Central Kivalliq Glacial Dynamics from 2025 Field Campaign

49 observation stations were documented during a field campaign from July 31 to August 11, 2025, in the central Kivalliq region. The dataset includes site locations for ice-flow indicators, till sampling for geochemistry, and boulder/bedrock samples for cosmogenic isotope dating, compiled by Natural Resources Canada. Analytical results are reserved for future publications.

Use Cases

• Map ice-flow directions and relative chronology based on field-measured indicators.
• Analyze till composition for geochemical and indicator mineral signatures.
• Calculate surface exposure ages using terrestrial cosmogenic isotope data from sampled boulders and bedrock.

Strengths

• Data from 49 distinct observation stations provides multiple points of analysis.
• Field campaign conducted over a defined 12-day period in July-August 2025.
• Includes multiple data types: locations, photographs, and samples for different analyses.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Analytical results for samples are not included in this release.
