BOREAS TE-22: Tree Core Samples for Growth Studies

Summer 1994 tree cores from the Northern and Southern Study Areas (NSA and SSA) of the BOREAS project support historical growth analysis. The BOREAS TE-22 team collected these samples to relate tree ring data to ecosystem modeling activities. A sample of file types from the core analysis is provided.

Use Cases

• Historical growth modeling based on tree ring width data.
• Calibrating ecosystem models with site-specific vegetation chronologies.
• Studying plant characteristics and species distribution in boreal regions.

Strengths

• Data collected under the structured, large-scale BOREAS (Boreal Ecosystem–Atmosphere Study) project.
• Provides physical tree core samples from multiple sites across two distinct study areas.
• Supports temporal analysis with data anchored to a specific collection period (summer 1994).

Limitations

• Key metadata conflicts: 'last updated' dates differ significantly (1994 vs. 2026) across sources.
• Column names and detailed data structure are unknown, limiting immediate analytical utility.
• Dataset scale (row count, file size) is unspecified across all sources.
