Peace-Athabasca Lake Level Reconstruction from Tree Rings

158 years of reconstructed lake level data for the Peace-Athabasca Delta in Saskatchewan, Canada, derived from paleolimnological and tree-ring parameters. The dataset, produced by the NOAA National Centers for Environmental Information, provides estimates of historical water levels from 140 to -17 calendar years before present. It is archived under the World Data Service for Paleoclimatology as a Lake Level Reconstruction study.

Use Cases

• Modeling historical lake level fluctuations using the reconstructed water level parameter.
• Correlating tree-ring width chronologies with the lake level reconstruction to validate proxy relationships.
• Analyzing centennial-scale hydrological trends in the Peace-Athabasca Delta for climate impact studies.
• Calibrating regional climate models with the 158-year paleolimnological record of water levels.

Strengths

• 158-year temporal coverage providing a multi-decadal climate context.
• Data includes multiple proxy parameters: lake levels, paleolimnology, and tree rings.
• Archived and maintained by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at -17 BP, indicating the core data may not extend into the recent instrumental period.
• Specific sample size, row count, and measurement resolution are unknown from the provided metadata.
• Geographic coverage is limited to a single delta system in Saskatchewan, Canada.
