoba, Canada.
