MEGATEM II Survey: Airborne Geophysical Data for Central Stevenson Ridge, Yukon

Airborne electromagnetic survey data covering the central Stevenson Ridge area in Yukon, Canada. The survey was conducted with a flight line spacing of 400 meters and a nominal EM receiver terrain clearance of 60 meters. The dataset is provided by the Government of Yukon and was last updated in May 2026.

Use Cases

• Map subsurface conductivity anomalies based on airborne electromagnetic (EM) data.
• Identify potential mineral deposits based on geophysical signatures from the survey.
• Plan ground-based exploration follow-up based on the 400-meter flight line spacing.
• Analyze terrain clearance effects on EM data quality based on the 60-meter nominal receiver height.

Strengths

• Survey parameters are specified, including a 400-meter flight line spacing.
• Nominal EM receiver terrain clearance of 60 meters is documented.
• Dataset is provided under the open OGL-CA-2.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and overall data volume are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific survey area in Yukon.
